Audi bringing new TT Roadster to Paris

The TT may be first and foremost a coupe, but in presenting the third-generation model, Audi has toyed with all sorts of body-styles. There's been the prototypical coupe, of course, but also shooting brake and crossover concepts. The one thing it hasn't shown us is the convertible model, but that ends today as Audi takes the wraps off the new TT Roadster and TTS Roadster.
Set to be unveiled at the Paris Motor Show next month, the new TT Roadster naturally follows its fixed-roof counterpart's lead closely, but with the addition of a folding fabric roof mechanism. Made of magnesium, aluminum, steel and plastic, the mechanism weighs 6.6 pounds less than its predecessor's, helping keep the center of gravity lower. It also folds flatter to allow for more luggage space, and can deploy or retract in ten seconds at speeds up to 31 miles per hour. With the roof up it's also quieter, and with a drag coefficient of 0.30, Audi claims it's the slipperiest in the segment.
Of course, Audi's also worked to keep the weight down and rigidity up. As a result, the 0-62 sprint only takes an extra 0.2 seconds, quoted in the TTS Roadster at 4.9 seconds instead of 4.7 in the TTS coupe. Top speed remains pegged at 155 miles per hour. That, of course, is with the top-spec, 310-horsepower 2.0-liter turbo four, but Audi will also offer the less potent 184-hp version as well as a 2.0-liter TDI, mated to either a six-speed manual or six-speed DCT, though specific performance figures for each version were not disclosed in the press release below.

Audi debuts all-new R18 E-Tron Quattro with novel secondary hybrid system

This is the new Audi R18. It looks like the Bond villain of race cars (it has red running lamps), and if Audi's past is any indication, it'll prove difficult to beat in the LMP1 class of the 2014 World Endurance Championship.
The car's full name is the Audi R18 E-Tron Quattro, just like last year's car. Also like last year's car, the new R18 draws its power from a V6 turbodiesel, which powers its rear wheels, and Audi's E-Tron hybrid system, which runs its front axle. Unlike last year's car, though, this R18 has a secondary hybrid system. Audi has fitted the V6 with an electric turbocharger and figured out how to capture waste heat generated when the engine reaches its boost limit. That power can then be stored and fed back into either the turbo or the front axle's hybrid system under acceleration.
There are a number of changes to the body on the new car, forced in large part by series regulation changes. The car is narrower, particularly at the front, but it's also taller. The front end is set off by a new wing, as part of a new WEC regulation. Audi seems quite pleased about this, citing an improvement in front-end downforce and a reduction in cost. Like Formula One, the WEC contenders now have to contend with a ban on the so-called blown diffuser, which forced exhaust gases over the diffuser, creating downforce. That's necessitated some changes from Audi, although as we have no rear shots of the car, we can't tell you what it looks like.

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.
