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.

Scion was slain by Toyota, not the Great Recession

Scion didn't have to go down like this. Through the magic of hindsight and hubris, it's easier to see what went wrong. And what might have been. What the industry should understand is this: Scion wasn't a losing proposition from the get-go. Its death is due to negligence and apathy. This is more than just the failure of a sub-brand. It's the failure of a company to deliver new and compelling products over an extended period of time. Toyota will point to the Great Recession as the reason it hedged its bets and withdrew funding for new vehicles, instead of using that as an opportunity to redouble efforts. This was as good as a death warrant, although myopically no one realized it at the time. Sadly, GM's Saturn experiment was a road map for this exact form of failure. No one at Toyota seemed to think the Saturn experience was worth protecting their experimental brand from. Or they weren't heard. Brands live and die on product. Somehow, Scion convinced itself that its real success metric was a youthful demographic of buyers. It seems like this was used to gauge the overall health of the brand. Look at the aging and uncompetitive tC, which Scion proudly noted had a 29-year-old average buyer. That fails to take into account its lack of curb appeal and flagging sales. Who cares if the declining number of people buying your cars are younger? Toyota is going to kill the tC thirteen years [And two indifferent generations ... - Ed.] after it was introduced. In that time, Honda has come out with three entirely new generations of the Civic. Scion wasn't a losing proposition from the get-go. Its death is due to negligence and apathy. At launch, the brand could have gone a few different ways. The xB was plucky, interesting, and useful – a tough mix of ephemeral characteristics – but the xA didn't offer much except a thin veneer of self-consciously applied attitude. That's ok; it was cute. Enter the tC, which managed to combine sporty pretensions with decent cost. It took on the Civic Coupe in the contest for coolness, and usually managed to win. More importantly, an explicit brand value early on was a desire to avoid second generations of any of its models, promising a continually evolving and fresh lineup. At this point, the road splits. Down one lane lies the Scion that could have been. After a short but reasonable product lifecycle, it would have renewed the entire lineup.

Scion was Toyota's lost generation

Toyota's top North American leader was succinct in explaining the reasons for killing Scion. "It's the right decision at the right time," Jim Lentz said. It's hard to disagree. In a strong market that saw 17.5 million sales last year, Scion volume dipped three percent. Its product lineup has withered for years, which is always a telltale sign a brand doesn't have the full support of its owner. Though enthusiasts love the FR-S sports car, it's the fruit of a joint project with Subaru that also produced the BRZ. Scion's coolest car has a twin sold by one of its rivals. After the FR-S launched in 2012, Scion got nothing – squat – in the way of new products until the iA and iM arrived late last year, IHS senior analyst Stephanie Brinley noted. "[Scion] was not successful in building a visual brand identity or product personality," she said. Lentz, Scion's first vice president and now CEO of Toyota's North American division, admitted the market has changed. "Younger customers have a different mindset," he said. In the early oughts, a brand that catered to a youthful demographic made some sense, and this is one front where Toyota can declare victory. Seventy percent of Scion's buyers were new to Toyota, and the average age was 36 years old. The problem is, not enough of them buy Scions anymore. Scion hit a highwater sales mark of 173,034 vehicles in 2006 and hasn't come close to reaching that since. The recession hurt Scion, too. It bottomed out in 2010 with just 45,678 sales, a time when the rest of the industry was beginning to recover. There was a brief uptick (73,507) in 2012, but Scion failed to capitalize on that momentum and sales fell for three more years. Toyota is calling Scion's pending death a "transition" back to the main company. Sure, most of the cars will be rebadged Toyotas, like the FR-S, iA, and iM. The C-HR, an attractive future crossover that would have given Scion a boost, will go into production as a Toyota. But make no mistake: This is a failure. Toyota is closing a brand in the same way General Motors scrapped Oldsmobile, Ford shuttered Mercury, and Chrysler dropped Plymouth. Those brands languished for years. Toyota moved quicker to put the fork in Scion, which prevented it from becoming a long-term drain on the parent company. Lentz was dead on. It's the right time.
