2012 camero

The 2012 Camaro ZL1 is the highest-performing production Camaro of all time. It is literally like nothing you've ever driven before. Built to be track-capable right from the showroom, and tested on some of the most rigorous tracks around the world, including the Nürburgring, where it clocked in at 7:41.27. This is the car every engineer dreams about building. Every racer dreams about tearing around the track. And every owner dreams about—a sports car that looks mean, but feels comfortable and docile enough for daily driving.In 1969, 69 regular-production Camaros were installed with ZL1 all-aluminum racing engines. In that moment, those mythical 69 cars became the pinnacle in Camaro performance. Every part. Every function. Every feature. Every piece of the ZL1 has been rigorously put to the test. From the Milford Road Course to the drag strip to the Nürburgring, this car has been wired up, pounded on, checked, re-checked—it's the first model year and the 2012 ZL1 has already paid its dues.

ecoboost

If you're not ready for the notion of a V-6 engine in a full-size pickup truck, you're probably even less prepared for the thought of a twin-turbo V-6 challenging some of the best V-8s in the business for truck performance.

That's the case with this year's 2012 F-150, which gets four new powertrains this year, including a base V-6 and a pair of newly developed V-8 engines. The fourth option: Fords 3.5-liter, twin-turbo EcoBoost V-6, an unlikely but completely common-sense alternative to V-8 thirst and thin V-6 torque.

It's a careful step into the future of truck performance by Ford. Coming fuel economy rules mean that all vehicles have to get better and wiser about using fuel. Since the F-150 has traditionally been a mostly V-8-powered affair, the EcoBoost had to be as good--or better--than the V-8 options on the table. The new EcoBoost engine, in this application, breathes out 365 horsepower and 420 pound-feet of torque. That's much stronger than 2010's top engine, a 5.4-liter V-8 with only 310 horsepower. Twinned with the new standard six-speed automatic, the EcoBoost's power is essentially V-8-like down low, where it counts. There's some low-frequency booming that doesn't sound at all like a V-8, but in reality, the basic V-6 block and heads share some family with Ford's new 5.0-liter and 6.2-liter V-8. If you need more proof of its streetability, check out the YouTube video below of a classic V-8-ish smoky burnout, courtesy of the EcoBoosted F-150.

chevy vs ford

Ford versus Chevy. Is there a longer-lived, more deeply-rooted rivalry in all of automobiledom? If there is we don’t know about it. The latest round in this nearly century-old grudge between brands happened today. Chevy unveiled it’s all-new 2007 Silverado along with the GMC Sierra. Well, only hours later Ford gave us the skinny on the updated 2007 F-150.

Here’s the low-down on both pickups

The GM pickups are all new and based on the GMT 900 architecture it shares with the new Tahoe and Yukon. The frame is said to be 234 percent stiffer torsionally and 62 percent better in bending. Engines range from the venerable 195-horse 4.3-liter V6 on up to a 400-horsepower, 6.2-liter V8 on the Sierra Denali. Most will come with the 315-horsepower 5.3-liter V8 with Active Fuel Management, which has an estimated highway mileage of 20 mpg. All engines will be paired to a four speed automatic or a six-speed auto in the case of the Sierra Denali. Top dog models can tow 10,500 lbs.—a staggering weight for a light duty pickup. Stabilitrak comes standard on crew cab models and is optional throughout the range. The interiors are much improved and on some models include a massive 6.1-liter storage console. Expect to see the new Chevy Silverado and GMC Sierra in dealerships this winter.

The new F-150 is essentially a carryover. But Ford made sure to say that the F-150 now has a towing capacity of up to 10,500-lbs. Yep, just like the Chevy and GMC.ll  New models this year include a 2WD FX2 sport model and a Harley Davidson SuperCrew model. Ford also says it will lower prices on ’07 F-150s by up to $1400 on some trucks.

The Crown Victoria Police Interceptor, also referred to as the CVPI, is a series of law enforcement vehicles assembled by Ford Motors. The 1992 Crown Vic police car models were officially termed the 'P71 Crown Victorias' or the 'P71 Crown Vics'. Even when these vehicles were officially reclassified as Police Interceptors, they preserved the P71 tag. The Interceptor became one of the most widely used cars in Northern American police departments. Taxi companies also preferred the Interceptors due to their reliability and endurance levels. The 1998 P71 Interceptor had an over all chrome re haul, which included chrome bumper strips, chrome-trimmed flat black rear fascia, chrome door handle trim, and a chrome grille. When the 1999 P71 was upgraded, it's newest addition was a brand new 'Police Interceptor' insignia, along with black door handle trim, a chrome-trimmed gloss black rear fascia, black bumper strips and a gloss black slatted grille. The 2000 Crown Vic P71 saw the inclusion of a flat black slatted grille and the chrome trim was eliminated from the rear fascia and taillights. The 2001 P71 design banished all the trims on the plastic bumper pieces and the addition of a honeycomb-style grille. By 2003 it was time to pay some heed to the interiors of the car and that is exactly what the designers did. Not only did they refurbish the interiors, but they also included safety measures such as side impact air bags. Though not much difference lies between the models released between 2001 and 2006, the most evident change could be spotted in their wheels; as the brakes, suspension, steering, and the frame were all transformed for the 2003 model. The 2004 model on the other hand got a new air intake system. Even though the Police Interceptors are not made available to the general public, used and abandoned Interceptors form the law enforcement department are used as used cars.

