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.

YouTube's Super Bowl commercial buzz list dominated by automakers [w/videos]

After Sunday's big game, YouTube will be the place to watch every commercial that you missed when you left your seat for an emergency guac refill or, as we say in Cleveland, took the Browns to the Super Bowl. That makes YouTube the nation's water cooler on Monday, and it's got some preliminary stats to share in the lead up to kickoff.
As you know, Super Bowl advertisers, particularly automakers, like to endlessly tease their big budget commercials in the weeks before the game, many times revealing them outright days in advance. Because of this, YouTube can tell us which commercials have been viewed the most so far, and their top five list is all automakers.
Kaley Cuoco appears to have been a good investment for Toyota, as her ad for the RAV4 has garnered the most YouTube views - six million and counting - among Super Bowl commercials so far. Second place goes to Mercedes-Benz, though not its actual Super Bowl commercial, but rather the teaser for it. You know, the one with Kate Upton and the car washing, which is up to 5.6 million views. Third place is Audi's Prom commercial (3.3M views), fourth goes to Volkswagen's slightly controversial Get In, Get Happy ad (3.3M views), and the fifth and final spot is bookended by the teaser video for Kaley Cuoco's commercial (3.2M views). You can watch all five in order below.

2013 Toyota RAV4 earns 'poor' rating in IIHS small overlap crash test [w/video]

When the Insurance Institute for Highway Safety tested a batch of SUVs in its small overlap frontal crash test earlier this year, it held off on putting the Toyota RAV4 in the blender because the new, 2013 model was due to arrive shortly after the test. The new crossover might be better than it was before, but it could still only manage a rating of "Poor" in the test that has been a bugbear for a number of manufacturers.
Among other issues, the IIHS noted that the steering column moved seven inches to the right causing the crash test dummy to practically miss the airbag, the dummy's left foot was trapped in deformed sheetmetal and the dummy's head hit the instrument panel.
The 2013 RAV4 earned the Top Safety Pick rating by scoring well in the Institute's four other tests. A good score in this particular test would have earned it the Top Safety Pick+ rating that is so far only claimed by the 2014 Subaru Forester and 2013 Mitsubishi Outlander Sport in the SUV category. There's a press release below with more details and a video of the test.
