230 horsepower and 242 lb-ft of torque. Given its light-for-an-SUV curb weight of 1,760 kg (3,880 lb), the 4WD V6 Highlander is reasonably powered, with crisp acceleration off the line and adequate passing performance in all circumstances. Toyota placed an emphasis on ensuring the Highlander's drivetrain would be as smooth and refined as that propelling the Camry. They reduced noise, vibration and harshness (NVH) by the use of sound-absorbing and vibration-damping materials. And on V6-equipped models, specially engineered Active Control Engine

Mounts cancel-out engine vibration during idle. It's this type of attention to mechanical function that imparts a sense of quality in the Highlander's operation beyond what I have experienced in some competing brands. Toyota's penchant for driveline smoothness extends to the Highlander's five-speed automatic transmission as well, which only comes bolted to the V6. The 2.4-litre I-4 engine, which I have not yet tested, produces 160 horsepower and arrives connected to a four-speed autobox. The five-speed transmission makes very efficient use of the V6 power, but I found on occasion it tried too hard to be smooth, resulting in protracted first-to-second gear upshifts under nominal acceleration.
