The new Chevy Corvette coupe and convertible will get a little bit closer to its extremely fast Z06 brother performances. In 2007, the LS2 6.0 liter V8 has been removed from the fibre glass engine compartment and replaced with a brand new, with enhanced structure, all aluminum 6.2 unit.The new engine LS3 has SAE certification and its technical specifications are 430 hp and 424 lb-ft of torque with the standard exhaust system, or 436 hp and 428 lb-ft with an optional dual-mode exhaust. This engine is, at 6200, only400 rpm far away from Z06 (7000-rpm maximum speed).The LS3 has borrowed some of the technology from the Z06’s LS7 7.0-liter (like the cylinder head design and the fuel injectors) and it has the same stork as the previous 6.0 liter. It has an increase in displacement, which originates from an increase in bore from 101.6 mm to 103.3 mm and a new camshaft lifts 5 percent higher the intake valves which are also larger than the old engine (with 9%).The engine cover and the acoustically tuned intake manifold will provide the LS3 with a better, more refined sound, which is piped through an exhaust tubing system of 2.5 inches (half inch smaller than that from the Z06).The base Corvette has now a coefficient of drag of and 290 mph and improvements do not end here, because there are also tactile enhancing on both six speed transmissions. Shifts in the automatic can be changed a whole lot quickly now, reaching a 0-60 mph in 4.3 seconds which represents the highest reached by a 2-pedal Corvette.The wheels on the 2008 model are measuring 18 inches diameter infront and 19 inches in the rear. They are made from aluminium and they bring another improvement on the list: steering feel is better and that is also due to the improved machining process.Now, on the interior, the list of improvements continues. Starting from the brushed aluminium accents, XM radio equipment, auto dimming mirrors and finishing with the iPod jack for cars without navigation, they all bring a great feel of elegance combined with sporty utility.The colours available are Jetstream Blue Metallic Tincoat and Crystal Red Metallic Tintcoat.Corvette proves once again that it can face all the technological changes in the supercar world and with the continuous changes it becomes a great alternative for supercars fans, as it usually costs two and sometimes three times less than many supercars.

The most powerful Mustang ever, the 2008 Shelby GT500 KR is to be unveiled at the New York International Auto Show. This new car will mark once again Mustang as KING OF THE ROAD, at the 40th anniversary of the 1968 Shelby Cobra GT500KR.
The one who has been responsible for keeping the original Shelby muscle car spirit is Doug Gaffka, Ford SVT chief designer, together with his team and Shelby team.The carbon composite hood has been custom designed and it was mainly supervised by Gary Davis, vice president of production and product development for Shelby Automobiles. He has managed to give a visual indication of the extra horsepower that lies underneath the hood, by sculpting a modern version of the original hood scoop.
The polished aluminum, Shelby-designed 20 inch, forged and polished wheels bring once again the exclusive spirit to front. The models that will enter production will arrive at the customer with the 18-inch version of the design.The engine is a 5.4 L supercharged V8 which brings the “King of the Road” to 540 horsepower and 510 lb-ft. of torque. A six-speed tranny helps power to get to the rear wheels.The Shelby Team has worked closely with Ford’s SVT and Racing teams in order to recalibrate suspension and to bring improvement to the steering and handling. Features of recalibration include advancing the ignition timing and also re-mapping of the electronic throttle settings. This will bring a quicker throttle response for better off-line and middle range acceleration.As expected, the production will be a 1000 units limited one and it will start arriving to Ford Dealers in the spring of 2008. Every single one of the limited 1000 KR models will be identified 40th anniversary KR badges on fenders and grille.
