Next Audi RS4 to get an electric turbo?

We don't yet know if the next Audi RS4 will come to the US, but whoever gets it could find an electric turbocharger under the hood according to a report in Auto Express. The 4.2-liter V8 that has served for two RS4 generations is retiring from the line, replaced by a twin-turbocharged version of the supercharged 3.0-liter V6 used in the S4. But instead of using two sequential turbochargers - a smaller one to eliminate lag while a larger, more powerful turbo spools up - batteries charged by brake regeneration could power a first-stage electric turbo. The idea hasn't been publicly appointed for a particular model, as Audi's technical chief Ulrich Hackerberg has said that due to expense, that kind of setup "would only be used be used on the very top end models." Since the technology cuts down on the use of exhaust gases, it would also also help in markets like Europe where CO2 emissions are a factor. No matter whether it benefits from all conventional or some electric boost, the horsepower number for the twin-turbo V6 will be more than 420 hp but less than 503 hp, the rating of the V8-powered Mercedes-Benz C63 AMG. Auto Express believes Audi will want to maintain the power gap between the 333-hp S4 and previous, 444-hp RS4. With Hackenberg saying the new S4 will make more than 350 hp, that gets the coming RS4 up to at least 461, but AE figures it "could deliver as much as 480 hp." We'll find out sometime after the S4 launches next year.

Autoblog editors choose their favorite racecars of all time

If you like cars, there is a good chance that you like racecars. There's something about the science and the art of going faster, of competition, of achievement, that accelerates the hearts of enthusiasts. It doesn't matter the series, the team or the manufacturer – there's something about racing that stirs emotions and lifts spirits. It's that way with many of you, and it's that way with our editors. With that in mind, we offer a list of our favorite racecars of all time. Of course, we'd like to hear some of yours in the comment section below. 1970 Porsche 917 Compared to some of the obscure choices by my colleagues, I feel like the Porsche 917 is almost so obvious a pick as to not be worth mentioning. Still, when coming up with my answer, my mind invariably went back to this classic racer – specifically in its blue-and-orange Gulf livery – while watching Le Mans on DVD and later Blu Ray with my dad. Long, low and curvaceous, few vehicles have ever looked sexier lapping a track than the 917. More than just a pretty face, this beauty had speed, too, thanks to several tunes of flat-12 engines over the course of its racing life. In the early '70s, Porsche was a dominant force throughout sports-car competition, and the 917 (shown above at the 1970 24 Hours of Daytona) was the tip of that spear, including back-to-back victories in the 24 Hours of Le Mans. Largely without dialogue or really much of a traditional plot, Le Mans is like a tone poem of racing goodness. While the 917's importance to motorsports history is undoubtedly fascinating, it's still this cinematic depiction of the Porsche racer that draws me in most, especially with the volume cranked. – Chris Bruce Associate Editor 1964 Mini Cooper S How could everyone not be selecting the 1964 Mini Cooper S piloted by Paddy Hopkirk and Henry Liddon? That car, 33 EJB, took the first of British Motor Corporation's four Monte Carlo Rally wins (it should have been five, but French judges got the British Minis [and Fords] disqualified on a technicality regarding headlights... which its own car, the winning DS, was also in violation of). The tiny red car and its white roof beat out Ford Falcons, Mercedes-Benz 300SEs and scores of Volvos, Volkswagens and Saabs. This, along with the several years of dominance that followed, cemented the idea that not only could the tiny, two-tone Mini be a real performance vehicle, but that family-friendly city cars in general could be fun.

Tesla says Model 3 is best-selling midsize premium sedan in America

Auto sales figures are sort of fuzzy numbers, no matter how you slice them and no matter which manufacturer you're talking about. Unless you're specifically tracking vehicle registrations, automakers generally self-report the figures. So, you have to trust that they aren't doing anything too tricky. Plus, not every sale is equal, as some are logged as dealership loaners or demo models, some go to fleets (like to a rental car agency), and still others are, of course, bought by traditional customers looking for a new daily driver. With that preamble out of the way, when we saw a tweet from Tesla claiming that the all-electric Model 3 is the best-selling midsize premium sedan in America, our interest was piqued. According to Tesla, market share of the Model 3 has just surpassed the Mercedes-Benz C-Class, which had up until now led the Audi A4, BMW 3 Series, and Lexus IS as the best-selling sedan in its class. Note that the graph from Tesla below is, we think, specific to four-door models. So, is it true? Judging by the numbers we can find, including some from Bloomberg, which has a running chart to track Model 3 registrations, the answer is... probably. We don't know exactly how many Model 3 sedans Tesla is currently cranking out, but Bloomberg estimates production at about 2,560 units per week, and total sales for 2018 at 34,414. We know the number is increasing regularly, though, and Elon Musk has said most recently production sits around 500 units per day, which, on a seven-day cycle, would be 3,500 per week. We looked up Mercedes' sales figures for the month of May, 2018, and found that the German brand sold 5,419 C-Class models last month, for a total of 23,917 for the year (incidentally, that's down more than 30 percent from the year prior). While the bulk of those sales would surely be made up of sedans, it would also include a small percentage of coupes. Either way, it's likely that Tesla is currently producing and selling more Model 3s than Mercedes is C-Classes. Now, it's also worth considering if the C-Class is the only vehicle from Mercedes that directly competes with the Model 3. We'd guess customers may also cross-shop the CLA sedan with the Tesla, and if that's the case, you might decide it's worth adding in Mercedes' 2,527 CLA-Class sales last month and 9,622 so far for the year. The same argument could be made for certain versions of the BMW 2 and 4 Series.
