The 2017 SL450 forms the starting lineup of MB’s SL class roadsters. Under the hood of the SL450 is a 362 hp, 3.0 litre, V6, twin turbocharged engine that can fire as many as four times in one millisecond. Technologies such as high-pressure direct injection with ultrafine fuel spray, diecast alloy block, and widely variable valve timing make it a smooth, powerful and highly efficient engine. MB’s robust 9-speed automatic transmission with shift paddles now also comes as standard on the SL450.
To add to the driving pleasure MB has provided a multimode drive program selector on the console. A rotary knob lets the driver choose from four modes, ‘eco’, ‘comfort’, ‘sport’ and ‘sport+’. Each mode adjusts the car’s throttle response, shift points, steering settings and other performance characteristics. There is also a customizable ‘individual’ mode to allow for purely manual shifting. A sport exhaust system with polished chrome tailpipes produces rich notes. US retail prices start at $86,950.
