The faster luxury sedan in this test is also the more fuel efficient one!

It’s the battle of the limousines! While these luxury sedans are packed to the brim with features, they do not compromise on the performance part at all either. In fact, the Mercedes-Benz S350d and the BMW 730Ld that we tested pack enough firepower to even put some sports cars to shame. But how do the two luxury juggernauts fare against each other? We put both through a series of tests and here are the results.

Before we head out for the real world let’s read the paperwork first.

The 7 Series is slightly faster to the ton and will be quicker by a tenth of a second under kickdown from 20kmph when you’re overtaking. BMW’s eager steptronic transmission plays a huge part in its victory on this front. The BMW doesn’t stop there as it is also the frugal one out of the two, even if the difference is a marginal half a kilometre to a litre whether it’s out on the highway or negotiating city traffic. These are no drastic differences but a win is a win and it’s the 7-Series that draws first blood.

It goes without saying that both the cars are fitted with advanced braking setups. The ‘S’ is fitted with ventilated disc brakes upfront and solid discs at rear while the ‘7’ gets solid disc brakes on all wheels. But it’s still the BMW that takes top honours here. The numbers suggest that the 730Ld is as fast in dropping anchor as it is in gathering pace.
