New Range Rover 2013


Expected to go on sale later this year as a 2013 model, the new Range Rover is believed to feature a light-weight, rivet-bonded aluminum chassis primarily based on a changed version of the platform underpinning the Jaguar XJ.
Powertrain choices can largely carry over from the present model and embody naturally-aspirated and supercharged 5.0-liter V-8s, moreover as a combine of recent turbodiesel units for overseas markets. Output can range from concerning 260 to 510 horsepower. additionally due out some of years once the initial launch could be a hybrid version giving a combined fuel economy as high as 33mpg.








The range Rover SUV is crucial for Land Rover as its not solely the model that best defines the complete, however it’s additionally the one that almost all of Land Rover’s alternative vehicles are primarily based on.

Models just like the range Rover Sport, LR4 (Discovery) and LR2 (Freelander) all share their basic style and technology with the range Rover, thus as you'll expect engineers have plenty of pressure resting on their shoulders developing the next-gen model.

By using the light-weight material, engineers might shed up to 40 % from the burden of the present model’s unpainted body shell, equating to a saving of roughly 660 to 880 pounds. Advanced composites also are expected to be used for bound parts, like the body panels and rear tailgate.

This would offer the vehicle a final curb weight roughly equal to a fully-loaded luxury sedan, improving each performance and fuel economy--the latter of that is anticipated to be as high as 33.3 mpg combined for a few models. This same platform will spawn a new-generation range Rover Sport, that is anticipated to exchange the LR4 model in Land Rover’s lineup and be accessible with seven seats for the primary time.

The vehicle appearance to be slightly longer than today’s model, with its roofline significantly lower moreover. this could lead to lower drag and a smaller overall look. The new headlights will feature a cluster of LED daytime running lights as revealed in a number of the spy shots.

Ferrari 599XX


These are of the Ferrari 599XX and directly responsible for the pool of drool at my feet right now. Based on the 599 GTB Fiorana, the Ferrari 599XX features the latest application of Ferrari's extensive research in F1 racing to a road going car. It's clear on looks alone that the Ferrari 599XX will be the most extreme version of this car to come from Maranello, and we don't even know what's been changed beneath its skin.


Except for the roof and windshield, not much of the Ferrari 599XX is cannibalized from the all-aluminum 599GTB Fiorano. All four fenders, for instance, feature F1-like aero “fences,” vertical panels behind which air is scooped out from each wheel well. To relieve heat and pressure, the hood likewise features nearly as many holes as Augusta. The winglets on the C-pillars—resembling Alfred E. Neuman’s ears—funnel air inward, forcing it to slide down the Lexan backlight, then along the ducktail trunklid, and finally over the carbon-fiber blade spoiler. And then there’s the huge underbody fairing and rear diffuser, whose center section is air permeable.

Two electric fans mounted inside the trunk suck air through that permeable panel and then vent it through the holes previously occupied by taillights. The air is discarded in individual huffs and puffs (like a subwoofer stomping out rap music), which, we are told, detaches the wake from the rear of the Ferrari 599XX. This is apparently a good thing, according to the F1 engineers who designed it—along with the winglets—during hundreds of trial-and-error hours in Ferrari’s own wind tunnel. The fans automatically quit sucking underbody air at 155 mph, a speed that suggests the car is traveling in a straight line and thus needs no extra downforce. Speaking of which, all of this aero chicanery creates 617 pounds of downforce at 124 mph and 1389 pounds at 186 mph. For what started as a street car, that’s a bunch.

The Ferrari 599XX 6.0-liter V-12 makes 720 horsepower and 506 pound-feet of torque, besting the Ferrari 599XX GTB’s output by 108 prancing horses and 58 pound-feet. Some of that newfound power accrues from upping the redline—9000 rpm instead of 8400—made possible through extra balancing, blueprinting, and sedulous massaging. There’s a new higher-flow carbon-fiber intake manifold, for instance; the pistons are graphite-coated; the cam lobes are polished to a Bulgari-quality fare-thee-well; mechanical tappets replace the hydraulic-istas; there’s a custom exhaust; and the crankshaft throws have a new aerodynamic profile.

