Hyundai Prius-fighting hybrid spied wearing new camo

Hyundai's engineers certainly don't want the public to see its upcoming dedicated hybrid model in several of these new spy shots, but the company can't deny that the machine is on the way. These test cars were first spotted last summer as Prius-like five-door hatchbacks. However in these photos and the second set, it would seem that the model has morphed into a more sedan-like shape similar to the Chevy Volt. Unlike the last time we saw this car during arctic testing, the vehicle no longer is covered in plastic concealment. That obfuscation has been replaced with a very effective camo pattern on everything but the roof, and in several photos, workers are actively standing in the way of the spy shooters' lenses. Beyond the whole model's general shape, there are a few details to pick out, though. You can easily spot the outline of the brand's hexagonal grille up front. There appears to be a rather complicated air dam design there, too. In profile, the shape of the rear hatch creates an integrated spoiler at the back. While the camouflage makes it very hard to tell, we don't see a plug-in port on this example. According to our spies, this test car was being driven with a slew of other electrified models, including a BMW i3, Nissan Leaf, Volkswagen e-Golf, and Kia Soul EV. Given that group, perhaps the engineers were specifically benchmarking the electric performance for this outing. Earlier reports suggest that Hyundai's latest hybrid could debut in the second half of 2016. Power reportedly comes from a 1.6-liter four-cylinder with hybrid assistance and a lithium-ion battery. Plug-in and five-door hatchback versions are also rumored.

Toyota FT-1 hints at Supra, more aggressive hybrids

Toyota showed off the new FT-1 performance concept at the 2014 Detroit Auto Show today, and the obvious story angle is that this is the new Supra. That's enough weight for most concept cars to carry, but then we thought about it a bit more - FT-1 stands for "Future Toyota 1," after all - and re-read the hints Toyota is dropping about how the FT-1 fits into the company's future. Put all the pieces together, and we think there's a chance Toyota's hybrid models are about to get a whole lot cooler. Technically, the FT-1 is an EV, but that's just because all it has for a powetrain is a small battery and motor to move it around on stage. This concept doesn't even have a proposed powertrain, but a production Supra could have any number of powerplants under the hood (V6, V8, hybrid and inline-six are all mentioned by Automotive News). We also like the big red start button on the steering wheel, which owes at least a little to the blue start button in the Prius. What we're more interested here is what this sleek red beast could do for the look of Toyota's hybrids. The FT-1 could change how Toyota designs cars in the future. To make the FT-1, Akio Toyoda, the president and CEO of Toyota Motor Corporation, apparently challenged Toyota's Calty Design Research team to create a car with passion and "a palpable heart-pounding sense of excitement." Instead of making design decisions "by consensus among a large group of stakeholders," the company says "the [design] approval process has been streamlined. This new approach aims to produce cars that connect more deeply with customers." There was a sense in Detroit today that the FT-1 heralds a change in how the company designs cars in the future. The FT-1 is apparently not the result of Toyota's hybrid supercar partnership with BMW, but we know that Toyota isn't a total stranger to a high-performance hybrid category, having built the TS030 hybrid Le Mans race car. For an on-road gas-electric from the company, though, we're much more used to the egg-shaped Prius. While Toyota has backed off a 2003 pledge to make every model a hybrid, it has said that it wants gas-electrics powertrains to proliferate throughout the line-up. And, if the FT-1 previews a new Toyota look, then at least some of those hybrids will benefit from some of the good looks on display in Detroit.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
