Despite hearing and reading the rumours over and over again about the all-new, 5.5 litre, naturally aspirated high revving V8 Chevrolet was putting in the upcoming C8 Z06, I am still completely awe struck by what Chevrolet has done and sticking to a naturally aspirated V8 against all odds. Please take a moment to welcome the most powerful naturally aspirated production V8 the world has ever seen (at least mainstream production). The title previously belonged to the now dead SLS AMG, which had AMG's legendary 6.2 litre V8 making 622 hp and 468 lb-ft of torque. The New Z06 eclipses the horsepower figure with a whopping 670 hp at a scarcely believable 8,400 rpm (with an 8,600 rpm redline). Despite the high revving nature AND the smaller displacement (5.5 litre vs 6.2 litre for the Merc), torque hardly suffers with a healthy 460 lb-ft of torque, only 8 lower the the bigger displacement AMG engine. At a time when AMG, BMW, and even Ferrari have abandoned naturally aspirated V8s, and af...
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...
