2008 Detroit Auto Show: Saturn Flextreme Concept

• Looks like: GM built an aerodynamic Chevy Volt
• Defining characteristics: Wind-cheating shape, E-Flex electric drivetrain with diesel-powered generator
• Ridiculous features: Two Segways stowed under the cargo floor
• Chance of being mass-produced: E-Flex is well into production development, but what the cars will look like is anyone's guess

Like all Saturn production models except the Outlook, the Flextreme concept has a sister in Germany. Opel rolled out its version of the concept, under the same model name, at the Frankfurt Motor Show in September 2007. Both use a version of the E-Flex series-hybrid drivetrain introduced in last year's Chevy Volt. As in that concept, these are electric cars that run off a lithium-ion battery for up to 34 miles and are equipped with a generator to keep the car going up to 444 miles if the battery poops out. The difference is that the generator here is powered by a diesel rather than a gasoline engine. GM emphasizes that ethanol and fuel-cell versions will be part of the eventual offering.

A new and significant tidbit is Saturn's claim that the battery will recharge within three hours, where previously a vague "overnight" estimate was cited. The difference is consequential; any employer who offers electrical outlets in the parking lot effectively doubles the commuter's electric-only range. Someone who lives up to 30 miles from work theoretically could drive to and from work — and even bust out for lunch — without ever burning petroleum.

The Flextremes aren't merely sisters; they're twins. The badges are different, but they otherwise share the same look — that of a jelly bean with four hidden doors and cameras in lieu of side mirrors. It's not as interesting a shape as the Volt, but it's likely to avoid the aerodynamics shortcomings that have put the Chevy back on the drawing board. The rounded nose puts the headlight clusters and upper grille behind flush-fitting plastic windows, which cuts down on drag and, well, makes the grille not really a grille. GM says the crescent headlight shapes hint at the future look of Saturns — and Opels.

I understand the styling direction previews that of the next Opel/Vauxhall Zafira, which is a small 5 seat MPV in the vein of a Mazda 5. I wonder if that model will make it here as part of the next generation Astra line?

Hats off to GM for pushing the Chevrolet Volt and this Saturn Concept. Electricity for transportation costs the equivalent of dollar a gallon gasoline, and the money doesn't go to our enemies. Any type of vehicle can be a plug-in hybrid so we keep our diverse spectrum of vehicles, while becoming more self sufficent. Every electric mile driven in the city benefits air quality, and the electric grid is getting cleaner every day. It's too bad Ford didn't convert the Electric Ranger pickup built for the California market into a plug-in hybrid - they'd sell every one they could make.

This is what this country needs and employees should get on this as well. make it where the employee can pay for the electricity they use at work via pre-tax payroll deduction. i work 25 miles from my job and this looks sharp and is super practical.
