2011 Buick Regal
2011 Buick Regal flex-fuel badge
The best non-news of the day comes from Buick: the 2011 Buick Regal Turbo is flex-fuel capable, meaning it can run on either E85 or gasoline. We're not terribly excited (E85 still isn't all that common in most places), but we are looking forward to the first pure ethanol tune.
The E85 capability means that, with typical production-car overhead, the fuel injectors may have enough flow rate left over to handle pure ethanol. The fuel system should certainly be capable. And while big fat drag slicks on a wrong-wheel-drive car aren't that exciting, it could turn the Regal Turbo into a bit more of the car we wish it had been.
Buick hasn't announced any power or fuel efficiency figures for the Turbo when running on E85, but we'd expect output to remain about the same, and efficiency to drop by about 20-30 percent, as E85 contains less energy than pure gasoline (or the E10 we find in most pumps these days).
GM is calling the Regal Turbo the "first direct-injected turbocharged production car capable of running on any blend of gasoline or E85 ethanol," for whatever that's worth. Hit page two for the official announcement.
