It includes a 354-hp, direct-injection version of the 4.2-liter V-8 found in the S4 sedan, and knocks a full second off the zero-to-62 mph run.
The S5 has an even more aggressive sports suspension, bigger brakes, and unique exterior treatments that include aluminum-look mirrors, dual exhausts with four oval tailpipes, a rear deck spoiler, and different front and rear fascias. It rides on eighteen-inch wheels with 245/40-18 S-Design wheels, and includes the Xenon Plus headlight package (with those sexy LED daytime running lights). Inside, it has a sport wheel and sport seats, a grey instrument cluster, aluminum door sills, and special dash inlays.
