Toyota FT-HS Hybrid Concept
Friday, January 19th, 2007
The Detroit auto show is held in a Las Vegas-like stage where carmakers do their best to amaze a world audience. Toyota will step up this year and show off its FT-HS Hybrid Sports Concept, a futuristic looking sports car that would be powered by a 400-horsepower hybrid powertrain. The Toyota FT-HS Hybrid Sports Concept is just that a concept, little more than a container for the overheated dreams of a bunch of designers at Calty Design Research. In fact, what you see here is only a two-dimensional animation, a computer-generated image of the show car that Toyota will be rolling out at the Detroit auto show.
“We feel there’s a hole in our lineup,” says Kevin Hunter, the vice president of Calty Design Research. “Toyota hasn’t had a sports car since the Supra was dropped in 1997. We need some emotional punch in our lineup, a halo product.” Toyota envisions that punch to be a rear-wheel-drive Hybrid Sports Concept (HSC) that develops 400 horsepower. “It’s a new kind of sports car for the 21st century,” adds Hunter. “Eco and emotion in a sports car concept with a performance target of 0-60 mph in about 4 seconds and a price tag in the mid-$30,000 range.”
A 3.5-liter V6 engine would deliver most of the thrust, and it doesn’t require too much brainpower to connect the dots to the DOHC 3.5-liter V6 in the Lexus GS 450h, which already makes 292 hp at 6,500 rpm. You wouldn’t have to look too far to find an electric motor to deliver the rest, because the water-cooled, 650V electric motor used in the GS 450h makes 197 hp at peak output, though this is just for seconds at a time.
The Calty designers, who have been working on the FT-HS for an entire year, are even willing to suggest that once the future arrives, a hybrid powertrain will be necessary to achieve the feeling of ultrahigh-performance that you want in a sports car. In a fuel-efficient future, a jolt of acceleration from an electric motor might become the equivalent of an injection of nitrous oxide into your gas-powered engine.
All this has overtones of ecological friendliness, of course, but as the buzz about global warming and greenhouse gases becomes a part of daily life, Calty’s designers remind us that a hybrid powertrain will have a certain quotient of respectability that you won’t find in a supercharged big-block V8. The FT-HS is even painted white because white is not only a pure motorsports color, but it’s clean which, Hunter tell us, supports the car’s hybrid message.
This is meant to be a 2+2-style car, large enough for occasional backseat passengers. We probably shouldn’t be surprised that it’s nearly as big as a Corvette, since it’s going to take a lot of space to package an engine, a fuel tank, an electric motor and a battery pack. The restrictive trunk volume of the Lexus GS 430h shows us just how difficult this task can be. The HSC’s long wheelbase should help balance the weight of the sizable battery pack that will be required. In fact, the HSC’s weight distribution might even approach the magic mean of 50-percent front/50-percent rear as a result.
The HSC has a hyperaggressive triangular profile, and this theme is repeated throughout the design. Meanwhile, much of the mass has been subtracted beneath the surface to create a shape that looks like an insect’s exoskeleton. Apparently the design has been inspired by the look of a downhill speed skier, in which individual aerodynamic elements are more important than overall streamlining. “Vibrant clarity is our new Toyota design language,” Hunter tells us. “And the car is packing plenty of J-Factor, which is the local and global acceptance of Japanese design.”
As envisioned by the Calty team, the engine will be visible through a hole in the hood to emphasize its hybrid nature. That dark portion in the middle of the hood is actually the engine cover poking through, much like a shaker hood scoop from the 1960s.
