Acura revealed pricing and feature details about its new flagship sedan, the 2014 Acura RLX, at the Detroit Auto Show this week. The new luxury large sedan, which replaces the RL, will start at $48,450 when it hits dealerships in March.

In a press release, Acura says the RLX features an all-new V6 engine with direct injection that produces 310 horsepower. The base RLX is front-wheel drive, and Acura predicts that it will achieve EPA fuel economy ratings of 20/31 mpg city/highway. Acura also says the RLX is equipped with a system called Acura Precision All-Wheel Steer, which will aid maneuverability and handling by automatically adjusting the angle at which the rear wheels contact the road.

An all-wheel drive version of the RLX will go on sale later in the year. Acura calls its new AWD system Sport Hybrid Super Handling All-Wheel Drive. Kicking Tires explains that this system “uses an electric motor to power the rear wheels while the gasoline engine powers the front.” Acura says AWD versions of the RLX are rated at 370 horsepower. Acura says the AWD RLX should net an EPA-rated 30/30 mpg city/highway.

Acura says the RLX has a very spacious interior, particularly in the back seats. Car and Driver notes that one shortcoming of the previous RL sedan is that it was short on rear legroom. The publication says that the RLX’s longer wheelbase gives it “limo-like” rear-seat space.

In typical Acura fashion, the RLX features a host of technology features, including a cloud-based AcuraLink infotainment system with live traffic updates, an 8-inch navigation screen and a 7-inch multi-use display. A 10-speaker ELS stereo is standard, while one of two 14-speaker stereos is optional. It will also have USB connectivity, voice-command texting capability and other features like tri-zone climate control and a power sunroof. Available safety features include lane departure and forward collision warning, lane-keep assist, adaptive cruise control, a multi-view rear camera and parking sensors.

The RLX is priced more than rivals like the $42,870 Lincoln MKS, the $44,075 Cadillac XTS and even the $47,800 BMW 528i. However, it is more affordable than other rivals such as the $48,700 Infiniti M and the $51,000 Mercedes-Benz E-Class.

Rather than designated trim levels, the RLX will be available with four technology packages, with each one adding to the car’s interior features and luxury items. The most expensive package model, the RLX with advance package, is priced at $60,450.
