Acura unveiled a prototype of ZDX four door coupe at the 2009 New York International Auto Show. The Acura ZDX is 192.4 inches long, 78.5 inches wide and 61.8 inches tall and has a wheelbase of 108.2 inches. The Acura ZDX prototype power gets from a V-6 engine mated to an all-new, sleek shifting 6-speed automatic transmission. The potent powertrain will be coupled with Acura’s exclusive Super Handling All-Wheel DriveTM (SH-AWD) system

A egend is reborn. After all, powerful five-cylinder gasoline engines have a long legacy at Audi. And the turbocharged direct-fuel-injection engine in the TT RS is the new torchbearer of this dynamic tradition. It enables the TT RS to perform extraordinary feats. For example, it needs nowhere near five seconds to reach 100 km/h (62.14 mph); overtaking is child’s play; and 250 km/h (155.34 mph) is the limited top speed only on paper.

The quattro permanent all-wheel drive system, a sophisticated chassis, and stupendous brakes keep a tight rein on the power. All in all, the compact TT RS – with its lightweight and largely aluminum body constructed as per the Audi Space Frame principle – is a driving machine to be reckoned with

In Short: All GS models receive minor enhancements. A revamped grille, new wheels, and taillamp tweaks set off an otherwise carryover GS 450h. GS 350/460 retain their 2009 looks but add Bluetooth, iPod/USB inputs, and Safety Connect while losing their cassette players. Revised optional nav systems also gain new Lexus Enform telematics
