New look for critical new sedan

The seventh-generation BMW 3 Series has been spied once again, but this time our spy photography agency was able to get numerous detailed shots of the car's interior.

Although large sections of the interior are still covered, this set of photos gives us our best look yet at the cabin of BMW's signature model.

In front of the driver, at least in this and an earlier prototype, is a large customisable display with an integrated set of physical rings for the speedometer and tachometer.

At the recent Digital Day 2018, the company previewed some of the graphics it would employ on its latest generation of digital instruments.

In the centre of the dashboard, right above the interior's main vents, and in line with the instrument panel is a large trapezoid screen for the infotainment system.

Unlike Audi, BMW is sticking to physical controls for the climate control system, which are located underneath the central pair of air vents. Below those are shortcut controls for the infotainment system.

In the centre tunnel, there's the latest version of BMW's transmission lever, around which are controls for the iDrive system, driving modes, driver assistance features, and electronic parking brake.

As with every succeeding generation, the new 3 Series is expected to grow, which should benefit those riding within. Under the skin, the new 3 Series will ride on BMW's CLAR platform, which makes use of high-strength steel and other lightweight materials.

Motivation is expected to come from a selection of turbocharged three-, four- and six-cylinder petrol and diesel engines, with a plug-in hybrid also on the cards.

We don't know when the 3 Series will make its debut in production form, but it's unlikely to arrive in Australian showrooms before next year.
