Where to watch and follow the 24 Hours of Le Mans this year

In less than 24 hours the flag will drop on Audi's title defense at the 24 Hours of Le Mans, Toyota's best ever chance to win and Porsche's return to le grand defi. The Le Mans organizers have kept as au courant with broadcast options as they have with power unit technology, so you'll be able to find a place to watch or listen no matter what your preferred method. Friend-of-Autoblog Reilly Brennan has again put together an exhaustive "couch kit" of viewing options, which you can check out at his site. Here's the short list: Le Mans Site Le Mans TV Le Mans Facebook page Le Mans Twitter page FIA WEC Live timing Audi Sport stream Corvette Racing stream Nissan NISMO stream Entry list and grid Spotter's Guide You can watch or listen to the excellent Radio Le Mans, app, Autosport will have hourly updates and a live blog, the ACO has a Le Mans app. Fox will broadcast the event over a combination of Fox Sports 1, 2 and its Fox Sports Go App from 8:30 EST Saturday morning until 9:30 am EST Monday morning. Hit up Reilly Brennan's site for even more options and details like Eurosport and Daily Motion, and good watching – this should be a spectacular race.

Toyota R&D shows off free piston engine linear generator for future EVs

We often hear how an electric vehicle powertrain architecture allows vehicle designers much more freedom than a traditional ICE powertrain does. With differently shaped battery modules and small electric motors, there are lots of way to put the pieces together. With today's plug-in hybrid technology, engineers still need to put a decent-sized ICE somewhere, but new technology from Toyota could free up the gas-electric vehicle designers of the future. Presented at the recent SAE World Congress in Detroit, the idea from Toyota Central R&D Labs Inc. and involves what is called a Free Piston Engine Linear Generator (FPEG). Think of it as a sort of one-cylinder, two-stroke mini-engine that can work either as a generator (thank to magnets and a linear coil) or to directly drive a vehicle. The current prototype is a 10-kW unit that Toyota say would provide enough power to get a B- or C-segment electric vehicle up to highway speeds (75 miles per hour) when paired up to offer 20 kW. Pairing the FPEGs is also important to minimize vibrations. One system tested by Toyota had a 42 percent thermal efficiency, but the engineers are working to improve the overall efficiency even further. You can watch an animated video of the piston in action here (click on "Outline") and see the SAE papers here and here. More technical details are available at Green Car Congress.

Toyota 86 most likely to get more power through more displacement? [w/poll]

The Sydney Morning Herald has spoken to Tetsuya Tada, chief engineer of the Toyota 86 (our version of it, the Scion FR-S, is pictured above), and they've been promised that more power is on the way. We've heard a lot of speculation about a more powerful Toyobaru since before the standard model was even launched. The only question now is how the power will be delivered, and among the engine concepts we've already heard about - turbo, supercharger, twin-charged, hybrid - is a new one: more displacement.
Tada said that an engine with more displacement than the current coupe's 2.0 liters is being tested alongside a turbocharged and a hybrid-assisted motor. The SMH cites "inside sources" as saying the displacement option is the one likely to get the go-ahead, and suggests increased bore and stroke will see the engine grow to 2.5 liters, horsepower to about 250 - a 50-hp increase over the present car.
While that's apparently the betting man's solution for the long-awaited increase in gumption, what happens with the next generation could be more wide open than we suspected. According to the report, Tada "hinted that [a successor] could be a radically different car, potentially dropping the boxer engine altogether." He said once they've sorted out the concept for the second generation car, then they'll sort out an engine. That's where a turbo option could come to market, perhaps the turbocharged four-cylinder Toyota is developing for the Lexus NX crossover or a hybrid system that uses a capacitor.
