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.

NHTSA expands new Takata probe to 4 more automakers

DETROIT — The U.S. government's highway safety agency has launched an investigation into four additional automakers that have a potentially deadly type of Takata air bag inflator in their vehicles but have yet to recall them. The National Highway Traffic Safety Administration said in documents posted Thursday that it is investigating Audi, Toyota, Honda and Mitsubishi in connection with a Takata recall involving 1.4 million inflators. This brings the total number of manufacturers potentially impacted to five, as BMW was connected to the issue when it was brought to light earlier in December. The inflators made by the now-bankrupt Takata have a distinct and separate problem that can cause them to blow apart a metal canister and spew shrapnel into people's faces and bodies. The problem killed a driver in Australia who was in an older 3-Series BMW, which has already recalled more than 116,000 vehicles. The problem is so dangerous that in some cases BMW has told drivers to park their vehicles until repairs can be made. The safety agency says in documents that Takata didn't provide details on the affected makes, models or model years of vehicles with the defective inflators. So it is telling the companies to recall them promptly. The agency says that based on when the faulty inflators were produced, it's likely that the vehicles to be recalled came from the 1995 through 2000 model years. In letters to all four automakers, NHTSA says they have five business days to notify the agency after finding out about a safety defect. “If your company has not yet gathered enough evidence to make a determination that the subject air bag inflators present an unreasonable risk to motor vehicle safety, reply with a detailed work plan including the benchmark dates required to make the determination,” the agency wrote in letters to all four automakers dated Wednesday. A Honda spokesman said Thursday it hasn't determined yet whether its vehicles are affected, but a decision should be made soon. Audi, Mitsubishi and Toyota said they are still investigating. NHTSA has told the companies to respond by Jan. 17. On Dec. 4, NHTSA posted documents from Takata and BMW detailing the problems. The documents said the Australian driver was killed, while another Australian driver and a driver in Cyprus were injured. Unlike previous recalls, the Takata non-azide inflators do not use volatile ammonium nitrate to fill the air bags in a crash.

Incoming Toyota chairman wants a Supra successor

We'd venture to guess that in recent years, there have probably been almost as many rumors swirling about a Toyota Supra successor than there have been for a mid-engine Corvette. (Case in point: the speculative renderings we came across a few years ago, pictured above.) While we don't expect the Corvette's recipe to change drastically any time soon, it looks like a Supra - or more appropriately a Supra-like car - could be closer than we think.
First, there was an announcement of a BMW-Toyota joint venture. Said venture would, among other things, "Set up a feasibility study to define a joint platform concept for a mid-size sports vehicle."
Upping chances even further, a new Automotive News report claims that incoming Toyota chairman Takeshi Uchiyamada wants a vehicle "comparable" to the Supra. Clearly there are a lot of parties that want a new Supra to happen - to say nothing of enthusiasts - but Uchiyamada might be just the guy to get it done. None of this is proof positive of an impending Supra, to be sure, but winds do seem favorable.
