GM Sequel fuel-cell vehicle will be a Chevy
Filed under: Hydrogen, Chevrolet, GM

General Motors announced today that their all-wheel drive fuel-cell vehicle the Sequel will wear the Chevrolet brand. The news was first reported by Winding Road, and that site will report back from the first test drive of the prototypes tomorrow. The decision to make the Sequel a Chevy (instead of, say a Cadillac or Saab) should help make fuel cells seem more accessible to the majority of car buyers. GM has invited a small number of journalists to test drive the Sequel, and an AutoblogGreen blogger is one of them. Look for his report soon. Until then, click through the jump for more images of the Sequel and GM's press release.

GM REINVENTS THE AUTOMOBILE: CHEVROLET SEQUEL IS A BETTER, CLEANER, PETROLEUM-FREE SOLUTION
SAN DIEGO – General Motors today allowed journalists to drive the most technologically advanced automobile ever built – the Chevrolet Sequel, GM's solution to provide the world with a cleaner, petroleum-free vehicle that is better in nearly every way.
"General Motors is proving that advanced technology can remove the automobile from the environmental debate and reduce our dependence on petroleum," said Larry Burns, GM vice president, research & development and strategic planning. "Chevy Sequel clearly shows that our vision for the future of the automobile is real and sustainable."
Chevrolet Sequel fuel-cell vehicle
Sequel was introduced in 2005 at the North American International Auto Show in Detroit. It is the first vehicle in the world to successfully integrate a hydrogen fuel cell propulsion system with a broad menu of advanced technologies such as steer-and brake-by-wire controls, wheel hub motors, lithium-ion batteries and a lightweight aluminum structure. It uses clean, renewable hydrogen as a fuel and emits only water vapor.
"Sequel fundamentally changes the DNA of today's automobiles ... exchanging an internal combustion engine, petroleum and mechanical systems for fuel cell propulsion, hydrogen and electrical systems," Burns said. "In Sequel, GM has created a real vehicle that promises to excite customers and lead to long-term, sustainable automotive transportation."

Compared to other fuel cell vehicles, Sequel has an unprecedented range of 300 miles between fill-ups and spirited acceleration, attaining 60 mph in just 10 seconds. Sequel also has all the amenities one would expect in a premium, five-passenger crossover SUV, including impressive styling, a spacious interior and an all-aluminum body and structure designed to meet all applicable Federal Motor Vehicle Safety Standards. It has a low-profile, skateboard-like chassis that houses all of its main propulsion, braking and chassis components.
"Sequel is a vehicle that is better in nearly every way – quicker, more sure-footed, easier to handle, easier to build and better looking, while being safe and emitting only water vapor," said Burns.
Other benefits include:
- Unequaled control on snow and ice, or uneven terrain
- 70-percent more torque for unparalleled acceleration
- Shorter braking distances
- Ability to "talk" to other vehicles about traffic congestion or road conditions

"Four years ago, our chairman and CEO, Rick Wagoner, challenged us to completely rethink the automobile," Burns said. "With the Chevy Sequel, we have now met Rick's challenge by reinventing the automobile and making it real. We've proven a new DNA for vehicles that is viable for the future."

The Good: Decent performance, 300 mile driving range in a full-sized car (something not quite achievable yet with batteries). Clean and Quiet. Can be quickly refilled with hydrogen at a station when taking a long trip — if you could find a hydrogen station, which you can’t.
The Bad: Still tied to filling stations. Hydrogen is reputed to be much less energy efficient than batteries, depending on how the hydrogen is generated. It’s still only a prototype, and we don’t get any indication of when they might be mass-produced or how much they might cost. And. . . I personally wouldn’t feel highly confident driving around with three large 10,000 PSI tanks of anything underneath me. If those rupture, you’d be in orbit.

"It uses clean, renewable hydrogen as a fuel and emits only water vapor."
Nearly ALL of current commercial hydrogen production is from methane conversion. That's because using a FOSSIL FUEL for the conversion is nearly an order of magnitude cheaper than electrolysis of water.
Using hydrogen to power a car is insanely stupid. And the fact that it is nowhere near green in any meaningful sense is only one of many reasons.

Looks like a real first step to hydrogen/fuel cell cars. Alternate sources of hydrogen will come around when there is a demand.
2920 lb-ft torque at the wheels???!!!

Howard, did a hydrogen truck hit your grandma as well? Seriously, what do you propose, we walk everywhere?
The hydrogen infrastructure is in its mere infancy. Don't you think there will be more efficient (and green) ways of producing hydrogen once more research is done?
Seriously, what’s with all of the “this [enter any alternative energy source] is insanely stupid” crap?

How can anyone say that a fuel cell is less efficient than batteries when one produces and the other stores, we are talking about two totally different processes here. Personally I can't wait for them to become the norm.
