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.

2017 Scion FR-S getting slight power bump?

A common refrain when discussing the Scion FR-S and its sibling the Subaru BRZ is that they are capable vehicles but are in need of more power. The latest rumors suggest that some more muscle might finally be on the way for the coupe's refresh. Don't expect something like the STI Performance Concept with a 300-horsepower, turbocharged flat-four, though – the gains in the real world are likely to be significantly more modest. According to Toyota insiders speaking with Motoring in Australia, the local Toyota GT86 (our FR-S) is due for a styling and powertrain refresh for the next model year. The 2.0-liter boxer four-cylinder engine isn't expected to get a drastic power increase, but it's not being completely neglected. A new intake manifold and friction reductions reportedly allow for five percent more grunt. If accurate, and if the changes also come here, that would take output of the US version to 210 hp and 159 pound-feet of torque. The adjustments could improve fuel economy by seven percent, as well. Handling is already a forte for the FR-S and BRZ, and things could get even better with this refresh. Motoring claims that dampers from Sachs might become standard equipment, along with a reinforced subframe. The close relationship with the BRZ reportedly rules out any dramatic changes to the styling for this update. However, the coupe is still likely to wear a new hood with vents in it, reshaped headlights, and a revised fascia with a larger lower grille. At the rear, expect a rear diffuser and exhaust pipes at the corners. While minor compared to all of these rumored updates, Scion recently gave the FR-S a few tweaks in the US for the 2016 model year (pictured above). In addition to some new colors and interior trim, it now comes standard with a seven-inch touchscreen infotainment system and rearview camera.
