Ultra-Efficient Hybrid Electric Vehicle: 200mpg+ http://lkcl.net/ev

The Goal: to create an affordable light-weight ultra-efficient 3-seat Hybrid Electric Vehicle from mass-produced off-the-shelf parts and recyclable materials.

Why is this car needed?

Thanks to "Peak Oil", we know for a fact that the cost of fuel is set to rise. Therefore, this vehicle is to be designed to charge from on-grid or off-grid 240 volt mains, as well as have a standard off-the-shelf 240 volt 5kW Diesel Generator on board, to continuously recharge the battery. Journeys of up to 1000 miles will only use around 5 gallons of Diesel, Bio-Diesel or other compatible Bio-fuel (WVO).

Traditional vehicles are designed to be mass-produced to a highly-optimised profitable degree, using sub-optimal cheaper parts or sacrificing energy-saving features that would greatly benefit the vehicle's owner, all in the name of maximising profits. There is an alternative approach: to design the vehicle to be lighter, use less materials, use recyclable materials, and easy to assemble, to the extent where the vehicle can be cost competitive and affordable, even and especially if manufactured locally.

The vehicle also needs to be energy-efficient to run, as well as easy to maintain: this is achieved by reducing weight as well as air resistance losses. At only 350kg (1/3 the weight of a Supermini), the weight is low enough that there is less stress and friction on every moving part, from the motor to the tyres. Hills are easier to climb. Acceleration is relatively quick, even though the motor (which weighs only 20kg not 150kg) is 8 times "less powerful" than the one in a standard family car. The key however is the bodywork, which has been designed around a streamlined core. Yet, at the same time the vehicle is padded out to give the appearance of being larger than it really is. This is for social acceptance as well as for Road Safety reasons: traditional streamlined vehicles are far narrower than standard vehicles.

Surely, someone has designed one of these vehicles already?

Nobody in the world has ever made a long-range ultra-efficient light-weight 3-seat Hybrid! Incredibly, after evaluating dozens of Hybrids and EVs, from Mass-volume manufacturers, well-known prominent Car Designers and even EV enthusiasts, absolutely nobody has combined all of the features present in this vehicle into one package.
