Seeking ever-greater efficiency from its midsize crossover line, Mercedes-Benz has replaced last year's V8-powered ML550 with the ML400, which carries a turbocharged V6 engine. Everything else that draws buyers to the M-Class -- luxury, capability, refinement -- continues in full force.
What's New for 2015
The ML400 is a new addition to the existing M-Class, which is otherwise unchanged this year.
Choosing Your Mercedes-Benz ML400
The new turbocharged 3-liter V6 lays down 329 horsepower and 354 pound-feet of torque. While output is down versus last year's V8 model, the loss of performance in real-world driving is slight. Fuel economy now stands at 20 mpg in combined driving, a commendable figure for an all-wheel drive vehicle of this substance. As before, a seven-speed automatic transmission comes standard.
The five-passenger interior offers 38 cubic feet of space behind the rear seat, and a generous 80 cubic feet when it's folded. Leather upholstery is standard, along with heated front seats, driver memory, wood trim, a power-adjustable steering wheel, ambient lighting, and heated and cooled cupholders.
On the infotainment side of things, you get a 13-speaker Harman Kardon sound system, digital audio storage, and a navigation system with real-time traffic data. Safe sailing is assured courtesy of a rearview camera, blind spot monitoring and lane departure warning (adaptive cruise control with automatic braking can be added at extra cost). Other standards include a power liftgate, a sunroof, and power-folding and auto-dimming mirrors. The ML400 rolls on 19- or 20-inch AMG wheels, and additional AMG styling details are available.
- Nappa leather sport seats and a sport steering wheel come with the Sport Interior package.
- The Parking Assist package offers front and rear parking sensors, automated parallel parking and a surround-view camera system.
- Weekend warriors will appreciate the On/Off-Road package, which includes a six-mode terrain selector, skid plates, low-range gearing and an adaptive air suspension. The latter is also available separately.
There's certainly no shortage of specialized options for the ML400. You can choose from tempting features like a 14-speaker Bang & Olufsen BeoSound system, a panoramic sunroof, massaging and ventilated front seats, a split-view dash display and a rear entertainment system.
Even though it carries a V6, the ML400 is otherwise equipped like a line-topping model. Indulge in options if you like, but the base ML400 needs nothing extra to qualify as a high-luxury crossover.
