BMW 335i Convertible

The 3 Series Convertible is BMW's first attempt at building a folding hard top, but it already a class leader.

What's New
It wasn't so long ago that BMW was pooh-poohing the idea of using a folding metal roof for its open-top models. But here's the all-new 3 Series Convertible and yes, it has one of those trick retractable hardtops. BMW may be a strongly engineering-driven company but it didn't become the top-selling premium brand by ignoring what its customers want.

Some compromises had to be made in the switch from fabric to metal, but thankfully none of them to do with styling. It has a lower, flatter boot section than the coupe it is based on and a sharper angle between the rear deck and the base of the rear windscreen, giving it a more distinctive profile from the side.

The roof retracts completely in 22 seconds and for the first time in a 3 Series Convertible, it can be triggered from the remote key as well as from inside the car. Because it's split into three pieces instead of the more common two, each section is smaller and the lot can be stacked tighter together.

Luggage space isn't great, falling from 350 litres to just 210 litres when the top is down, but most will agree it's a fair trade-off for the security and refinement the solid roof brings to the table.

Powering the range-topping Convertible is the muscular twin-turbo 3.0-litre engine that made its debut in the Coupe. One indication that this car is more cruiser than bruiser though is that the base model is a 320i with a 170bhp four-cylinder powerplant, whereas the smallest-engined Coupe you can buy is the six-cylinder 325i.

How it Performs
It's really quite amazing how the 335i feels as keen and nimble as it does, given that it weighs a substantial 200kg more than the equivalent Coupe. While there's a touch more body roll and the steering isn't quite as communicative, you'd need to be pushing really hard to notice this at all.

The 306bhp engine isn't fazed by the extra weight. Floor the throttle and the car just picks up its heels and goes, with acceleration not tapering off until the speedometer needle is deep into the right hand side of the dial. Roof down, there's the added bonus of listening to the glorious exhaust note in full 3D surround.

Most of the time the Convertible drives just how you'd expect a 3 Series to - amazingly balanced through corners and rock-solid at high speeds - but with the added bonus of a genuinely plush ride thanks to the revised suspension.

The seats are firm and supportive, all the controls operate with well-oiled precision and the innately driver-focused feel that's a hallmark of all BMWs is immediately obvious.

How it Stacks Up
Incorporating a folding hardtop in a 3 Series was always going to be a challenge, but it's one that BMW has risen to admirably. The Convertible is great with its roof down, and in closed mode it's fantastically refined. Yet it has a distinct appearance and character that sets it clearly apart from the Coupe.
The car is due to hit Singapore showrooms by the middle of this year, which means a shorter than expected wait to get their hands on the clear class leader.
