BMW says the "new 4 Series Convertible represents something more than its BMW 3 Series cousins – 3+1, if you will." We're not sure what that means, but it's pretty clear what you get for your $49,675 starting price: a 4-Series Coupe that lets its hair down.
Perhaps more than any other convertible in the luxury compact segment, the last-generation BMW 3-Series Convertible wore its top up with grace and elegance, looking like a purpose-built coupe--then opening up to the sun with equal ease. The 4-Series Convertible does that, but better.
Just like the 4-Series Coupe it shares a name with, and the 3-Series sedan it plants its roots in, the 2014 BMW 4-Series gets a choice of 428i and 435i models. The engines offered match as well, with the 428i using a 240-horsepower, 2.0-liter turbo four-cylinder, and the 435i using the familiar 300-horsepower, 3.0-liter in-line six-cylinder.
The 428i is the $49,675 option (price includes destination), while the 435i starts from $55,825.
The 428i isn't blisteringly quick, but it's snappy, getting to 60 mph in 6.2 seconds and carrying on to an electronically limited top speed of 155 mph. The 435i is a touch quicker, hitting 60 mph in around 5.5 seconds, according to BMW.
Longer, wider, and therefore lower-looking, the new 4-Series Convertible is a larger car than its predecessor, positioned to be a luxury upgrade not only in name but in fact.
Rear-wheel drive is the standard fare for both trims, but the 428i will also offer xDrive all-wheel drive. Both models get a standard eight-speed automatic transmission with wheel-mounted paddle shifters. Normal and Sport modes help the transmission match its shift patterns to expected driver behavior. The BMW Driving Experience Control also offers Comfort, Sport, or Sport+ modes (on most models) to tweak powertrain and suspension settings for the desired traits.
An ECO PRO mode combines with Auto Stop Start to help boost gas mileage, while Brake Energy Regeneration stores power to help keep the electrical system running when stopped at lights.
The folding hard top for the 2014 BMW 4-Series Convertible has been significantly revised, says BMW, resulting in a 2-dB quieter interior and better weather insulation. The three-piece hardtop retracts in 20 seconds at speeds up to 11 mph.
A redesigned windblock is standard (and it now stows behind the rear seat), and three-temperature neck warmers are available, to improve comfort in low-temperature or high-speed top-down driving.
With the top up, the trunk offers 13.0 cubic feet os pace--about 0.7 cubic feet more than the 3-Series Convertible it replaces. With the top up, the rear seat can also be folded down, expanding available cargo space further. A load-thru opening is also standard.
Otherwise, what you'll see in the new 2014 BMW 4-Series Convertible is very much like what you'll find with the 2014 BMW 4-Series Coupe, or the new 3-Series sedan (and Sport Wagon) for that matter. Exterior and interior design echoes those vehicles, as does the interior layout and equipment set.
An M Sport version is also available, adding the M Aerodynamic package (front bumper, rear bumper, diffuser, and side skirts) plus a unique set of wheels and M-branded details inside and out.
