"That impressive fuel economy figure isn't just the result of the new engine – a suite of new pieces have been developed in order to maximize performance, including a revised air intake, a pair of new six-speed transmissions (both automatic and manual), electric power steering, and even some aerodynamic tidying, including a revised front fascia, deeper front air dam, rear-wheel tire spats, different underbody shields, and a new rear decklid seal."
