BMW 4-Series Convertible

Last week we had the chance to get a glimpse at the new BMW 4-Series Convertible in the leaked accessories brochure, but earlier this week the German carmaker released full details on the upcoming car which is scheduled to debut next month at the 2013 L.A. Auto Show. The new convertible is the second model in the 4-Series lineup and will replace the current BMW 3-Series Convertible, keeping the retractable hard-top as its main “attraction”. The previous generation was the first 3-Series to feature the retractable hard-top and BMW thought it would be a good idea to keep it for the 4-Series too, even though most competitors have chosen soft-tops. The 4-Series Convertible features a three-piece hard-top with special soundproofing materials designed to improve interior comfort when the top is up.

According to BMW, the hard-top takes only 20 seconds to “hide” in the trunk, and this operation can be done at speed of up to 11 mph (18 km/h). When the top is down, luggage space is reduced from 370 liters to 220 liters, which BMW thinks its enough, even though it’s less than what the 3-Series is currently offering (350/210 liters).

Under the bonnet, the new BMW 4-Series Convertible will be available with only three engine choices. The European market will get only one diesel option, the 420d Convertible powered by the 2.0-liter turbocharged four-cylinder unit that delivers 184-hp at 4,000 rpm and 380 Nm available between 1,750 and 2,750 rpm. This translates into a 0 to 62 mph (100 km/h) sprint made in 8.2 seconds and a top speed of 146 mph (235 km/h). As for petrol choices, BMW will offer two options. The first one is the BMW 428i Convertible, powered by a four-cylinder turbocharged 2.0-liter unit that delivers 245-hp at 5,000 rpm and 350 Nm between 1,250 and 4,800 rpm and which is capable of accelerating from 0 to 62 mph (100 km/h) in 6.4 seconds and reach an electronically limited top speed of 155 mph (250 km/h). The second petrol powered model will be the 435i Convertible flagship which comes with an in-line six-cylinder 3.0-liter unit that produces 306-hp at 5,800 rpm and 400 Nm between 1,200 and 5,000 rpm. This is one of BMW’s “classic” engines and is designed to try and please sports convertibles fans until a future M4 Convertible will be launched. The 435i needs just 5.6 seconds to go from 0 to 62 mph and top speed is electronically limited at 155 mph (250 km/h).

All three engines are available with a six-speed manual or an eight-speed automatic transmission and come as standard with the Start-Stop system. Customers will be able to choose between three trim levels, Sport, Luxury and Modern, while an M Sport package is also available, looking to please customers that are more performance oriented. Following its debut in Los Angeles, the new BMW 4-Series Convertible will hit showrooms next year, with sales scheduled to debut in March 2014.
