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.

An early gas-electric hybrid was developed by...Exxon?

We're not sure which aspect of Exxon's 1970s-era efforts to develop advanced and electrified powertrains is the most ironic. There's Exxon, that of the Valdez oil spill infamy, being on the leading edge of hybrids and electric vehicles. There's a boat-like Chrysler Cordova getting 27 miles per gallon. And there's the central role a Volkswagen diesel engine plays in that hybrid development. It's all outlined in an article (linked above) by Inside Climate News, and it's an amusing read. Flush with cash and fearing what it thought was peak oil production in the 1970s, Exxon funded a host of new ventures divisions geared to find alternatives to gas-powered powertrains. In the early 1970s, Exxon lured chemist M. Stanley Whittingham to develop what would become a prototype of a lithium-ion rechargeable battery. Then, in the late 1970s, Exxon pioneered the concept of using an alternating-current (AC) motor as part of a gas-electric hybrid vehicle. The company retrofitted a Chrysler Cordova (yes, that's the model Ricardo Montalban used to hawk) with a powertrain that combined 10 Sears Die-Hard car batteries, an alternating current synthesizer (ACS), a 100-horsepower AC motor, and, yes, a four-cylinder 50-horsepower Volkswagen diesel engine. The result was a rather large two-door sedan that got an impressive 27 mpg. And while US automakers didn't see the potential in the early concept, in 1980 Exxon and Toyota began collaborating on a project that would involve retrofitting a Toyota Cressida with a hybrid engine. That car was completed in 1981, and may have been one of the seeds that eventually helped sprout the concept of the Toyota Prius. Soon after rebuilding the Cressida, Exxon would get out of the advanced-powertrain-development business, as oil prices began to fall in the early 1980s, spurring cost-cutting measures. Cry no tears for the Exxon, though, as what's now known as ExxonMobil is the largest US oil company.

Audi investing $30.3 billion through 2018 for product expansion

How does Audi plan to reach two million units in annual sales and pay for the 11 new models it's adding to its lineup - an expansion that may include models named SQ2, Q9 and F-Tron? By increasing its investment to 22 billion euros ($30.3 billion US) between now and 2018. That figure represents an increase of about 500 million euros over the previously planned outlay, according to a report by Automotive News, and that could be due to Audi wishing to goad the momentum that pushed it to 1.5 million annual sales two years ahead of schedule.
It's also about staving off the challenges from BMW and Mercedes-Benz. Now that BMW has been able to turn some of its attention away from its "i" series of Megacity cars, it will reportedly spend more than planned in 2014 as it continues the rollout of ten all-new vehicles and 15 new-generation vehicles through the end of next year. Mercedes, having been dropped to third in the sales race, is preparing to add 13 new cars over the next six years.
Audi's money is going into technology, into product like the next-generation TT and the Q1 and production expansions and upgrades all over the world. The expenditure represents just under a fourth of Volkswagen's 84.2 billion-euro ($115.7 US) outlay devoted to taking the number-one global automaker title away from General Motors and Toyota by 2018.
