The 2012 Mercedes-Benz S-Class is part of the vehicle's fifth generation. It is a luxury full-size sedan offered with several powerful engine options. The base S550 trim boasts a 4.7-liter V8 Biturbo that outputs 429 horsepower while the top-level S65 AMG carries a 6.0-liter V12 Biturbo delivering a staggering 621 horsepower. Both rear-wheel drive and 4MATIC all-wheel drive variants are available, all paired with a robust seven-speed automatic transmission. Despite the car’s performance-oriented nature, safety isn’t compromised, as it features Mercedes’ advanced PRE-SAFE system, Attention Assist, and a wealth of optional active safety measures like Distronic Plus adaptive cruise control. Inside, the S-Class spoils occupants with a COMAND system with navigation, Harman Kardon LOGIC7 sound system, and hand-polished wood trims. For the 2012 model year, a minor refresh gave the S-Class new engine options, improved fuel efficiency, and slight cosmetic tweaks.
