#AlpinaB5Bi-turbo

If the BMW M5’s 560 horsepower isn’t good enough for you, perhaps the Alpina B5 Bi-Turbo will satisfy your hunger for performance.

Alpina has just released a single teaser sketch of its new B5 Bi-Turbo model based on the brand new BMW 5 Series. Much like the 5 Series takes its style from the larger 7, the Alpina does the same, imitating the aerodynamic upgrades on the Alpina B7 models shown at the Chicago Auto Show and New York Auto Show earlier this year.

With the 5 Series being offered with the same 4.4-liter tinw-turbo V8 as the 7, we also expect a similar engine output of 500-hp and 516 ft-lbs of torque, and delivering a 0-60 mph time in the low 4 second range. (M5 anyone?) Other upgrades are sure to include larger wheels, lower profile tires, a modified suspension and custom interior.

The new Alpina B5 Bi-Turbo will launch at the Goodwood Festival of Speed, which starts on July 1st.
