Evo has been doing a pretty interesting Car vs. Bike track battle series. The latest installment is particularly interesting because they put a KTM motocross bike up against some rally cars. Up first is a hardcore Safari rally gravel spec 240Z followed by a tarmac spec Mitsubishi Evolution. I won’t spoil the results, but it’s interesting to see how the driving styles are changed for running long travel suspension and gravel tires on tarmac. There’s also a jump on the course where the effects of vehicle weight on speed are hyper amplified.

Ken Block and Need for Speed teamed up to film the sixth installment of the world famous Gymkhana video series. They set out to create the ultimate gymkhana course which resulted in some pretty solid stunts. Check it out:

Big rig stunt and race driver Mike Ryan teamed up with Gale Banks of Banks Power to redesign the compound turbo setup on his Freightliner race truck for this year’s Pikes Peak International Hill Climb. Mike had previously been running turbos designed for tractor pulls. The problem is the setup only made power at high engine rpm’s and it wasn’t getting enough air into the Detroit Diesel inline-6 at low rpm’s. This made the truck sluggish accelerating out of the turns on the hill climb. Gale Banks thought it would be more useful for Mike to have a super-turbo which is also known as twincharging. This is when an engine has both a belt-driven supercharger for low rpm boost and an exhaust-driven turbocharger for efficient high rpm boost. Banks Power also adapted a fuel injection system for use with a water and methanol mixture. Meth injection is used before and after the supercharger as well as being directly injected into the cylinders to lower the temperature of the compressed air for more efficient combustion. They also designed a water fogger system to cool the intercooler and the front brakes of the truck. The end result is 2,500 horsepower and 5,000 foot-pounds of usable low-rpm torque. Gale Banks explains all of the upgrades in this interview:
Here’s some race footage of the Freightliner on course at Pikes Peak. Mike and Gale talk about the effectiveness of the super-turbo system at the end. The course was pretty wet this year which resulted in slower times, but these two guys want to come back for 2014 and be the first semi in the 11-minute range.

Ride along with Finnish driver Mikko Hirvonen as he pilots his Citroen WRC car through Stage 10 of the 2013 Neste Oil Rally Finland. He is absolutely flying through the woods. This footage is a pretty nice insight into a world class driver piloting a world class rally car.
The Fast Lane checks out the Toyota Motorsports Group EV P002 and the Mitsubishi i-Miev Evolution to see what incremental improvements were made to take on the mountain this year. Both cars are now capable of more power output and downforce compared to how they ran during 2012. The video include interviews with the engineers and footage from their practice sessions.
