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.

Takata air bag recall list

The National Highway Traffic Safety Administration confirmed yesterday that 33.8 million vehicles with Takata airbags are going to be recalled. It's the largest recall in automotive history. The already record-breaking rate of automotive recalls this year shows no signs of slowing down, especially since millions of cars with defective airbags made by global supplier Takata are under ongoing scrutiny. The federal government is warning owners that inflator mechanisms in the air bags can rupture, causing metal fragments to fly out when the bags are deployed. The faulty air bags have already been blamed for multiple deaths. How do you know if your vehicle is safe? The National Highway Traffic Safety Administration released an updated list of vehicles under recall. Sometimes however, the government's website will crash and the list may not be complete. Check your VIN at the NHTSA website to make sure. The list of cars affected by the recall has not been released, but seem to span multiple models over the years for many of the automakers.

Fewest vehicles ever found eligible for Most American survey

Once again, the most American car on the market is from an American brand. The Ford F-150 retained its number one spot in Cars.com's annual survey of the most American vehicles, trumping the Toyota Camry, which remains at number two.
Ford taking the top spot is small consolation, though, as the Detroit Three aren't too well represented here. General Motors scored a win at number seven, with the Chevrolet Corvette, while Chrysler squeaked in at number ten, with the Dodge Viper. Outside of those three vehicles, Toyota and Honda dominate the top ten.
What's most remarkable, though, is that there were so few cars available for this year's list.
