BMW has updated the entire 4 Series lineup with a new look, a more upscale cabin, and a revised suspension. So far, the changes have only been announced for the Euro-spec model.

It takes a well-trained eye to tell the updated 4 Series apart from the outgoing model. Visually, all variants of the 4 come standard with bi-LED headlights and LED fog lights up front. Select models also receive a redesigned bumper with a thin strip of chrome trim that emphasizes the 4's width.

The back end features LED tail lamps and chrome trim on the bumper. Finally, buyers can choose from four new alloy wheel designs and two new additions to the color palette named Snapper Rocks Blue and Sunset Orange, respectively.

Equally minor, the changes made to the interior are largely limited to new trim elements, additional upholstery colors, and double-stitching on the dashboard. An upgraded sports steering wheel and an available digital instrument cluster round out the updates.

Some of the modifications are invisible to the naked eye. Notably, engineers managed to make the 4's suspension stiffer without making the ride harsher.

There are no major mechanical modifications to report. The base 430i carries on with a 248-horsepower, turbocharged 2.0-liter four-cylinder engine, while the 440i gets a 3.0-liter straight-six rated at 320 horses.

An eight-speed automatic transmission and rear-wheel drive come standard. A six-speed manual transmission is offered as a no-cost option, and buyers can pay extra for BMW's xDrive all-wheel drive system.

The updated BMW 4 Series will go on sale in the coming months. Pricing information hasn't been released yet.
