By now, I imagine all F1 fans have probably watched the first Grand Prix of the season. I finally had a chance to watch it last weekend and I must say, I was quite disappointed with the noise. The major changes to cars have been decreasing engine size, rpm limit and cylinder count, a return to turbocharging, limiting fuel use, body changes to promote safety and increase passing opportunities and increase available power boost from the electric motor, both in duration and magnitude. If you want to learn more about the changes, click here to go to the summary on the Formula 1 official website or watch the video below prepared by the Red Bull. The changes to the engine itself are the ones that most affect the noise. Firstly, a drop from a V8 to a V6 means fewer cylinder fires per engine revolution and, therefore, per unit of time (second, minute, etc.). This is coupled with a drop in maximum rpm from the typical 18,000 - 19,000 to 15,000. This means fewer fires per revol
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
