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 r...
I'm finishing up a comparison post (link to introduction: Intro: Focus RS vs Golf R vs WRX STI vs Evo X ) and, throughout the post, I realized that I have to go off topic a lot to talk about how each type of differential changes the way the car drives. As a result, I thought I'd write a separate post to go into more detail before I post the comparison to keep it more focused on the cars and avoid veering off topic too much. By saying "Limited Slip Differentials" in the title, I am including torque vectoring diffs because, although current conventional terminology treats them differently, a torque vectoring differential is, in essence, a very sophisticated limited slip diff (LSD) that can be manipulated to actively help the car handle better. And while none of the cars in the comparison use open (without help from the brakes) or non-gear mechanical LSD’s, I’ll briefly discuss them so that the post is more inclusive. I’ll only focus on using power to help the...
