Prior to the revealing of the SL400, the cheapest SL-Class on the market was the $106,900 SL550, which featured a 429-horsepower, 4.7-liter, biturbo engine. Apparently wanting to spread its flagship roadster to more buyers, the SL400 offers the look and feel of the SL550 but with a V-6 engine and a much lower price point. So, how low did Mercedes go with this new model?
Mercedes actually cut over $20,000 from the SL550’s price tag, placing the SL400 at a cheaper-than-expected $84,000. For this cash, you get a 3.0-liter, biturbo engine with 329 ponies, a 5.1-second 0-to-60 run, a seven-speed auto transmission with paddle shifters, a panoramic moonroof, 18-inch twin-five-spoke wheels, wood or aluminum trim, a start/stop system, ground effects, 16-way power and heated seats, Homelink, and a Harman/Kardon LOGIC7 audio system with an 80 GB hard drive, Bluetooth audio streaming and SiriusXM.
With the SL400, buyers can also opt for a trio of packages. The Premium 1 Package adds in things like a rearview camera, PARKTRONIC, ventilated and massaging seats, KEYLESS-GO, and an electric trunk closer for $4,900. The Sport Wheel Package adds in 19-inch AMG wheels, a sport brake system and a sports steering wheel for $2,000. Finally, the Driver Assistance Package adds in DISTRONIC PLUS, PRE-SAFE braking, active blind-spot assist and active lane-keeping assist all for $2,950.
With the 3.0-liter engine, the SL400 received EPA ratings of 20 mpg city, 27 mpg highway and 23 mpg combined, which is a nice bump over the SL550’s 17 mpg city, 24 mpg highway and 20 mpg combined ratings.
With this new SL400, Mercedes gives buyers a nice gap-filler between the SLK350 and the SL550, plus it gives buyers that want the larger and more luxurious SL-Class without a fire-breathing, gas-guzzling V-8 under its hood.
