From a post on Eric Rescorla’s Educated Guesswork I found out The Truth About Cars blog, an auto blog that is written by completely insane people who are nuts for cars. Eric points specifically to this review of the Audi RS4 (a super-hot sedan), and I’m going to quote the same parts he did because it’s JUST AWESOME.
Audi used every trick in the playbook to get the RS4 — with 58% of its weight over the front wheels — to handle near-on perfectly. Credit the DRC (Dynamic Ride Control) which hydraulically links the diagonal suspension bits to each other. As the front wheels read the road, the rear shocks preemptively (and correctly) react. This setup works so well the WRC just banned it. The engineers also made sure every body panel in front of the doors is composed of kilogram saving aluminum. And the 19′ Pirellis are fantastic. While the initial turn in isn’t as effortless and eager as say an EVO, this two-ton all-wheel driver can safely carry more speed through a corner than you can handle. After the apex, the RS4 can blast sideways with
such force that you will swear you are piloting violence.
And that’s before you push the innocuous little button marked ‘S.’ Normally, the RS4 is faster than whatever car you are driving next to, sounds bonkers and has a devastatingly punishing ride. Push the button though, and three things happen. First, the throttle control is
remapped so that the rev-happy mill will crank faster with less input. Second, valves open in the mufflers changing the sound from Howard Dean’s scream to Gunnery Sgt. Hartman showing Joker his war face. Lastly, the shocks get firmer and the ride goes from mercilessly
painful to f-you. I absolutely love it. Forget violence, you are now driving war.
Wow. Just. Wow.
