Leaping upmarket, Jaguar rolled out a stunner penned by Ian Callum. The C-X16 (which will likely be called the XE when it comes to production) combines a supercharged V-6 with a hybrid designed to improve power. At the touch of a button, this Jag's electric motor supplies a 94-horsepower boost for 10 seconds; sort of like a nitrous bottle that never requires refilling. Far from gimmickry, hybrids are indeed coming to sports cars. Set to slot in below the XK in Jaguar’s sporting lineup, the XE’s designed to take on the BMW Z4 and Porsche’s Boxster/Cayman twins. The XE will likely keep the hybrid, if only to justify the "E" in its name.
