The S430 uses a 4.3 liter version, while the S500 offers up 5.0 liters. Both use a single camshaft on each cylinder head, along with three valves per cylinder. Depending on engine load, two plugs fire with a short time gap, at the same time alternating between the two for better combustion efficiencies and less noise. The S500 has 302 horsepower, which is down a bit from the last version, and 339 pound-feet of torque. Passing power is even better, with plenty of pull left well after the speed limit has been exceeded.
Traction control is standard.
