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.

GM, Ford, Honda winners in 'Car Wars' study as industry growth continues

General Motors' plans to aggressively refresh its product lineup will pay off in the next four years with strong market share and sales, according to an influential report released Tuesday. Ford, Honda, and FCA are all poised to show similar gains as the auto industry is expected to remain healthy through the rest of the decade. The Bank of America Merrill Lynch study, called Car Wars, analyzes automakers' future product plans for the next four model years. By 2020, 88 percent of GM's sales will come from newly launched products, which puts it slightly ahead of Ford's 86-percent estimate. Honda (85 percent) and FCA (84 percent) follow. The industry average is 81 percent. Toyota checks in just below the industry average at 79 percent, with Nissan trailing at 76 percent. Car Wars' premise is: automakers that continually launch new products are in a better position to grow sales and market share, while companies that roll out lightly updated models are vulnerable to shifting consumer tastes. Though Detroit and Honda grade out well in the study, many major automakers are clumped together, which means large market-share swings are less likely in the coming years. Bank of America Merrill Lynch predicts the industry will top out with 20 million sales in 2018 and then taper off, perhaps as much as 30 percent by 2026. Not surprisingly, trucks, sport utility vehicles and crossovers will be the key battlefield in the next few years, Car Wars says. FCA will launch a critical salvo in 2018 with a new Ram 1500, followed by new generations of the Chevy Silverado and GMC Sierra in 2019, and then Ford's F-150 for 2020, according to the study. Bank of America Merrill Lynch analyst John Murphy said the GM trucks could be pulled ahead even earlier to 2018, prompting Ford to respond. "This focus on crossovers and trucks is a great thing for the industry," Murphy said. Cars Wars looks at Korean (76 percent replacement rate) and European companies more vaguely (70 percent), but argues their slower product cadence and lineups with fewer trucks puts them in weaker positions than their competitors through 2020.

Toyota TRD Pro Chase Trucks are ready to hit the desert at SEMA

Toyota marks the 35th anniversary of its Toyota Racing Development performance arm this year, and the division is celebrating at this year's SEMA Show with a quartet of tuned off-roaders based on on the 4Runner, Tacoma and Tundra that look more than ready to go just about anywhere.
All four of them will take part in this year's Baja 1000 race, but only the Tundra (far left in the above photo) is actually competing. The other three will be there to act as support vehicles.
Inspired by the production TRD Pro Series trucks, the 4Runner, Tacoma and Tundra are prepared by off-road fabricator N-Fab with a mix of TRD and the company's own parts to be able to take whatever the grueling, 1,000-mile can throw at them. The trio is fettled with extra communications equipment, GPS, additional lights and all sorts of body and suspension modifications to help them survive the ordeal.
