Japan Used Audi RS4 for Sale

The Audi RS4 quattro is the top tier and highest performing version of some specific generations of the Audi A4 range of automobiles. It is a sports-focused compact executive car (often called sport compact citation needed in some countries which), produced by Audi's high-performance private subsidiary Audi Sport GmbH, in limited numbers, for German car manufacturer AUDI AG, part of the larger Volkswagen Group. The 2018 RS4 is 0.6sec quicker than its predecessor from 0-62mph, at 4.1sec (two tenths slower than the lighter RS5) and tops out at 174mph.  

The RS4 Avant manages about 450 horsepower and 443 lb.-ft. of torque shuffled to all four wheels via an eight-speed automatic gearbox. Sixty miles per hour comes in just about four seconds, and the top speed is capped at 155 mph but can be de-restricted from the factory to reach 174 mph. The engine has increased crankcase breathing, a low-pressure fuel return system and a baffled oil sump, to prevent engine lubricant cavitation at high engine speeds and high-G cornering. It has four valves per cylinder (instead of five on the earlier variant) and two overhead camshafts on each cylinder bank (so it is 'quad cam') and these are driven by roller chains with variable valve timing for both inlet and exhaust camshafts, along with a cast magnesium alloy fixed tract length intake manifold with adjustable tumble flaps (to improve low engine speed combustion).
