In certain parts of the world, buying into either the Mercedes-Benz S-Class range, or the BMW 7-Series range, means opting for a base diesel version.
In both cases, you'd be looking at 3.0-liter inline-six engines, producing 265 PS (261 HP) and 620 Nm (457 lb-ft) of torque in favor of the 7-Series, and 286 PS (282 HP) and 600 Nm (442 lb-ft) of torque in favor of the S-Class.
According to AutoTopNL, this race is between a 730d that gets from 0 to 100 km/h (62 mph) in 6.1 seconds and an S350d that needs just 5.8 seconds, which means it's actually the 4MATIC version.
Either way, the BMW 730d is the lighter car here, regardless of whether or not the S350d is wearing its heavy, yet useful all-wheel drive suit. Now, while there are slight differences to observe, you'll find that these two models are remarkably similar when it comes to accelerating in a straight line.
So whichever one you may be driving, we reckon it should handle various workloads just as well as its rival.
