Via EE Times: Following the introduction of its first electric car,
startup Tesla Motors on Jan. 8 dropped hints about a next-generation
sports sedan for the 2009 time frame. The car will boast the equivalent of
110 miles per gallon and will continue to use off-the-shelf lithium ion
batteries.
According to Winding Road the sedan is said to take on the BMW 5-Series,
the rear-drive vehicle will be sold globally, with a more ambitious volume
target of 10,000-20,000 units per year. The as-yet-unnamed second model
will likely ride on a chassis made of lightweight steel. The sports sedan
will cost between $50,000 and $75,000 and have room for five adults and a
full-sized trunk.
The electric car startup is also looking to manufacturer the sedan in the
United States and is seeking a new round of venture capital funding.
Last year, the company introduced its first electric car, the Tesla
Roadster, shown in photo. The roadster boasts the equivalent of 135 miles
per gallon and a range of 250 miles on a single charge.
That means there is the equivalent of (250mi)/(135mi/gal) = 1.82 gal of
gasoline on board. If you replaced the power train with a gasoline
version and a 15gal fuel tank, your range would then be
(15gal)*(135mi/gal) = 2025 miles, less whatever regen benefit the battery
might provide. Assuming regen of a very generous 25% would still be 1500
mile range.
I think there might be a bit of bogosity in their numbers.
