New Honda hybrid systems target three different vehicle types
Honda Motor Company has announced the development of a new Sports Hybrid Intelligent Dual Clutch Drive system. The company has three different version of the Sport Hybrid system to accommodate different vehicle characteristics.
The new one-motor Sport Hybrid Intelligent Dual Clutch Drive system is optimized for small-sized vehicles. Honda has a two-motor hybrid system called the Sport Hybrid Intelligent Multi-Mode Drive that is optimized for medium-sized vehicles. The third Sport Hybrid system is called the Sport Hybrid SH-AWD that features three motors. That last system is optimized for large vehicles and has been tipped for the new
The one-motor system uses a newly developed in-line four-cylinder 1.5-liter Atkinson cycle engine mated with a seven-speed dual clutch transmission. The hybrid system also uses a high-output lithium-ion battery and promises to improve efficiency by over 30% compared to conventional one-motor systems.

The two-motor system will be first used in the

and uses a lockup clutch and lithium-ion battery pack. The system will offer three different profiles depending on the driving situation, including EV Drive for electric only use, Engine Drive for medium to high-speed cruising, and Hybrid Drive for urban driving conditions.
The three-motor system combines a V6 engine and a high-output three-motor electrical system providing acceleration performance equivalent to that of a V-8 engine. The big benefit with this system is that despite the V-8 performance, fuel efficiency is reportedly better than that of an in-line four-cylinder.

The system will be mated with a 3.5-liter V6 engine and a seven-speed DCT transmission with its own built-in motor. The system uses independent motors for the right and left rear wheels with positive torque applied to the outside wheel and negative torque applied to the inside wheel allowing for independent control of torque distribution. The system is designed to help improve cornering performance – this makes the NSX the perfect application for such technology.

Also, the ride wasn't all that good. It's been years since I've been in it. But ride and handling were mediocre. The regenerative braking was poorly balanced with the conventional friction, and made the brake pedal feel like mushy garbage until you actually pushed hard enough to get the pads to start clamping down on the rotors.
They gave him a can of fix-a-flat as a spare, too. Did I mention it felt like a tin can, at titanium can prices?
