Peaking at 295 horsepower, a V6 gas engine drives the 2021 Lexus RX 350. Combustion in this 3.5 L engine is controlled by the signature VVT-iW function. The base trim gets up to 268 pound-feet of torque from the normally aspirated powertrain. However, the RX 350L edition extracts slightly less output from this six-cylinder propulsion system. Engineered to deliver eight gear combinations, the Electronically Controlled Transmission guarantees a dynamic drive. Carrying the Dynamic Torque Control label, an all-wheel drive works in tandem with the ECT. Thanks to a locking differential, the rear wheels are less likely to slip on a wet road. Designed to dissipate heat from the gearbox and engine quickly, an oil-based cooling system is optional for both Lexus crossover SUVs.
