Honda has just introduced the all-new 2010 Honda Insight hybrid in Detroit. The five-door car gets 40 mpg in the city, and 43 mpg on the highway.

Honda's all-new 2010 Honda Insight hybrid steals a bit of the spotlight at the North American International Auto Show. The new Insight, revealed in Detroit earlier today, gets 40 mpg city and 43 mpg highway.

Based on the Honda FCX Clarity concept, the five-door sedan is meant to evoke an "advanced and aerodynamic" shape. It utilizes Honda's Integrated Motor Assist system to switch between battery power and a 1.3-liter SOHC aluminum alloy i-VTEC petrol engine. Kinetic energy is captured from braking and deceleration, and stored in the compact battery under the rear floor. The battery can be used to exclusively power the car in low and mid speeds. The two systems combine for a 400 mile range.

Features include an ECON mode activated by the driver. When turned on, settings for the automatic CVT, engine, and powertrain are all tweeked to be more fuel efficient. Also, feedback is constantly fed to the driver through a speedo display, letting the driver know what he can do to increase fuel economy. These are all part of the Ecological Drive Assist System, or "Eco Assist."

Safety measures for the five passegers include six airbags, ABS with electronic brake distribution, and front head restraints. Crash protection is improved by the Advanced Compatibility Engineering system (ACETM), where the body moulds to the shape of a striking vehicle. Folding rear seats, climate control, and an MP3/CD audio set-up are also included.

The EX trim line comes with alloys, cruise control, a premium stereo system with a USB input, paddle shifters, and Sat-Nav.

The 2010 Honda Insight goes on sale in the U.S. starting April 2009. Exact pricing has not been announced, but base price will be below the $23,650 Honda Civic Hybrid.
