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.

Consumer Reports says infotainment systems 'growing first-year reliability plague'

The Consumer Reports Annual Auto Reliability Survey (right) is out, and the top two spots look much the same as last year's list with Lexus and Toyota in first and second place, respectively. However, there are some major shakeups for 2014, with Acura plunging eight spots from third in 2013 to 11th this year, and Mazda replaces it on the lowest step of the podium. Honda and Audi round out the top five. This year's list includes six Japanese brands in the top 10, two Europeans, one America and one Korean.
Acura isn't the only one taking a tumble, though. Infiniti is the biggest loser this year by dropping 14 spots to 20th place. Other big losses come from Mercedes-Benz with an 11-place fall to 24th, and GMC, which declines 10 positions to 19th.
Perhaps unsurprisingly, it's not traditional mechanical bugs hauling down these automaker's reliability scores. Instead, pesky problems with infotainment systems are taking a series toll on the rankings. According to Consumer Reports, complaints about "in-car electronics" were the most grumbled about element in new cars. Problem areas included things like unresponsive touchscreens, issues pairing phones and multi-use controllers that refused to work right.

Toyota reveals new TS040 Hybrid LMP1 [w/videos, poll]

There's a new season of motor racing upon us, and while that doesn't always mean a new crop of cars in every series, in the case of the 2014 FIA World Endurance Championship, that's exactly what it means. Porsche recently revealed its new 919 Hybrid and Audi its revised R18 E-Tron Quattro. Now it's Toyota's turn.
Revealed today at the Paul Ricard test track in the South of France, the new TS040 Hybrid is based on the TS030 Hybrid it replaces, redesigned to meet the latest regulations established by the FIA and ACO for the World Endurance Championship and its flagship race, the 24 Hours of Le Mans. In accordance with said regulations, the TS040 is two inches narrower than the TS030 and also incorporates a new hybrid powertrain.
The previous 3.4-liter V8 has been replaced by a 3.7-liter V8 developing 513 horsepower, and the new engine is coupled to an Aisin AW electric motor at the front, a Denso electric motor at the rear and a Nisshinbo super-capacitor that combine to kick out an extra 473 hp, giving the system a combined output of nearly 1,000 horsepower while consuming 25 percent less fuel than last year's car. It also gives the TS040 all-wheel drive to help channel all that power to the road.