How to Clean Foggy Headlights


My headlights are really foggy, I dont know if my seal is broken or not. My lights are fine and work - it's just the headlights are foggy in the inside


Things You'll Need

  • 1000 & 1500-grit sandpaper.
  • Liquid rubbing compound -- fine.
  • A bucket of warm water.

4 strive an electrical buffer rather than a cloth or use a headlight restoration kit. These is found at an auto elements store, or on the web.


How to Replace fuel pump

Replacing Fuel Pump
WARNING: Gasoline is very flammable. don't smoke when performing on the fuel system, and keep any sparks or alternative sources of ignition faraway from the vehicle and fuel tank. don't use an incandescent bother light-weight close to the fuel tank because the hot surface of the sunshine bulb will ignite any fuel that may spill or splash on it. Fuel vapors are heavier than air and might additionally travel an extended distance along a garage floor. The fumes will be ignited by a heater, pilot light-weight, electrical motor or alternative supply of ignition far away. even be attentive to the very fact that static discharges also can ignite fuel. Proceed with caution.

The electric fuel tank on most vehicles with electronic fuel injection is found within the fuel tank. If there's no access panel below the rear seat or within the trunk of the vehicle, it means that you may ought to lower the fuel tank from the vehicle to switch the fuel pump. this will be a troublesome job, thus you will need to require your vehicle to a service facility for repairs instead of attempting to try and do it yourself.

Before you move to all the work of removing the fuel tank, double-check below the rear seat and within the floor of the trunk for an access panel to the fuel tank. If the vehicle has one, you'll be able to amendment the fuel pump while not dropping the tank. simply skip future few steps and undo the plate the holds the fuel pump within the tank.

Before unbolting the straps that secure the fuel tank in place, take away the maximum amount fuel as potential from the tank. this can lighten the tank significantly and build it abundant easier to handle, lower and raise back to place. Some gas tanks have a drain plug within the bottom, however most don't thus might} ought to use a hand siphon pump to empty the tank (do NOT use an electrical drill powered pump because the sparks may ignite the fuel!). Insert the water the filler neck and use the hand pump to start out the siphon action. don't suck on the hose to start out a siphon as a result of gasoline is toxic and therefore the fumes will damage your lungs. Drain the fuel into an approved container (a metal or plastic gas will, NEVER an open bucket), and seal the container once all the fuel has been drained from the tank. don't leave open containers of gasoline sitting around.

Make sure the parking brake is about, the transmission or transaxle is in park, and therefore the front wheels are chocked with blocks or bricks that the vehicle cannot roll after you raise it. The vehicle ought to even be parked on a level surface.

Raise the rear of the vehicle as required with a jack, and support the vehicle with a minimum of 2 jack stands (make positive the stands have the correct weight rating to handle the burden of the vehicle). NEVER crawl below a vehicle that's solely supported by a jack.
Disconnect the filler neck from the fuel tank by loosening or removing the clamp that holds the hose on the tank.

Remove either the front 2 bolts or the rear 2 bolts that secure the fuel tank straps to the vehicle. Then gently lower one finish of the tank. this can enable you to achieve the wiring connections, fuel line and vent hoses on prime of the tank. Disconnect the wires and hoses before removing the 2 remaining bolts that hold the opposite finish of the straps. The tank will currently be lowered from the vehicle.

remove fuel pump from tank
Once the tank is sitting on the bottom, you'll be able to undo the plate on the highest of the tank the holds the fuel pump in place. The plate might have a metal ring that has got to be rotated counterclockwise to get rid of the ring. Or, the plate is also held in place with screws or bolts. Once this plate has been loosened, the plate, fuel pump and sending unit will be fastidiously pulled out of the tank.

