Someone who spends $100,000 on a 4 second 0-60 Tesla roadster is not looking to recoup the costs by saving fuel. If it helps your thinking, just assume they both have the same fuel economy.

I just did a 1100 mile trip in my 1997 MB E420 after doing some minor tuneups & fluid changes. She had 105k miles when I bought her, and I got 25.8 MPG doing 80-85MPH and hitting 110MPH a few times. Remarkable for a 9 year old M119 w/ 105k miles lugging 3800lb!!

About fuel efficiency there's something strange about Mercedes.

My 2005 SLK200K can do US MPG 36.2 / Imp MPG 43.5
The car before that, a 2002 C180 W203 could do 39.8 / Imp MPG 47.9
One of my old cars, a 1988 E200 W124 with a single two step carburettor and 15500 miles on the speedo could manage US MPG 47.3 / Imp MPG 56.8!

Where about engine developments? The newer car the more fuel they demands. When talking to Mercedes people about this they could not explain why.

even though engines are getting more advanced and more fuel-efficient, modern cars weigh a lot more b/c it needs to haul a lot more gadgets, gizmos, safety equipment and bigger wheels/tires.

Than if "money is no object" I would go for 2.5 sec Veyron

GM may revive the electric car

Automaker expects future success with technology of hybrids, batteries and hydrogen fuel cells.

David Shepardson / The Detroit News

WASHINGTON -- General Motors Corp. is likely to unveil a prototype plug-in hybrid at the North American International Auto Show in Detroit as part of its company-wide focus on "electrifying" the car, GM officials said Thursday.

The advanced technology vehicle would have an extended driving range on battery power alone and would also have a diesel or gasoline engine that could power the car when the battery was low.

Later this month, GM chairman and CEO Rick Wagoner will deliver a speech at the Los Angeles Auto Show in which he will disclose that the linchpin to the company's turnaround is its emphasis on advanced technologies.

Ultimately, GM sees hydrogen fuel cells as the solution to ending the country's reliance on oil. However GM believes the key is using electricity -- through hybrids, batteries and hydrogen fuel cells -- to run vehicles, not gasoline.

Again, lot of whining about the car, that nobody can see, even less drive.
My understanding is, that GM concept is putting small combustion engine for emergency use and not actually design to perform at freeway speed?
I see no problem to drop a generator in the trunk of electric car and recharge it if it runs slightly out of range. You know that those miniature aerodynamic cars need about 8 HP to push at 50 mph?
Than, do they have trunk big enough for 8 HP generator
