Today's horses must be Clydesdale-class, at least when compared to the horses we were saddling up back in the 1960s and early '70s. How else can you explain the real-world performance figures of yesteryear, when muscle cars were routinely pushing out well over 400 horsepower and quarter-mile timeslips in the 14s, with the 12-second runs we see today from a similar number of (rated) ponies? Well, actually, there are a number of reasons... and none of them has anything to do with a four-legged hor
Hemi. The mere mention of the word is enough to strike fear into the hearts of lesser powerplants... or at least images of a pair of scrubby-looking bottom-feeders that really love themselves some Ram Trucks. In any case, we're keenly interested in the latest Hemi engine from the Dodge Boys, in this case displacing a heady 392 (or so) cubic inches and placed gently inside the engine bay of the 2011 Challenger SRT8.
In typical Honda fashion, its premium Acura division will take a different path and has decided not to get sucked into a power race with its rivals. We already knew Acura had shelved plans for a larger V8 engine and a rear wheel drive platform. Product planning manager John Watts told Automotive News that the brand will instead focus on doing what needs to happen to meet the 2016 fuel economy standards which will be "tough."
Lexus is billing the IS-F as "Everything you thought we weren't," and the potential is certainly there. The engine bay is filled with 5 liters of 4-valve V8 putting out 416 horsepower and 371 pound-feet of torque. The Minilite-esque wheels hide a Brembo braking system with six piston front calipers and cross-drilled rotors 14.2 inches in diameter. The sill extensions wrap up the front fenders to form a styling detail reminiscent of extractor vents, and the rest of the body has been tweaked in th
At one time Japanese regulations prohibited engines in that country producing more than 274hp, and oddly enough a wide array of different engines were all rated at that same level. Given the actual performance of the cars, it was clear that many manufacturers were sandbagging. Audi appears set to do the same with its uber-powerful RS6. The twin-turbo V10 is expected to carry an official rating of 571 hp, but the actual output could be as high as 610hp. Does anyone actually need this much power i
"Thanks God for traction control," was the first thought that ran through our minds when we came across the reported power figures of the new Audi RS6. Floating around the tubes of the Internets are the chassis codes for the new RS6, which look something like this: Audi AG 47 7967 21 AAJ N31 N30 579 426 5002. What does all that mean? Well, the 579 figure is the metric horsepower rating, which is equivalent to about 571 HP, while 426 refers to the kilowatts, and 5002 is a reference to the cubic c
var digg_url = 'http://digg.com/hardware/Horsepower_101_Top_Gear_provides_false_info_on_GT500_horsepower_rating'; Someone help us understand what's going on here. In the latest episode of Top Gear, Richard Hammon revisits the Ford Shelby GT500 that the British motoring show tested late last year. For comparison's sake, Hammond brings along his own classic Shelby GT390. We're used to Top Gear bashing our U.S. ware at every opportunity, and the GT500 again takes a licking for having a suspensio
Last month, Automobile Mag generated some chassis dyno numbers with a turbocharged BMW 335i coupe that were a bit healthier than one would suspect, given the factory's rating of 300 HP at the crankshaft. In a follow-up, they're now stating that the 275 rear-wheel horsepower number that was reported was actually the lowest of four pulls; one even generated 283 ponies. And all of this was with 92 F ambient temps - the sort of air that usually kills the output of boosted engines.
