Hybrid cars are already some of the most fuel-efficient vehicles on the road, but is it possible to make one burn even less fuel? According to internet lore, building your own hybrid turbo is the key to unlocking even greater fuel efficiency. You know what the Motor MythBusters have to do now: Find a hybrid car (like this 2011 Honda CR-Z), bolt a turbocharger to it, and find out if forced induction can increase fuel efficiency.
The Motor MythBusters couldn’t be in better hands when it comes to making a hybrid turbo; Bisi Ezerioha bolts turbochargers to nearly any car imaginable (1,000-hp Honda Odyssey, anyone?) at his performance shop and consulting firm, Bisimoto Engineering. With the help of his Motor MythBusters co-hosts—Faye Hadley and Tory Belleci—the team should have no problem proving whether or not turbocharging a hybrid car can increase its fuel efficiency.
In the case of the Motor MythBusters hybrid turbo candidate, the 2011 Honda CR-Z has a flywheel electric motor sandwiched between its 1.5-liter inline-four cylinder gas engine and the transmission (six-speed manual or CVT, the Motor MythBusters have the manual). The electric motor is powered by a high-voltage DC system, separate from the rest of the CR-Z’s 12-volt electronics (your stereo and interior lights and stuff).