Pump and Tank Inspection
Clues on why the pump failed is also found by examining the filter screen on the pump inlet, and peering into the tank itself. If the filter screen is clogged with dirt or rust, the fuel tank can in all probability ought to be cleaned or replaced. Dirt will be removed by steam cleaning or pressure cleaning the within of the tank and permitting it to dry. If the fuel that was drained from the tank is dirty, it ought to be disposed of or run through a low filter before it's reused. If the tank is steel and it's rusty within, you must replace it with a brand new one. The gas tank ought to even be replaced if it's leaking.

new fuel tank
When you install the pump within the tank, place a brand new filter screen on the pump (a new screen typically comes with the pump). a brand new gasket or seal ought to even be put in on the highest plate to stop leaks. If the fuel line or vent hoses are recent and cracked, they must get replaced additionally.

fuel pump inlet filter
Raise the tank high enough that the fuel pump wires, fuel line and vent hoses will be reconnected, then end raising it and install the support straps to carry the tank in place.
Reconnect the fuel filler tube, then add fuel to the tank and check for leaks. The tank ought to be a minimum of 1/4 full to supply enough fuel for correct fuel pump lubrication and cooling.

Replacing the fuel filter at now is additionally suggested.

10 Ways to Waste Gas

There are only two ways to get significantly better gas mileage with your current vehicle: Drive less and slow way down. However, there are many easy ways to get worse mileage. You're probably already practicing many of them, perhaps not realizing you're stomping your carbon footprint by waste gas and polluting the environment.

Here are the top 10 ways to waste gas

1. Stand on the gas

There's little a carbon stomper enjoys more than blasting along at 90 mph — other than doing it in a Suburban while towing a big trailer. You can get about 5 mpg if you try. On the highways I travel, there's no shortage of huge SUVs and other vehicles travelling at or near that speed.

2. Use E85 ethanol.
Ethanol significantly drops fuel mileage because alcohol contains less energy than gasoline. The EPA says you'll get about 7 mpg less with E85 (85 percent ethanol, 15 percent gasoline) than with 100 percent gas. In our own tests comparing E85 and gasoline. To grow corn to make ethanol, American farmers are plowing up native prairie grass that is the primary breeding ground for waterfowl. Simultaneously, Brazilians are burning down virgin rainforests to grow sugarcane for ethanol and soybeans for biodiesel. Also, some studies say it requires more fossil fuel energy to make ethanol than the alcohol contains. In addition, ethanol must be transported by truck or railroad rather than the traditional gasoline pipeline system.

3. Idle.
A car gets zero miles per gallon while it sits motionless with the engine running. You can make a Corolla get the same gas mileage as an 18-wheeler by sitting in the car with the air-conditioner running while waiting in an elementary-school pickup line. A main way hybrid-electric cars reduce fuel consumption is by switching off their engines while stopped in traffic. For modern, fuel-injected vehicles, the break-even point for turning off the engine and then restarting it right before traffic begins to flow may be as little as 10 seconds, even when considering extra wear on the starter motor, battery and other components. Expect honks and rude gestures from drivers behind you.

4. Enter the stoplight drags.
Establish your dominance by being the first to the next stoplight. It's a race: Don't let the rats win. By accelerating hard, you're burning much more gas than you would by gently gaining speed. And you get to waste even more while idling at the next stoplight until the slow-accelerating driver arrives. Often, the light turns green right as the slowpoke arrives. Then you really have to gas it to beat him to the next light.

5. Cruise
Driving around aimlessly is such a relaxing and enjoyable way to waste gas. Harley riders, snowmobilers and teenagers have this down to a science. Some cities still boast 1950s American Graffiti-style cruising where people circulate in an intentional traffic jam around a city square — doesn't that sound fun? Gas hogs love traffic jams and lots of idling.

6. Choose max-performance tires.
There's little like the thrill of blasting around a freeway transition ramp on super-grippy max-performance tires. However, sticky tires take more energy to move down the road than do most original equipment tires. Tire engineers call it rolling resistance, and ultra-high-performance tires almost always have a lot of it.

7. Never use cruise control.
A great way to burn extra fuel when driving down the interstate is to accelerate until you pull far past another car. Then slow down until that car passes you and gets a half-mile lead. Next, gas it until you're a quarter-mile in the lead. Repeat. Not only does this drop gas mileage, it'll make you one of the world's most aggravating people.

