The 2009 BMW Alpina B7 Bi-Turbo will join the B6 GT3 race car on the stand in Geneva, and thanks to AutoZeitung, we’ve got a singular photo and some preliminary specs on the uber-sedan from Alpina.![](https://lh3.googleusercontent.com/blogger_img_proxy/AEn0k_sD0VCfJ0KwUBacMf5QTDCE4NxY5S17_p4Mc8HlK11UFPIzhFvyBzyl8nF0v4nuDYx4Ht3bsAj-qh1-l8-pCoj7AaB_YVMk4WgTGuZ8HVsUNwAGjagpiTr3-kTBvDwKQu6z_24hip3J0WsDbA5tmU9Eq7_4i2kVNgGg2Ows5qsAXgvy0BnWFW-LvHEhW5g__IWffBks6GdsrA=s0-d)
The B7 Bi-Turbo is essentially the M7 BMW forgot to build, packing a twin-turbocharged, 4.4-liter V8 putting out 507 hp and 516 lb-ft of torque. Alpina claims the B7 can run to 60 in 4.7 seconds and on to an electronically-limited 173 mph. We’ll have more details from the Geneva Motor Show next week, but expect a host of upgrades to join the engine mods, including uprated brakes, suspension components and a reworked interior to compliment the B7’s new body kit
