There's adequate power under the hood -- a 3.5 liter 24 valve V6 engine with variable valve timing cranks out 270 hp and 251 lb-ft of torque, which is plenty for the 4090 lb RX to keep up with traffic and pass on the freeway. Power delivery is linear and predictable. The five-speed automatic transmission keeps the revs fairly low, and shift points are nearly undetectable.
