BMW's 228i Convertible lounges in the Austin sun (pictures)

This is it: the 2015 BMW 228i Convertible.

This is the most affordable BMW drop-top, replacing the 1 Series.

It's a bit larger, but still has the same character -- despite its name going up by 100.

The interior is typical BMW quality, including a 6.5-inch display, and for the first time, wireless, over-the-air map updates for the navigation system.

With the top down, the rear profile is flush and taut.

Rear seat room is a bit tight, but manageable.

The car definitely looks its best with the top down.

BMW's shark nose is in effect, though in a refined form.

Trunk space is respectable for a convertible.

A 240-horsepower, 2.0-liter turbocharged four provides the power.

Our test car had the optional M Sport brake package, which adds blue calipers.

Fuel economy with the automatic is EPA rated at 24 city, 34 highway and 27 combined.

The top is fully powered and drops in 20 seconds. Here's a look at the procedure!

Front comes up...

Then the rear raises to match.

Folding begins.

More folding...

Tonneau cover raises to make room.

The whole thing starts to tuck into the trunk area.

The top can be dropped while moving, even at speeds of up to 30 mph!

Starting MSRP on the 228i Convertible is $38,850, but you'll probably be looking to spend a fair bit more with the many and varied options packages BMW offers.
