|ML 320 CDI vs. Rx 400h
The German car magazine Auto Bild has conducted a comparative test drive from New York to San Francisco with a new Mercedes-Benz ML 320 CDI diesel and a Lexus RX 400h hybrid.
Combined results for the test drive, which although it combined city and highway driving obviously emphasized the highway, had the Mercedes diesel besting the Lexus hybrid by 10% in terms of fuel consumption.
Average total consumption for the Mercedes over the 5,200-kilometer trip (3,232 miles) was 9.2 l/100km (25.6 mpg), while the Lexus came in at 10.2 l/100km (23 mpg).
The hybrid drive performed better in city driving. The diesel is ten times worse with respect to NOx emissions.
The ML 320 CDI uses the new Mercedes 3-liter V-6 powerplant. The engine, with an output of 165 kW (224 hp) and a maximum torque of 510 Nm (376 lb-ft), increases output and torque up to more than 30% while maintaining fuel consumption at the level of its predecessors and meets Euro-4 emissions limits.