8. Use regular gas when your car calls for premium.
The Lexus College says using 87-octane fuel in its vehicles that require 91 octane will reduce fuel mileage by about 6 mpg. This is partially because the lower-octane fuel requires the engine to work harder to achieve the same performance. It's unclear whether this is true for all makes. Try it for yourself to find out which gets worse mileage.

9. Keep your trips short.
Engines don't operate at maximum efficiency until warmed up. So you'll burn more fuel if you drive two or three miles and then stop and let the car cool down before making another short trip. To make sure you burn the most gas, never drive first to your furthest destination and make your other stops on the way home. Best of all, drive all the way home after each errand and never even think about walking or riding a bike.

10. Ignore maintenance.
A clogged air filter does a wonderful job of wasting fuel, but it's nothing compared to a malfunctioning oxygen sensor. If the "check engine" light illuminates, a small piece of black tape will allow you to keep wasting gas without the annoying nagging. Out-of-spec suspension alignment will burn more fuel, as will adding heavier-weight oil like 10W-40 rather than the automaker-recommended 0W-20.

2013 Ford Shelby GT500



Chevrolet’s unleash of the all new Camaro ZL1 at the 2011 Chicago Auto Show allowed them to reignite the muscle automotive wars that are burning up the automotive websites for a decent and lasting. however before Chevrolet will shout out "Checkmate," Ford has answered the ZL1 with an update automotive of their own: the 2013 Shelby GT500. Recent spy shots have revealed that the corporate is already testing the 2013MY GT500 and it'll be additional powerful than ever.


During our figure-eight testing, the GT500 posted a powerful twenty four.2 sec @ 0.80 g result, managing an equally spectacular zero.98 g (avg) lateral acceleration. Even better: comparing the new Shelby to its predecessor, testing director Kim Reynolds declared it, "simply a far easier automotive to drive." a part of the development is because of the Torsen differential -- another piece of the SVT Performance Package - that gives a full-time torque-sensing system to assist optimize traction and handling. Still, the recent automotive, whereas additional of some, was no slouch, edging its successor with a figure-eight time of twenty four.0 sec @ 0.82 g and most lateral acceleration of one.01 g (avg).

The Camaro ZL1’s LSA vi.2L supercharged V-8 engine manufacturing an estimated 550 HP and 550 lb.-ft. of torque is nothing to shake a stick at, however Ford has one-upped them all over again. The Eaton M112 supercharger that's being housed within the current GT500’s V8 engine are going to be replaced with the more-efficient and quieter TVS unit. The V8 engine found within the 2013 model will get changed and bumped up to five.8L, all whereas manufacturing up to 650HP and creating it the foremost powerful, factory created Mustang ever! the sport continues...Your move Chevrolet.

Ford Focus ST 2013

2013 Ford Focus ST
The Focus ST boasts Ford’s Sport Steering system, that uses a variable-ratio steering rack supposed specifically to extend agility and management for the sporty hatchback. conjointly improving handling is that the new anti-roll bar style along side upgraded shock absorbers and is derived that lower the chassis by 10mm for a additional aggressive stance and a lower center of gravity.

Looking the half Visually differentiating the main focus ST and its heightened performance potential from the quality Focus are variety of distinctive cues. except for the obligatory body kit, the automotive boasts a singular version of Ford’s signature trapezoidal grille that's arguably additional elegant than the somewhat fussy unit of the quality Focus st. A roof spoiler helps to stay the automotive planted in high-speed things, whereas the piece de resistance may be a hexagonal center-exit exhaust pipe that lends a singular look to the rear fascia.

Inside, the automotive edges from special details like aluminum pedals, an focus ST-specific steering wheel and gearshift, whereas racy Recaro seats are optional and obtainable in either partial or full leather. Even the rear bench has conjointly been re-sculpted to produce additional support throughout sporty driving.

