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.

Porsche wins the 2015 24 Hours of Le Mans

The question going into this year's 24 Hours of Le Mans was whether or not the Porsche 919 Hybrid would be able to combine its qualifying pace with race reliability. After battling neck-and-neck with Audi's R18 for most of the race, the answer is a resounding yes. Not only did Porsche drivers climb the first two spots on the podium, they did so without any major mishaps on track. This win is the first overall trophy for Porsche since 1998. Audi previously won the last five races, and 13 of the last 15. Corvette also returned to the winner's circle, with the No. 64 C7.R taking winning the GTE Pro division. The victory is the first class win for Corvette since 2011. KCMG won the LMP2 class in ninth overall. With 45 minutes to go the No. 98 Aston Martin crashed out of first place in GTE Amateur, giving the class win to SMP Racing's Ferrari and second place to the Patrick Dempsey Racing Porsche 911 RSR. For the full list of official results, click here. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. For most of the race, the battle at the top went back and forth between the two German manufacturers. An tire puncture in the No. 7 Audi gave up the lead to Porsche, and moments later a crash forced the No. 8 into the garage. But a three-minute replacement of the front and rear bodywork kept the Audi in contention. As the race wore into the night, Porsche maintained a slightly faster pace than Audi. Nick Tandy took the lead on Lap 253 early Sunday morning, and car No. 19 never gave up the top position. The win is the first for all three drivers of the No. 19 – Nico Hulkenberg, Earl Bamber, and Nick Tandy. A lap behind in second was the No. 17 Porsche. The Audis fought reliability problems late in the race but still finished third with the No. 7 R18. The GTE Pro class proved to be just as exciting as the P1 class, with a four-way battle for first after four hours into the race. As the Aston Martin cars dropped away, the lone Corvette Racing entry took over, followed by a charging AF Corse team Ferrari 458 Italia. The Corvette and Ferrari continued to trade places in the final hours until gearbox trouble forced the No. 51 Ferrari out of contention. It was eventually passed by the other AF Corse car, No. 71. Nissan experienced all the pain of a first-year effort with its front-wheel-drive GT-R LM Nismo.

Recharge Wrap-up: Audi A4 TDI in US, Local Motors' 3D EV sales

Local Motors plans to begin selling its 3D-printed electric cars in 2016. The Arizona-based startup will begin by selling a neighborhood electric vehicle, called the Reload Redacted, in the first quarter of 2016, with a full-speed version to follow. The design for the car, submitted by Kevin Lo, was chosen by a panel from a pool of entries. The company plans to set up microfactories to build the cars at a fraction of the cost of setting up a traditional automotive manufacturing facility. Now, Local Motors is looking at ways to quicken the 3D-printing process, a task that currently takes days for a single vehicle. Read more at NBC News, or in a blog post from Local Motors.
