There are two engines to choose from, a 3.5-litre V6, and a 5.5-litre V8. The 3.5 is smooth and composed, while the S500 uses Merc's all-new, 5.5-litre V8, with a wild 388bhp making for undignified performance from this cruise liner. 7G-Tronic trannny is also brilliant.
Massive number of driver aids means you could be dead and still drive it from Mumbai to Pune. It is also sportier than the last one, confident, and easy and helpful in town. Front or back, there is more than enough room. Features all kinds of adjustments, along with memorised seat positions and a steering wheel that swings out of your way when you are getting off.
The cabin architecture is radical in the best ways: uplifting and striking, full of lovingly crafted surprises with gorgeous feel. It won't let you crash that easily: it can brake by itself. If a crash is unavoidable, it'll tense the seatbelts and blow up a few airbags too. Expect huge bills, naturally. However, there's a better sales and service setup than its rivals. It actually is good value considering what you get: the Mercedes badge, the S-Class logo and limousine interiors are some of it.
