2018 Mercedes-Benz SL 450 review: Our expert's take


What it is: The two-seat Mercedes-Benz SL-Class, a retractable-hardtop convertible, is constructed mostly of aluminum and equipped with a choice of V-6 or V-8 engines in luxury guise, and with V-8 or V-12 power in AMG performance models. The SL competes with the BMW 6 Series.


A backup camera and side mirrors that project the Mercedes-Benz logo are now standard.


AMG SL63, SL65


AMG performance versions of the SL-Class are available with a choice of power output. The SL63 uses a twin-turbocharged 5.5-liter V-8 engine that produces 577 horsepower and 664 pounds-feet of torque. The SL65 boasts a 621-hp, twin-turbo 6.0-liter V-12 engine that sends 738 pounds-feet of torque to the rear wheels. Both use a seven-speed automatic transmission. Mercedes says the SL65 can go from zero-to-60 mph in just 3.9 seconds. 



What's Special


  • Seven-speed automatic transmission with driver-initiated shift modes

  • AMG-specific LED daytime running lamps 

  • AMG rear spoiler 

  • Heated, ventilated and massaging seats

One minor issue that was addressed and resolved.

Great GT. Very comfortable. Excellent performance. Super good looking. Would buy again. Is the 3rd SL we've owned and, is likely, THE best one of all. Doesn't have that V8 sound but at $20K less in price, we'll accept that . . . in a heartbeat! I.e. 0-60 in 4.5 seconds and 107 MPH in the standing 1/4 mile is plenty quick enough!

5.0

Best car and best dealership ever!!!

This car is Fantastic! Stylish, comfortable, every possible safety feature, technologically advanced, fabulous sound system, and even a built in phone charger. The BRST car ever!!!

4.7

actually it's a 2017 with 9K miles

great combination of luxury and sportiness. drives like a 2 seat sports car when top down, or a comfortable sedan with top up. great acceleration for a 6 cyl. pricey but well worth it. fills a unique niche with little competition.
