Detroit auto show: Cars of the future

The LF-A convertible concept is powered by the same 500-plus horsepower V10 engine that powered the original LF-A concept shown at the 2005 Detroit Auto Show.

With these vehicles, Lexus wants to show the potential of the brand's new "F" line of performance vehicles.

"The first LF-A was a pure concept, but one that we went so far as to conduct engineering analysis on," said Bob Carter, head of Toyota's Lexus division. "This latest concept is much closer to a vehicle that we would bring to market, and one in which we will be gauging consumer interest."
