Famed BMW tuning house Alpina showed up at the 2011 Tokyo Motor Show with a world premiere, the limited edition B3 GT3 of which only 99 examples will be built, each carrying a price tag of €90.000 (approx. US$120,000) in Germany.
The B3 GT3 is based on the regular 3-Series Coupe and it uses a slightly modified version the 3.0-liter twin-turbocharged inline-six found in Alpina's B3 S Bi-Turbo sedan, coupe and touring models.
Thanks to a different exhaust system and a titanium rear silencer made by Akrapovic the three-liter unit gains 8 more ponies lifting output to 408-horses at 6,000rpm and 540Nm (398 lb-ft) of torque at 4500rpm.
