The twin-turbo direct-injection V8 motor in the best-selling GL450 is an outstanding combination of performance and efficiency. With 362 hp and 406 lb-ft of torque, it offers 27 hp and 67 lb-ft more than its predecessor. This added power and higher peak torque delivered over a wider rev range deliver all the prerequisites for relaxed long-distance cruising, as well as the versatility and responsiveness to deal with a wide variety of day-to-day activities.
At the top of the list, the GL550 now comes with a direct-injection twin-turbo 429 hp engine with a mighty 516 lb-ft of peak torque. While the extra 47 hp brings even more performance to this supremely refined full-size SUV, it is the added 125 lb-ft of peak torque that truly make themselves felt, in terms of off the line performance and the ability of the GL550 to handle heavy loads with ease. Alongside state-of-the-art engine technology, all three engines are equipped with extensive efficiency measures like direct-injection and paired with the new seven-speed automatic transmission. Intelligent alternator management keeps fuel consumption down, as does the electromechanical steering, the optimized belt drive with decoupler, the intelligent demand-based control of all auxiliary equipment and pumps. A key feature of the GL350 BlueTEC is also the SCR exhaust system optimized for airflow and back pressure.
