The Audi S-4 is powered by a newly-revamped three-liter TFSI V-6 direct-injection engine -- plus an exhaust turbo-charger. The engine has a power output of 260 kW -- and even at a relatively low 1370 RPM, can hit a maximum torque of 500 Newton-meters. The S-4 can go from zero to 100 km per hour in just 4.7 seconds -- and uses an average of 7.3 quarts of fuel per 100 kilometers.
