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 MR2 shows why we still love the 1990s

Was there a better time for Japanese performance than the 1980s and 1990s? It seems like looking back, Japan was on a roll, producing cars that were affordable, economical, reliable, fast and lightweight. And while all the attention is - thanks to a certain film series - focused on cars like Toyota Supra and Mazda RX-7, there is a lesser-known model that's establishing its own enduring legacy without the help of Paul Walker and Vin Diesel.
The MR2, affectionately known as the "Mister Two" to fanboys, first arrived in 1984 as a lightweight, mid-engined sports car that proceeded to eat the lunch of the Pontiac Fiero in terms of performance. That car was replaced in 1989 with the more familiar, rounded-out MR2, which is the subject of this latest video from the team at Petrolicious.
The video takes a look at a group of MR2 drivers, and attempts to explain what it is about the car that is destined to make it a future classic. Scroll down to see Petrolicious examine the MR2 Connection.

Sports 800 is a progenitor of Toyota performance

There's an automotive axiom that claims it's more fun to drive a slow car fast, than a fast car slow. If that's the case, then pushing a Toyota Sports 800 around must be one of the most exhilarating experiences behind the wheel in the world. With just 800cc of displacement from a two-cylinder boxer engine, the focus is on finesse over outright speed. Still, it's a fantastic page in Toyota's performance history, and Petrolicious takes a ride with a man who owns a meticulously restored 1967 example in its latest video.
The Sports 800 used the classic cost-saving strategy in the auto industry of taking parts from a standard model in the lineup and modifying it into a sports car. In this case that meant borrowing the engine from the plebian Toyota Publica, beefing it up for more power and clothing the whole thing a in beautifully shaped, wind-tunnel-honed body.
The look of these lithe, targa roadsters is the exact opposite of the rather dull styling sometimes associated with Toyota today. Everywhere you look there are louvers, vents or curves to draw the eye. Check out the latest Petrolicious video for a detailed look at the history of this rare model that's largely unknown on this side of the Pacific.
