Garrett Turbo

Ronnie Tanner asked:




The Audi A3 features a two liter turbo-charged engine that makes the car a nimble and quick performer. The turbo-charged engine runs on premium unleaded gasoline, and fuel is is inducted into the engine via a direct injection system. This powerful engine is mated to a six speed manual transmission. The engine produces two hundred horsepower at five thousand one hundred revolutions per minute; the engine produces two hundred seven pounds of torque at one thousand eight hundred revolutions per minute. These performance figures make this engine one of the most powerful available in a small car. The engine also features four valves per cylinder, in addition to the aforementioned turbo-charger. According to the Environmental Protection Agency, the turbo-charged engine returns twenty-one mile per gallon in city driving and thirty miles per gallon in highway driving. Audi has held over from the 2009 model the all wheel drive system, although the all wheel drive system is available only on the base two liter engine without the turbo-charger. The other major change from the 2009 model year is that Audi has decided to drop the six cylinder engine as an option on the A3. The 3.2 liter six cylinder was a smooth and powerful performer, producing two hundred and sixty-five horsepower. The negative aspect of that engine was that it returned only fourteen miles per gallon in city driving. Audi has elected for the 2010 model year to not make any major changes to the A3, but rather make the A3 a roomy, sporty wagon that is able to return good fuel economy in an attractive package.

rs are traditionally rear-wheel drive. As is the 2010 Hyundai Genesis Coupe. Similar to a RWD racer, the Genesis Coupe 2.0T model is quick, responsive and fast. The standard engine is a 210-hp, turbocharged, four that makes a whopping 230 pound-feet of torque at a very low 2,000 rpm. Pricing for the 2010 Hyundai Genesis Coupe 2.0T is under $25,000.

The main purpose of front-wheel-drive, contrary to popular misconception, is to increase interior room. (And, if you haven’t heard, additional weight is not “road hugging.”) With a front-drive car, the front tires must do all of the acceleration and steering and about 80 percent of the braking, while the rear tires’ main job is to keep the gas tank from dragging on the pavement. This means a front-driver has more difficulty simultaneously accelerating and turning (or turning and braking). With a rear-drive car, the rear tires concentrate on putting power to the ground, while the fronts focus on turning and/or slowing down. The bottom line: A rear-drive car will always beat an otherwise identical front-driver around a dry racetrack or up a mountain road. Not to mention, a rear-wheel-drive car can do things no stock front-drive car can do: drifting powerslides and hooning, smoky burnouts. (“Hoon” is an Australian or New Zealand word translates to anti-social behavior and driving irresponsibly.)

The Genesis Coupe is also available with a 306-horsepower 3.8-liter V6. While the Genesis Coupe 3.8 V6 is notably quicker at the drag strip, the turbo four is the more enjoyable version of the car. Reasons are many: Much of the V6′s extra 100 pounds is carried on the nose, which tends to overwhelm the front tires. The four also has much lower first and second gears in its six-speed manual transmission. The combination of big torque and low gearing gives the four cylinder strong acceleration in the speed range that can be used on public roads without entering the Highway Patrol’s Frequent Offender Program. It also offers enough torque to squeal the tires leaving the line and on the one-two upshift.

The V6 moves the Genesis Coupe into a different realm. The V6 feels much less nimble than the four. Also, the V6′s manual did not react well to performance-oriented shifts, responding with harsh drivetrain shocks, as if we had never driven a manual. Also, the linkage of both manual transmissions suffered from an extremely annoying buzzing. Unfortunately, we did not have the opportunity to sample either of the automatics: five-speed with the four or six-speed on the V6.

The Genesis Coupe 2.0T will go head-to-head with the likes of the Honda Civic Si and the V6 Ford Mustang. The four-cylinder turbo is rated at 30 miles per gallon in the government’s highway driving cycle and 21 mpg. The V6 gets 26 mpg on the highway and 17 mpg in the city, when equipped with the six-speed automatic.

Both engines are available in a “Track” configuration, which includes 19-inch-diameter wheels with very sticky Bridgestone Potenza RE050A summer tires and stiffer suspension springs and anti-roll bars, as well as Brembo brakes. The summer tires will help the Coupe’s street performance but the stiffer suspension will be difficult to live with every day in pothole-plagued areas. Unless you’re really going to the track, stick with the regular model. There’s also a “R” version that removes some standard features, such as the sunroof, to reduce weight.

Safety features include six airbags, active head restraints, standard electronic stability control and anti-lock brakes. Included is a 360-Watt, 10-speaker Infinity sound system. Inside, the Genesis Coupe offers good quality materials and commendable fit and finish. This is one reason that the average residual value after 36 months for a Hyundai has improved to about 43 percent currently from 37 percent in 2005. All is not perfect as the blue on black digital information center is difficult to read, and the speedometer and tachometer are offset away from the center of vision, making them a bit difficult to follow.

The Genesis offers minimal rear seat room. Five 17-year-old girls would fit just fine, but the Genesis Coupe is a two-seater for big or tall adults. It has a hefty trunk with a pass-through for long items. Here’s the take-away: Rear-drive rules. Strong horsepower, low gearing and a low purchase are nice, too.

Skoda Auto India Private Limited rolled out Laura in 2005. The launch of this luxury sedan is a part of the Czech-based automaker’s strategy to make its presence stronger in the luxury D-plus car segment of India. With a futuristic engine technology, well-finished exteriors and classy interiors, Skoda Laura proves to be real value for money. The car is specially designed to suit the Indian roads. It performs remarkably well and astounds you with its arresting looks.

The 2009 Skoda Laura is available in three variants: Skoda Laura Laurin and Klement, Skoda Laura Elegance, and Skoda Laura Ambiente. These variants are available with a choice of three revolutionary engines: 1.8-litre TSI (Turbocharged Fuel Stratified Direct Injection), 1.9-litre TDI PD (Turbocharged Direct Injection with Pump Duse), and 2.0-litre TDI PD that generate 160 bhp, 105 bhp, and 140 bhp respectively.

The TSI engine is a combination of turbocharger, stratified direct fuel injection system, and variable valve timing. The combination of these three advanced technologies ensures higher performance and better mileage. The turbocharger in the system helps improve engine efficiency and reduce fuel consumption by supporting complete combustion of injected fuel. The fuel stratified direct injection engine technology uses stratified charging to directly inject fuel in relatively small and precise quantity to ensure optimised combustion. Variable valve timing technology helps improve engine efficiency by monitoring the opening and closing of valves in accordance with varying speed.

The 1.8-litre TSI is available in the Ambiente with a 6-speed fully synchronized manual transmission and the 2.0-litre TDI PD is available in the Laurin and Klement with a 6-speed automatic transmission. The 1.9-litre TDI PD is available in both Elegance and Ambiente with an option of 5-speed fully synchronized manual transmission and 6-speed automatic transmission.

The finely-tuned suspension system is specially designed for Indian road conditions with MacPherson strut in the front and multi-element axle at the rear. Moreover, the rack and pinion steering with electro-mechanic power steering and disc brakes add to the performance and efficiency of the car. The 2009 Skoda Laura is a blend of contemporary styling and dynamic contours. The elegant silhouette, sloping roofline, strong shoulder line, and lower sills impart a sporty and elegant appeal. The exterior of the car is beautified with chrome front grille, flared headlamps, new taillamps with a chrome central insert, and turn indicators in the external mirror.