Chevy Cruze Eco

Forget Chevrolet's star-crossed small cars of the past. The new 2011 Cruze Eco flat-out works. Like the Focus, the Cruze Eco features aerodynamic slats behind the grille that automatically open at low speeds to keep the engine cool, but then close when cruising to reduce drag. And, of course, it has low-rolling-resistance tires. The star here is a 138-hp, 1.4-liter turbo motor that performs like a much larger engine. To enable the Cruze's 42-mpg highway rating, the Eco's engine is lashed to a six-speed manual transmission, with overdrive ratios for the top three gears. At a steady 70 mph, the tiny engine is only turning about 2000 rpm, but even the slightest grade can mean downshifting to third. The Cruze's rear seat is tight, but the interior mixes interesting textures and quality switchgear. On the outside, the Cruze wears beautiful crimson paint and blingity-bling chrome wheels. It looks expensive, yet carries a modest $19,745 sticker.

new chrysler 300

We all know that the traditional large, rear-wheel drive american sedan is slowly diminishing.The 2012 Chrysler 300 c carries on the tradition of the large, rear-wheel-drive, American sedan, but adds ride and handling characteristics vastly improved over the Jell-O-shot and bungee-cord-sprung domestic land barges of yore. And technically, that’d be North American sedan, as the engine originates from Mexico and the vehicle’s final assembly takes place in Chrysler’s Brampton, Ontario, facility. (Well, the transmission comes from Germany.) That aside, one early logbook entry may have set the tone for this car’s 40,000-mile stay when it asked, “Is this the last great, large, rear-drive, V-8–powered American car?

turbocharger compared to supercharger

Turbochargers are  more difficult to control due to the high temperatures they generate and the way they produce a dramatic rise in air pressure, resulting in large horsepower increases. Although this may sound ideal it usually results in uncontrollable wheel spin and loss of handling to the point of making driving dangerous, forcing the driver to back off and losing the benefits of all this power. All these problems of a turbocharger can be tamed to a certain extent but it involves much extra technology and cost. Apart from this drivability problem the other downside is that this sudden rise in pressure, means very careful engine management adjustments to set the fueling and ignition correctly to avoid engine blow ups. Several Saxo turbo's that we have heard of produced reasonable power but destroyed themselves and the installer then rebuilt them with lower boost to preserve the engine. This did cure the reliability but then power was way down.. Another downside of turbo's due to the very rapid increase in power, is the effect on the transmission components, all turbo's wear out clutches and gearboxes more quickly. These components like gradual torque increases not sudden violent increases.

removing pinstripes

Removing pinstripes from a car can be a time consuming task. You start off by heating the stripes with a hair dryer or heat gun. After this you peel the stripes while heating in front of them. You need to be careful not to heat it to much because this will cause the paint to chip. If the stripes are stuck on and falling apart spray wd 40 on them and let them soak for 15 minutes then try. You also want to be careful peeling and scraping them off so you dont scratch the paint;.You may need to scrape them off with a plastic putty knife. After you get the pinstripes off there will be an adhesive left over on the paint and you will need a pinstripe eraser wheel to remove that. This is done by putting the wheel in a drill and horisontaly or vertically running it over the adhesive, you must be careful to keep the wheel under 4000 rpms or the wheel could break and it could damage the paint. The eraser wheel is a very time consuming task and can make your arms tired.

There is no clutch pedal in an automatic transmission car.
There is no gear shift in an automatic transmission car. Once you put the transmission into drive, everything else is automatic.
Both the automatic transmission and a manual transmission accomplish exactly the same thing, but they do it in totally different ways. It turns out that the way an automatic transmission does it is absolutely amazing.
The key to the modern automatic transmission is the torque converter. It takes the place of a clutch in a manual transmission.
A direct descendant of an earlier component called a fluid coupling, the torque converter offers the advantage of multiplying the turning power provided by the engine. It is connected to the motor by means of a metal rod known as the transmission shaft Inside the torque converter are several components that help multiply the power. These are the impeller or pump, the turbine, and the stator or guide wheel.
A torque converter is like a giant doughnut. The impeller and the turbine  face one another inside the round metal casing. The impeller is on the engine side, the turbine on the tranny side. Both of these components have blades that catch the transmission fluid and cause them to spin.

­The purpose of a gasoline car engine is to convert gasoline into motion so that your car can move. Currently the easiest way to create motion from gasoline is to burn the gasoline inside an engine. Therefore, a car engine is an internal combustion engine combustion takes place internally. There are different kinds of internal combustion engines. Diesel engines are one form and gas turbine engines are another. See also the articles on HEMI engines, rotary engines and two stroke engines. Each has its own advantages and disadvantages.There is such a thing as an external combustion engine. A steam engine in old-fashioned trains and steam boats is the best example of an external combustion engine. The fuel (coal, wood, oil, whatever) in a steam engine burns outside the engine to create steam, and the steam creates motion inside the engine. Internal combustion is a lot more efficient (takes less fuel per mile) than external combustion, plus an internal combustion engine is a lot smaller than an equivalent external combustion engine. This explains why we don't see any cars from Ford and GM using steam engines.
this is just a little knowlage on engines.
