Valentin Technologies has given the public its first glimpse of its IngoCar, currently in development. The vehicle's estimated mileage is 170 mpg based on a mix of city and rural driving. This extraordinary fuel efficiency is achieved by a revolutionary hydraulic-fluid drive. This hybrid gasoline/hydraulic drive system can deliver acceleration from 0-60 in 4 seconds. Using a small engine, fluid is pumped into an accumulator. The fluid then drives hydraulic wheel motors for shiftless acceleration. During braking, motors are reversed and pump the entire recuperated braking energy back into the accumulator. This innovative technology and the car's light weight give an estimated range of 1,000 miles for a full 6 gallon tank of fuel.