Sounding the half Ford is that the latest in an exceedingly growing range of automakers to electronically manipulate and augment the aural part of its models. To that finish, the main focus ST is supplied with a sound symposer box that “enriches the natural sounds of the motor by capturing internal engine oscillations and piping them through the inside below throttle,” the corporate says. In part-throttle driving, the system keeps the mechanical noises to a minimum; below full throttle, engine noise is amplified through the symposer box.

Standard and Optional options Standard options on the main focus ST embrace Ford’s SYNC connectivity system, 18-inch alloy wheels, intelligent access with push button begin, a leather-wrapped steering wheel and foglamps.

Two optional equipment package are obtainable for those seeking a well-equipped hot hatch.
Equipment cluster ST2 adds a premium Sony audio system, HD radio, dual-zone automatic climate management and Recaro partial-leather seats. To those options, Equipment cluster ST3 adds a navigation system, HID headlights, ambient lighting, heated mirrors and Recaro full-leather heated thrones.

Occupant Safety Every Focus ST leaving the factory comes normal with twin front, facet and facet curtain airbags additionally to traction and stability management systems and a tire-pressure monitoring system.

Key Competitors It’s an honest time to be within the marketplace for a reasonable, compact-sized performance machine – If the main focus ST isn’t for you, sturdy alternatives embrace the high-revving Honda Civic Si, the all-wheel-drive Subaru Impreza WRX and therefore the refined Volkswagen GTI.

Self Repair your car body scracth


You don't need fancy tools to distinguish a scratch from a mark. A fingernail drawn over the surface at 90 degrees to the defect will tell you if it's gouged into the paint or sitting on top of it. If it's a mark that appears to be from rubber, plastic or even other paint, it may come off easily with an aerosol tar or adhesive remover.

Stubborn scratch marks often can be removed with acetone or lacquer thinner on a soft rag. If the mark is still there after using one of these solvents, try hand rubbing or polishing compound. First, clean the area with soap and water, then spread rubbing compound on the mark and rub the area in a circular motion until the mark disappears.

Once the scratch gone, switch to a back-and-forth motion to remove circular buffing marks. Buff the area with a clean cloth to remove rubbing compound. Then, using a fresh pad, clean the area with polishing compound to remove the fine scratches left by the rubbing compound. Finish by sealing the surface with a good car wax.

1. Shoe polish can be used to visualize the scratches.

2. Wipe the shoe polish over the panel. This fills the scratches with polish.

3. Block sand the panel with 2000-grit wet/dry sandpaper and plenty of water. Sand until the shoe polish disappears.

4. Polish out the sanding scratches with rubbing compound.

5. A polishing wheel makes short work of bringing the shine back. An oscillating polisher is less aggressive than this rotary polisher. Don't buff through the paint into the next layer, especially on high-crown or sharp edges.

6. Finish with light hand buffingto remove the last of the compound. Follow with car wax.

Body paint scratch repair

Whether your daily driver may be a used vehicle that came with its own set of dings and scratches, or you've got simply suffered the primary assault of an errant looking cart on a replacement auto, don't fret. Repairing minor body injury is neither a troublesome nor intimidating task. With the assistance of typical workshop tools (such as a sander and an electrical drill) along side somewhat elbow grease and a few common provides from your native auto elements search, these scratches and dings will all disappear.

The first step for any body repair method is to start out with a clean automobile, using automotive cleaning merchandise followed by an honest bug and tar remover to get rid of the layers of wax, grease, and deposits. The techniques for a body repair are additional a matter of finesse and bit than muscle. Also, take the time to browse the directions on your body repair kit (screen, putty, primer and touch-up paint) for curing and drying times. We'll begin with repairing straightforward scratches:

Simple Scratches

Using terribly fine sandpaper (one designed for wet sanding) and a water-soaked sponge, feather the perimeters of the scratch, about to vacant metal if necessary. What you are looking for may be a swish taper from the scratch to the unmarred paint. you recognize you are there after you will run your finger gently over the realm while not feeling even a trace of a position.

