Studying engines, calculating hp, torque, efficiency, and exhaust flow for grades? Sign me up! It wasn't just the content, though, as magnificent as it was. The class itself was taught by the coolest prof there is. You may think you've had a cool prof, teacher, coach, or instructor, but I've got the standard by which all educators must be measured. For one, he or she has to teach something that is cool.. does it get cooler than Internal Combustion Engines? (No, in case you're wondering). This one is also a true gear head, so much so that he sticks around after class and argues about cars, performance, lap times, and racing. And occasionally does so in the middle of class.. For one class project, I proposed comparing the engines and specifications of the C6 Corvette ZR1 and the Ferrari 5
A few weeks ago, I made a post explaining mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky
