Is the BMW M240i Convertible a good car?

The BMW M240i Convertible is a drop-top version of the sporty M240i Coupe which is worth considering if you’re looking for something small, fast and fun but don’t like the sound of an Audi TT Roadster or a Porsche 718 Cayman.

Sure, the fairly unassuming BMW M240i Convertible doesn’t look quite as dramatic as these long-slung sports cars, but it comes with plenty of sporty features to help you tell it apart from the standard 2 Series Convertible. The front and rear bumpers are lower and more aggressive, you get some bigger alloy wheels and at the back, you’ll find a pair of larger exhaust pipes.

Step inside, and the BMW M240i Convertible doesn’t feel quite so special. Sure, everything feels just as well put together as in the super solid 2 Series, but it doesn’t look as sporty as the cabins in either the Audi TT Roadster or Porsche 718 Cayman and the higher seating position means you don’t feel quite so cocooned inside.

You do get plenty of equipment as standard though – including BMW’s excellent iDrive infotainment system with built-in satellite navigation – but you can’t get a digital driver’s display like in the TT Roadster which is a shame.

You do get a decent amount of seat adjustment as standard, though, and the BMW M240i Convertible comes with more supportive leather-trimmed sports seats than the standard 2 Series. Predictably, space in the back seats is no better than the standard car – two kids will have just enough space to get comfy but adults will feel pretty claustrophobic, especially with the roof up.

The BMW M240i Convertible is a more usable alternative to the likes of the two-seat Porsche 718 Cayman with a superb six-cylinder engine and a plush interior.

Having said that, the TT Roadster is even tighter in the back and the 718 Cayman doesn’t have any back seats at all. All three cars have similar-sized boots, though, so you can carry a few suitcases whether the roof is up or down.

Speaking of putting the roof down, the BMW M240i Convertible makes a great countryside cruiser. Its 340hp six-cylinder engine is smooth, sounds lovely and has enough poke to blast you from 0-62mph in five seconds flat.

The standard manual gearbox is lovely and precise, but if you spend a lot of time in town you’ll want to get the optional automatic instead. It doesn’t just make the BMW M240i Convertible easier to drive, it also makes it slightly more economical.

The standard suspension does a good job ironing out bumps around town and stopping the BMW M240i Convertible’s body leaning in tight corners, but the optional Adaptive M Sport Dampers make it better still. This system lets you choose between softer settings for long motorway journeys and firmer setups to make the car feel more agile on twisty roads – effectively letting you have your cake and eat it.

Even with its upgraded suspension turned up to 11 though, the BMW M240i Convertible doesn’t feel quite as sharp as the Porsche 718 Cayman. But, it’s still huge fun to drive and will be easier to live with every day.
