Mercedes-Benz S400d L 2018 review: snapshot

EXPERT RATING
8.5
The highest-spec diesel model in the refined Mercedes-Benz S-Class 2018 range is the S 400 d L - and it also happens to be the most affordable long-wheelbase variant in the mix.

The highest-spec diesel model in the refined Mercedes-Benz S-Class 2018 range is the S 400 d L - and it also happens to be the most affordable long-wheelbase variant in the mix.

It is priced at $222,500 plus on-road costs, and builds on the entry-level S 350d's extensive equipment list. 

Standard kit includes leather trim, heated and cooled front seats, nappa leather-wrapped steering wheel, great new LED headlights and a new interior ambient lighting system, a panoramic sunroof, head-up display, dark brown 'Eucalyptus' trim, auto-dimming rear-view and side mirrors, a wireless phone charging system, keyless entry and push-button start, auto-closing doors and an electric boot lid, too. 

And because it's the S 400 d L, you get electronically adjustable rear seats with memory function, side window blinds, a rear blind, rear climate control, and 20-inch wheels. 

The media system in the S 350 d includes sat nav with traffic monitoring, a 13-speaker Burmester sound system, digital TV, DAB+ digital radio, Apple CarPlay and Android Auto, and the 'Comand Online' system with internet capability.

Like the S 350 d, the S 400 d L is powered by a 2.9-litre in-line six-cylinder turbo-diesel that has been wicked up in this model. It churns out 250kW and 700Nm, and remains rear-drive with a nine-speed auto.
