Audi TT Ultra Quattro Concept throws lightness at the problem

Audi is celebrating the 2013 Wörthersee Tour with a special concept version of the company's TT. The Audi TT Ultra Quattro concept tips the scales at just 2,449 pounds thanks to some extensive engineering work. The company pulled nearly 95 lbs from the car's body structure and used carbon-fiber reinforced plastics for many of its detachable body components. As a result, the concept weighs in at a full 220 pounds lighter than its production counterpart. Throw in a wicked turbocharged 2.0-liter four-cylinder engine with 310 horsepower and 295 pound-feet of torque, and you get a machine with the power to weight ratio in the supercar realm. 0-60 comes up in 4.2 seconds and top speed is listed at 173 mph.
Inside, the TT Ultra Quattro features plenty of carbon fiber trim, and designers also fitted the seats from the R8 GT to save a little weight. The buckets use CFRP for the seat frames, saving nearly 50 pounds in the process. In a world where automakers seem blind to the negative effect of throwing more heft at a vehicle, we're in love with the Ultra Quattro concept.

Audi Prologue Avant Concept points to the future of wagon design in Geneva [w/video]

The new generation Audi R8 and its LMS GT3 racing version are grabbing much of the attention at the Audi stand at the Geneva Motor Show. However, if you are more interested in seeing the brand's future design direction, just take a look at the Prologue Avant Concept that's also on display. Audi traditionally uses the Avant name for the company's wagons, but that's tweaked slightly here. The vehicle is certainly a five-door, but from some angles it looks more akin to a Porsche Panamera-like hatchback. Compared to the B-pillarless Prologue Coupe (that we recently drove), the stretched roof flows all the way to the angled rear hatch, and the result is a very elegant design. The interior tends towards minimalism with just a few screens showing the driving info. The Prologue Avant also ditches the Coupe's petrol-fueled hybrid for a 3.0-liter, twin-turbo diesel V6 plug-in hybrid with a total of 455 horsepower and 553 pound-feet of torque, which is linked to an eight-speed gearbox. Audi claims the setup reaches 62 miles per hour in 5.1 seconds and allows for 33 miles of pure electric driving. To get a sneak peek at what's next from Audi, take a look at the Prologue Avant Concept on the floor of the Geneva show in the gallery above.

2015 Audi RS7 Dynamic Edition is a pretty car for a pretty penny

Making its world debut at the New York Auto Show, and commanding a $40,250 premium over the base RS7, is Audi's new 2015 RS7 Dynamic Edition that arrives with an MSRP of $146,045 (including destination and delivery). The range-topping hatchback is designed to showcase Audi's exclusive program, which allows customers to choose choose from the automaker's long list of options and then take the customization one step further with bespoke paintwork, upholstery, bodywork and wheels.
The interior features Black Valcona leather seats with Crimson Red honeycomb stitching, and matching Crimson Red seat belts. The contrasting color is carried through to the stitching on the dashboard, center armrest, door panels, shift boot and center console. Carbon fiber inlays provide additional contrast. The exterior is offering in four colors (Ibis White, Suzuka Gray metallic, Daytona Gray pearl and Phantom Black pearl), with each arriving with performance-oriented DRC suspension (with three-stage adjustable dampers), 21-inch Gloss Black wheels, Tornado Red painted brake calipers and sport exhaust. A carbon fiber front splitter, rear diffuser and carbon fiber engine cover complete the package.
Like the standard RS7, the Dynamic Edition arrives with a twin-turbocharged 4.0-liter V8 rated at 560 horsepower and 516 pound-feet of torque. With an eight-speed automatic transmission, running through Audi's Quattro permanent all-wheel drive and a sport differential, the four-passenger vehicle will crack the 60 mph acceleration benchmark in a reported 3.7 seconds - and, thanks to cylinder-on-demand technology, it avoids a gas-guzzler tax. The RS7 Dynamic Edition arrives at dealerships in early summer.
