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.

2015 Audi A3 E-Tron [w/video]

Over the years, we've had a chance to test a lot of Audi E-Tron vehicles, from very early all-electric prototypes (back then we only got to sit in the passenger seat) to the A6 L E-Tron PHEV and the A1 E-Tron plug-in hybrid. All of them were concepts and promises, merely whispers of what was possible, even as the Nissan Leaf, Chevrolet Volt and two Tesla models were making waves in the marketplace.
As we learned last year in our Deep Dive of the E-Tron project, all of the concepts, prototypes and rumors have finally come to fruition in this A3 Sportback E-Tron. Previously, we were given a chance to drive a prototype, but it was only very briefly. Last week, we finally got to run a production-representative example through the hilly roads between Vienna, Austria and Munich, Germany. After spending a solid day with Audi's first marketable E-Tron vehicle, we can say that it's a most amazing bit of engineering, in particular for the way that Audi has done so much to hide the fact that this is an electrified vehicle. Not entirely, of course, but the idea was to make the A3 Sportback E-Tron a no-compromise PHEV. And that means it drives and feels, in many ways, like the standard A3 Sportback despite over 700 extra pounds. Oh, and there's a charge port hidden behind the four rings in the grille.

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:
