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.

Tier 1 suppliers call GM the worst OEM to work with

Among automakers with a big US presence, General Motors is the worst to work for, according to a new survey from Tier 1 automotive suppliers, conducted by Planning Perspectives, Inc.
The Detroit-based manufacturer, which has been under fire following the ignition switch recall and its accompanying scandal, finished behind six other automakers with big US manufacturing operations. Suppliers had issues with trust and communications, as well as intellectual property protection. GM was also the least likely to allow suppliers to raise their prices in the face of unexpected increases in material cost, all of which contributed to 55 percent of suppliers saying their relationship with GM was "poor to very poor."
GM's cross-town competitors didn't fare much better. Chrysler finished in fifth place, ahead of GM and behind Dearborn-based Ford, which was passed for third place this year by Nissan. Toyota took the top marks, while Honda captured second place.

First 2014 Toyota Corolla commercial dances through time

Despite the fact that the Toyota Corolla pretty much sells itself, the eleventh-generation 2014 model is getting a huge marketing push that aims to appeal to both Millennials (of course), as well as the older generations that have lived with the stalwart Japanese compact for decades. The first television advertising spot, called, "Style Never Goes Out of Style," shows that the Corolla has had a place in mainstream culture since its launch in the 1960s. We have to admit, it's pretty cool to see older models from the '60s, '70s and '80s come out to play for this commercial, especially the latter of those, as it gives us enthusiasts fond memories of the infamous AE86.
The whole web/broadcast/print/social media marketing campaign surrounding the 2014 Corolla is called "Elevate," because, according to Toyota:
Extensive market research shows that Millennials are looking to take their career to the next level and are looking to buy their first 'real' car to get them there. The design of the all-new Corolla is significantly elevated from the previous generations, creating a more dynamic and desirable image for the Corolla nameplate that will appeal to these younger buyers.
