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.

Weekly Recap: Toyota wants cars to be your 'close friends' around 2020

Toyota confirmed plans this week to launch autonomous technology in its production cars around 2020. The automaker's version is called Highway Teammate, and it's one element of a broader mobility strategy that includes vehicles communicating with each other and the grid. "Toyota believes that interactions between drivers and cars should mirror those between close friends who share a common purpose, sometimes watching over each other and sometimes helping each other out," the company said in a statement. That sounds utopian, and perhaps a bit cheesy, but it's an acknowledgment that autonomous driving requires more than technology developed in a vacuum. Toyota is looking at its research in a broader context, and dubs its overall strategy the Mobility Teammate Concept. Highway Teammate is the first step. Its test vehicle is a modified Lexus GS, which uses road-mapping data and external sensors to merge or exit highways, change lanes, and maintain safe distances during driving. It's operated on the Shuto Expressway in Tokyo. Toyota has been working on autonomous tech since the 1990s, with the goal of providing mobility for older people and the disabled, as well as lowering the frequency of traffic accidents. Toyota's push comes as an early adopter, Nissan, is hedging on its own deadline to implement the autonomous tech by 2020 due to a lack of firm laws governing self-driving cars around the world. Conversely, Volvo took the landmark step of being the first automaker to accept liability for when its cars will operate in autonomous mode, and urged the US government to set federal guidelines to regulate the technology. OTHER NEWS & NOTES 2016 BMW M4 GTS: Your water-injected, turbo-boosted demon BMW is unleashing its most powerful M4 ever, a 493-horsepower special edition that's road legal yet bred for the track. The company is making 700 copies for sale around the world, and 300 of them will come to the United States. The twin-turbocharged 3.0-liter six-cylinder revs to 7,600 rpm and uses a water-injection technology to cool the intake air and lower the compression temperature. BMW says this allows it to wring more power out of the inline six. The car also uses carbon-fiber reinforced plastic for the roof, hood, engine compartment strut brace, drive shaft, and rear spoiler to reduce weight. The M4 features BMW's organic light-emitting diode taillights, which are said to be an industry first.

Forza Horizon 3 car list keeps on truckin'

We've covered three weeks of car reveals for Forza Horizon 3, and this time we get a better look at the trucks, SUVs and other off-roaders you'll be able to use to explore Australia. This week's list kicks things off with two of the most legendary off-roaders in the world, the Toyota FJ40 Land Cruiser and the Meyers Manx. They have different purposes; the FJ40 is for tough trail work and the Manx is for some light-hearted beach fun. But no one could deny the cultural importance of either. And both should be a blast in Horizon 3. In addition to this pair of classics, players will have a chance to get behind the wheel of both a race version of the Ford F-150 Raptor and its closest rival, the Ram Runner. And when traditional vehicles start to get boring, why not take out a full-blown Baja racer such as the Penhall Cholla or the Rockstar energy drink version of the little Polaris RZR XP 1000 side-by-side? Forza Horizon 3 is shaping up to have one of the most diverse car lists in a racing game in a long time. There are still cars left to be revealed, so stay tuned for further installments and see this week's full list below. 1957 Chevrolet Bel Air 2002 Ferrari 575M Maranello 1992 Ford Escort RS Cosworth 2013 Ford Focus ST 1973 Ford Escort RS1600 1971 Ford Falcon XY GTHO Phase III 2014 Ford Fiesta ST 2017 Ford F-150 Raptor Race Truck 1954 Jaguar XK120 SE 2014 Jeep Grand Cherokee SRT 2012 Lamborghini Aventador LP700-4 1986 Lancia Delta S4 2009 Lexus IS F 1957 Maserati 300 S 1994 Mazda MX-5 Miata 1967 Mercedes-Benz 280 SL 2009 Mercedes-Benz SL 65 AMG Black Series 1971 Meyers Manx 2012 Mini John Cooper Works GP 1998 Nissan R390 1979 Opel Kadett C GT/E 2011 Penhall The Cholla 1971 Plymouth Cuda 426 Hemi 2015 Polaris RZR XP 1000 EPS Rockstar Edition 2013 Ram Runner 1993 Renault Clio Williams 1990 Subaru SVX 1979 Toyota FJ40 2005 TVR Sagaris 1990 Vauxhall Lotus Carlton Related Video: News Source: Playground Games / MicrosoftImage Credit: Playground Games / Microsoft Auto News Toys/Games Ford RAM Toyota forza exclusive ford f-150 raptor forza horizon forza horizon 3 toyota fj40 meyers manx
