The Kizashi EcoCharge concept aims to increase fuel efficiency by as much as 25 percent over the standard Kizashi Sport. It starts by reducing its gasoline engine displacement from 2.4 liters to 2.0 liters--a good first step, but it doesn't stop there. Next, Suzuki's engineers added a liquid-cooled induction electric motor/generator unit and lithium ion battery system to the mix, which contributes as much as 15 ponies to the EcoCharge's 144-horsepower, 127 pound-feet of torque output. Helping the hybrid to reach its 25 percent efficiency gain (coming to about 36 mpg hwy by our estimates) are other efficiency technologies such as engine start-stop, regenerative braking, and low-rolling resistance tires.
On the other end of the spectrum is the Kizashi Apex concept, which answers our prayers for a turbocharged variant. A Garrett turbo adding up to 8.5 psi of boost elevates the Apex's estimated output to the 275-300 horsepower range. Other go-fast goodies include an air-to-liquid intercooler, 19-inch wheels shod with sticky Yokohama tires, and a graphic scheme inspired by Suzuki's racing motorcycles. Okay, that last one doesn't actually help the Kizashi Apex go any faster, but even we have to admit that it's pretty cool.
