The <a href="http://www.autoblog.com/bmw/x5/">BMW</a> specialists at <a href="http://www.autoblog.com/tag/alpina/">Alpina</a> know how to exploit a niche when they see one. With the <a href="http://www.autoblog.com/bmw/m4/">BMW M4</a> still <a href="http://www.autoblog.com/2014/02/10/2015-bmw-m4-convertible-spy-shots-photos/">not technically official</a>, it saw the need for a higher performance four-seat convertible than the <a href="http://www.autoblog.com/bmw/4+series/">435i</a> 'vert. Enter the new B4 Bi-Turbo Cabrio that is debuting at the <a href="http://www.autoblog.com/geneva-motor-show/">Geneva Motor Show</a>.<br />
<br />
The European-exclusive model takes BMW's 3.0-liter, twin-turbocharged inline-6 and massages it up to 410 horsepower and 442 pound-feet of torque, which is less power but more twist than the M4 would give buyers. Alpina's tend to be built more as quick, luxurious grand tourers, and the B4 Bi-Turbo gets is no different with an adaptive sport suspension and an eight-speed automatic. Plus it wears the classic pinstripes and 21-spoke wheels that are the brand's design hallmarks.<br />
<br />
While the added weight for the convertible means that the Cabrio takes 4.5 seconds to reach 62 miles per hour, about a half-second slower than the coupe, at the moment it is the only way to get this kind of performance in a BMW convertible. Orders for the convertible open in March in Europe and prices in Germany start at 74,800 euros ($102,878 at today's conversion rates).<p><a href="http://www.autoblog.com/2014/03/04/2014-alpina-b4-bi-turbo-cabrio-geneva-2014/" rel="bookmark">Continue reading <em>The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed</em></a></p><p style="padding:5px;backgr ound:#ddd;border:1px solid #ccc;clear:both;"><a href="http://www.autoblog.com/2014/03/04/2014-alpina-b4-bi-turbo-cabrio-geneva-2014/">The 2014 Alpina B4 Bi-Turbo Cabrio powers up luxury and speed</a> originally appeared on <a href="http://www.autoblog.com">Autoblo g</a> on Tue, 04 Mar 2014 13:32:00 EST.
