Mazda-RX7

Mazda is calling this new rotary engine the "long-stroke rotary engine." As you may already know, the 13B rotary engine has a displacement of just 1300cc, which is 1.3 Liters. While the Mazda 16x has an engine displacement of 1600cc (800cc x 2), which is 1.6 Liters; and though they've made the 16x significantly larger than the 13B - it weighs less than a 13B. This is due to aluminum side housings, which Mazda says shouldn't scare us.
