The new BMW Alpina B4 Biturbo Convertible
Wednesday, 5th March 2014 - BMWThe Alpina philosophy rests on a number of central pillars including effortless performance, abundance of torque, smooth automatic transmissions, an emotional soundtrack and precisely tuned suspensions. This in summary sophisticated driving experience with a sporty touch is perfectly suited for elegant convertibles where an open roof amplifies all sensations. Hence it is not without reason, that BMW Alpina Convertibles based on the BMW 3 Series have a small and particularly loyal group of enthusiastic owners who share a passion. The new B4 Bi-Turbo Convertible carries on this legacy with its impressive performance, driving dynamics and elegant silhouette.
The design of the B4 Bi-Turbo Convertible is characterized by short overhangs, precise, long-drawn-shoulder lines, a wide rear and the characteristic metal folding roof. The sporty and purposeful design of the front spoiler is dictated by functional air intakes and operates in conjunction with the modest rear spoiler to improve stability at high speeds. When the roof is open the B4 Bi-Turbo Convertible stands out with its sleek, clean look. The Alpina Classic 20” light alloy wheels fit seamlessly into the overall shape of the Convertible and lend it a particularly elegant presence.
It only takes 20 seconds and the press of a button to close the roof, which is possible up to a speed of 18 km/h, turning the Convertible into a winter- and weather-proof two-door. The shape of the roof line when closed differs from the B4 Bi-Turbo Coupé significantly due to the steeper rake of the rear windscreen, the flat boot lid and subtle rear spoiler – this gives the Convertible a very distinctive and stand-alone appearance.
