First is the iChange. The iChange's design is a true low-slung sports car; it doesn't even have doors, passenger entrance by opening the glass roof-windows. So we all though it's powered by a gas-guzzling engine. However, the change in the iChange is that Rinspeed fitted it with a 175hp electric motor designed by Siemens, that can crack 60 mph in supercar speed 4 seconds, and will reach at 138 mph. No word yet on how many miles it could run before recharging, but it's definitely around 200 miles.
Second one from Rinspeed is the E2. Based on the Fiat-Abarth 500. So what Rinspeed did is fit a 60hp electric motor along the turbocharged 160hp 1.4L. However unlike any other hybrid car that combines the two engines together, Rinspeed gives the choice to the driver what the choose. In other words, in city driving, the driver pushes a "electric motor button" and only the 60hp electric motor works, and gets an equivalent of 90 mpg. When the driver fancy driving hard, the "turbocharged engine button" gives the driver Abarth's original 160 hp engine, that will do over 140 mph. So this E2 has two sides, the cuddly -light on fuel- side, and monster -fire up- side.
