A few days ago, I made a post about about Motor Trend's test of the Audi S8. It does a 0-60 mph sprint in 3.5 seconds and goes through the 1/4 mile in 11.8 @ 118.3 mph.. very impressive numbers. Even more so when you look at a couple other cars: 2012 Porsche Panamera Turbo S 0-60 mph: 3.5 s 1/4 mile: 11.8 s @ 118.0 mph Power: 550 hp Torque: 553 lb-ft Weight: 4,388 lb 2012 Audi R8 GT 0-60 mph: 3.5 s 1/4 mile: 11.5 s @ 125.1 mph Power: 560 hp Torque: 398 lb-ft Weight: 3,484 lb Now let's compare those to the Audi S8 0-60 mph: 3.5 s 1/4 mile: 11.8 @ 118.3 mph Power 520 hp Torque: 481 lb-ft Weight: 4,619 lb The Panamera and R8 have weight to power ratios of 7.98 lb/hp and 6.22 lb/hp. The S8? Well, that one has a weight to power ratio of 8.88 lb/hp... The identical 0-60 time of the R8 GT and S8 can somewhat be explained by their engines' way of induction. Since the R8 is NA, the torque curve probably isn't as meaty so even though it weighs a lot less an
Last year, I picked up a 2009 Lancer Ralliart to do a long term test with it as a dual duty track/daily. One of the first things I knew I was going to do was put a decent set of tires on it. The car came without OEM wheels which was actually good because I didn't have to hesitate about getting a good set of aftermarket wheels to support going wider. Thankfully, my friends at YST Auto Halifax set me up with a great set of Superspeed RF03RR wheels. The Wheels I had never even heard of Superspeed but I trusted the good folk at YST Auto who mentioned some customer cars running on track with them. These wheels are rotary forged which is basically a prerequisite to be taken seriously in this market populated by companies like TSW and Fast Wheels. The wheels looked like a high quality, well finished wheel and each had a "QC" check sticker on. Just for appearances? Maybe, but I found no defects. The wheels seemed easy to balance (didn't need many weights) and at 18.1 lb. f
