Audi's diesel-electric supercar is codenamed 'Scorpion'

Speculation continues as to the final nature of the diesel-hybrid Audi supercar said to arrive in 2016 or 2017. A previous report in Automobile had the halo coupe, based closely on the R18 etron quattro endurance racer, codenamed R20 and pegged to look like a Le Mans winner for the street with around 700 horsepower and 737 pound-feet of torque from a twin-turbo V6. Now Car and Driver has updated the gossip with a report that the car is internally called "Scorpion," and it will be even closer to the R18 than supposed.
CD says the heart of the car will use the R18 etron quattro's carbon fiber tub and its engine will be "taken directly" from the race car. That means a 3.7-liter V6 with a single turbo that, in ACO-spec restricted form, outputs 500 hp and 625 lb-ft - CD suspects production output could get to 600 hp - and drives the rear wheels, aided by hybrid motors driving the front wheels. And remember, at Le Mans the R18's hybrid motors can't kick in until they're above a certain speed in order to prevent Audi from getting an advantage coming out of slow corners. A street car wouldn't face that restriction.
The Scorpion would be a fulsome and undiluted example of the technologies Audi has created during its return to sports car racing. Its exterior design hasn't been finalized, with CD citing either the convoluted concept of "a retro take on the future of racing" or packaging that would adhere to the R18's looks. To make sure it is properly appreciated and sells well, production could be limited to the same 333 units as the R8 GT and A1 Quattro.

Audi 4.2-liter V8 to live again in next-gen R8

Fellow auto enthusiasts, it looks like the car gods have smiled upon us. Word is that Audi's stupendous 4.2-liter V8 will once again be available in the next-generation R8. Rumors pegged the trusty 4.2 as a dead engine revving, thanks to Audi's newer 4.0-liter twin-turbocharged V8 found in models like the S6 and S7.
We expected the 4.0-liter to be the go-to engine in the next R8, but according to Car and Driver, there have been some issues cooling the force-induced mill in the mid-engine R8. The issues are so severe, in fact, that the 4.2 is going to be retained in the car's second generation.
It's more than just practical matters like cooling that are keeping the R8 from going turbocharged. C/D reports that even with the current state of forced induction, a turbocharged R8's throttle response and its resultant exhaust note would suffer too much to be feasible.

Audi A3 E-Tron could launch in October in US

When we test drove the Audi A3 E-Tron plug-in hybrid in Europe last summer, Audi was talking about the vehicle's introduction in the US, but left the exact date up in the air. Summer or Fall 2015 was as specific as anyone was willing to get. Now it looks like the plug-in will arrive in October. One of the rumors we heard over the last few months was that the A3 E-Tron was not ready for the US because of poor cold-weather performance. From what we've heard, under a certain temperature limit, the engine needs to kick in at all times, no matter what the battery state of charge is, and some European A3 E-Tron owners are disappointed that their EV sometimes isn't all that electric. Audi's solution needs to take into consideration how to balance utilization of battery power in less-than-optimal temperature ranges with passenger comfort and how any excess battery use impacts longevity. Audi's "fairly conservative" position will "ensure the long-term credibility of the E-Tron platform and plug-in technology." - Brad Stertz Brad Stertz, the corporate communications manager for Audi of America, told AutoblogGreen that, "Audi is taking a fairly conservative position to ensure the long-term credibility of the E-Tron platform and plug-in technology, while still creating the best experience for our drivers in each region. Overall, I think it is safe to say low temps affect performance in all vehicles to some degree, but that plug-ins face unique challenges that we will continue to work through with the A3 e-tron and other plug-in models to follow." Stertz also said in April that the US configuration for the A3 E-Tron was still being fine-tuned. For example, there were some software differences under consideration to meet US driving preferences. Looks like we only have four more months to wait and see. Related Video:
