my bet is that there isn't any synchronization between the diesel engine driven wheels and the electric motor driven wheels. consider that the attack weighs around 1,900 lbs. a lotus elise weighs 2,000 lbs., has 190 hp and goes 0-60 in 4.7's. the hybrid attack is supposed to go 0-60 in 4's. they don't say 4.0 seconds. so it's probably somewhere near the mid 4's range, which could be accomplished by the 200 hp electric motor alone in the attack depending on gearing, etc. the diesel engine is rated at 100 hp. so it's not necessarily even running during the 0-60 runs. the electric motor is supposed to use some form of capacitors to deliver maximum power for a very short period of time. in other words, a few quick starts and back to the garage to get charged. it's not clear to me whether the vehicle runs on either or both power plants at a given time.
