2006 Hamann BMW M5 Edition Race

HAMANN offers its clients three different engine tuning options. The high revving 5-litre V10 with 507 bhp and 520 Nm is limited to 250km/h as standard. By removing the engine limiter, the racy Bavarian can reach top speeds of between 300km/h and 320km/h, depending on the wheel and tyre combination. The second option is made up of a combination of removing the engine limiter and optimising the engine characteristics by reprogramming the standard engine computer. HAMANN manages to tease an additional 30bhp/26kW and 15 Nm out of the V10 engine. The “HM/M +60″ sport kit provides even better performance. The kit is made up of high-performance headers, metallic sports catalytic converters, a sports rear silencer, a sports air filter, an engine map optimisation and the removal of engine restrictions. As the name of the sports kit already suggests, the engine then provides around an additional 60bhp/44kW and can provide an extra 54 Nm of torque, meaning that a notably faster top speed of up to 320km/h can be reached.

Dirito Brothers’ Dealerships Step up to Support Nissan 350Z T2 Race Program
If you’ve been following this column, you’ll remember a very flattering article last month about the Mitsubishi EVO VIII MR, with an evaluation of its potential for racing action with the SCCA. Well, we’ve taken a step further into this racing discussion, and – this time – we got hooked. Last February, we began a discussion with Don Dirito of Dirito Brothers Nissan, VW, and Saab in Walnut Creek and Concord about the possibility of racing a Track model 350Z with support from their dealership. While we have a very high degree of respect for the EVO, when it comes to racing, there is just something about a traditional, normally aspirated, rear wheel drive two-seater sports car. And this appeal grew as we did more homework and discovered that the 350Z had shown well in the SCCA national racing program. Don Dirito was not familiar with SCCA racing.

2008 Chevrolet Corvette Z06 Pops 505hp

The aerodynamics of the Z06’s exterior were shaped by the experiences of the Corvette racing program, where high-speed stability and cornering capability are paramount. And while the race cars use large rear wings, the Z06’s elevated spoiler provides sufficient downforce to balance the road-worthy front splitter without adversely affecting aerodynamic drag. The Z06’s Cd is 0.34.
For all its race-inspired functionality, the Z06 is designed to be a daily-driveable high-performance vehicle. To that end, comfort and convenience are held to a very high standard.