If the scratch is deep, you'll be able to fill it with body putty or filler. the simplest thanks to verify if body putty is needed is, again, to run your hand over the realm. Unless you have a practiced eye, simply viewing the realm is deceptive. Your fingertips and palm are your best tools. Wet-sand the putty to mix the perimeters.

Make sure the realm surrounding the injury is masked off—at least 3 inches is good—to guarantee an honest mixing of the repair coat. Apply the primer and wet-sand the realm with further fine sandpaper and your wet sponge for the simplest bonding of the ultimate paint.

Auto makers build it straightforward to match the first paint with color codes and touch-up kits accessible from auto provide retailers or the native dealer. Once the ultimate color has been applied and dried, do the ultimate sanding with 1000-grit wet sandpaper. Once you are positive the paint is totally dry, use rubbing compound to say the shine on the new paint.
Eradicate Rust

For rust, the foremost necessary issue to recollect is to eradicate all the corrosion on your initial attempt. If you do not, you will be chasing that very same rust spot for the lifetime of the vehicle or the remainder of your life, whichever comes initial. Here are the essential steps to follow:

Grind the rust right down to vacant metal. An orbital, or circular, sander is that the best tool for this job, however it will be done by hand. Again, your goal may be a taper from the rust space out to scrub metal out to smart paint.

Here's where the electrical drill comes into play. Drill holes round the space beyond the first rust spot, forming a base for the body repair screen. Cut the adhesive-backed repair screen to suit over the rust space however at intervals the drill holes. place the repair screen in place.

Once the patch has cured, apply body putty, shaping and sanding for a swish, seamless transition from the repaired space out to the first paint.

Car engine won't start in the morning


My Engine
My Engine (Photo credit: Timitrius)
Your Engine car may not start for a number of reasons. The following list outlines the most common circumstances and tells you what action you can take to try to remedy each situation:

The Engine car is silent when you turn the key in the ignition. Check the battery terminal cable connections. (See How to Check Your Car Battery.) If they look very corroded, force the point of a screwdriver (with an insulated or wooden handle) between the connector and the terminal post and twist it to lodge it firmly. Then try to start the engine again. If it starts, you need to clean or replace your cables.

The Engine car makes a clicking noise but won't start. This sound usually means a dead battery. If not, check the wiring to and from the starter for a loose connection.

The car cranks over but won't start. Check the fuel supply to your engine. If that's okay, check whether the electrical spark is getting to your spark plugs.

The engine starts but dies. If your car has a carburetor, check your carburetor adjustment and your choke to see whether the choke is first closing and then opening. If you have fuel injection, you'll need professional help.

The Engine car won't start on rainy days. Check inside the distributor cap for dampness. If you find moisture, get some mechanic's solvent from your friendly service station — they use it to clean car parts — or buy an aerosol can of it at an auto supply store. To evaporate any dampness inside the distributor cap, turn the cap upside down and pour or spray some solvent into it. Swish it around and pour it out. Then dry the cap as best you can with a clean, lint-free rag and replace the cap.

Use only clean solvent; even a tiny speck of dirt can foul the points. Gasoline won't do because a spark can ignite gasoline fumes and cause an explosion or a fire.

The Engine car won't start on cold mornings. For vehicles with carburetors,check the choke. Is it closed? Does it open? If you have fuel injection, you'll need to have a professional diagnose the cold-start problems.

The engine misses while idling. Check the points (if your car has a non-electronic distributor) and the spark plugs. (How to Remove Old Spark Plugs explains getting bad spark plugs gone.) Also check the fuel pump, fuel filter, and carburetor, if you have one. (If your fuel filter’s the problem, check out How to Change Your Vehicle’s Fuel Filter.)

The engine misses or hesitates during acceleration. Check the accelerator pump in the carburetor (if equipped), the spark plugs, the distributor, and the timing.

The engine knocks or pings. Check your timing; also check the octane rating of the fuel you're using. The owner's manual can tell you whether your vehicle needs regular unleaded or premium gasoline. Check the cooling system. (which The Essentials of Checking and Maintaining Your Vehicle’s Cooling System explains) Do a compression check on the engine cylinders.
