Toyota's hydrogen fuel cell Mirai isn't good enough to be a Lexus

It looks like the first hydrogen fuel-cell vehicle from Lexus will be faster than previously advertised, but it will get to the market slower than expected. It's all part of the paradox involved with Toyota looking to broaden its fuel-cell technology beyond the Mirai. Either way, the first Lexus fuel-cell vehicle is slated to start sales by the end of the decade, said Auto Express, citing comments from Alain Uyttenhoven, head of Lexus Europe. Uyttenhoven noted that it'd take an SUV to provide enough space to accommodate the packaging for the Lexus fuel cell powertrain. That comment may imply that the hydrogen-fueled powertrain from Lexus will offer similar performance to that of the Lexus RX450h hybrid SUV. That model delivers 300 horsepower and boasts a 0 to 60 mile-per-hour time of about seven seconds. Such a mill would be a departure from what we'd previously reported on Toyota's plans to expand its fuel-cell technology to its Lexus luxury badge. With Toyota believed to be planning to unveil as many as three fuel-cell models in time for the 2020 Summer Olympics in Tokyo, the Japanese automaker said early last year that it may have a Lexus fuel-cell vehicle available as soon as 2017, while reports suggesting the model would be a Lexus LS-based sedan. Additionally, the Mirai's fuel-cell powertrain had been believed to be the platform for the proposed Lexus fuel cell from the moment that model started sales in California last year. Apparently, though, the Mirai's 152-horsepower powertrain, coupled with a full-tank range that would be about 20 percent less than the 300-mile Mirai, isn't up to snuff for Lexus duty.

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.

2013 Toyota Avalon Hybrid

People, us included, make a big stink about the importance of family sedans. There's no doubt they're critical - they represent a huge slice of the market's annual sales and profits. However, despite accounting for far fewer transactions than the midsize sedan segment, the fullsize sedan is getting attention from manufacturers now that our market's entire lineup of those (slightly) smaller four-doors has turned over in the last two years or so. As most of the fullsize segment's mainstays derive a fair bit of their platform and powertrain technologies from their midsize cousins, these larger four-doors offer the potential for fatter profit margins, too. And with the newly stylish duds found on many of the industry's most successful midsize sedans, it's only right that automakers no longer think about fullsizers as big, squishy, vanilla family haulers with flat seats, vague steering and a thin layer of 'luxury' in the form of faux wood trim.
As manufacturers have again started diving into large sedans feet-first, the cars themselves have become sharper. The interiors are now of a higher quality and loaded with tech, while the exteriors have become further extensions of each manufacturer's design language. There's perhaps no greater example of this than the Chevrolet Impala and Ford Taurus, two models that evolved from subpar offerings into market leaders. This segment-wide transformation happened quite quickly, whether because of coincidental timing or because manufacturers are trying to get more out of their big cars, recognizing they account for a small portion of overall sales (just 3.5 percent of the new-car market in the first half of 2013).
The 2013 Toyota Avalon Hybrid is one such vehicle. We remarked on the changes to the V6 variant last year, and while we previously had a quick steer of the gas-electric hybrid, we figured the new model was worth a closer week-long look.
