What would a Honda engine be without VTEC? It wouldn't be as efficient, for one, particularly if we're talking about VTEC-E, the latest spin on Honda's globally famous variable valve timing, in this case with a focus on economy over pure performance. Not surprisingly, the tiny triple runs on an extra-lean fuel to air mixture (of up to 25:1), thanks to a new air-fuel sensor, a rate that's nearly as high as direct-injection gasoline engines. To cope with emissions problems of running extra lean mixtures, Honda has come up with a very advanced catalytic converter, which captures the excess oxygen-rich exhaust wastes (NOx, etc.) when the car runs its lean cycle. It's then released during richer cycles to form less harmful emissions, thus retaining Honda's image as a super-green automobile manufacturer. Beyond 3,500 rpm - the upper bound of the super-lean running fuel to air mixture - the VTEC-E opens the second set of valves to create additional power for when the pedal hits the metal. On its own, the gasoline engine makes 67-horsepower and 66 lb-ft of torque, which is about on par with other inline-three engines sold elsewhere in the world.

Pop the ultra light, and oddly flexible hood open and you'll find the above-mentioned inline-three. The only indicator that there's anything out of the ordinary happening are some bright orange cords, a toy-sized battery and of course the silver and black IMA badge. Try as you like, you won't get a glimpse of the inner workings of the electrical components as Honda has chosen to stick the 10 kilo (22 lb) DC Brushless electric motor in between the engine and transmission. Rated at 10 Kw, it's the least powerful electric motor which Honda offers in a Hybrid powered vehicle, but considering the Insight's a featherweight, the 13-horsepower and 36 lb-ft of torque is more than plenty.

When called upon, the electric motor instantly and seamlessly kicks in, providing a constant electrical surge, made known to the driver only by a visual display on the dashboard. Unlike a turbo or supercharger, the electric motor's presence is nearly invisible - there's no whine or odd vibrations - you just go. Since the gasoline and electric motors have different peak power ratings, Honda has rated the Insight at 73-horsepower and 91 lb-ft of torque, which surprisingly is enough to spin the tires in first gear, leaving metre-long bicycle-sized treads on the ground, which are bound to confuse those who pay attention to skid marks on the street.
