Top torque-to-weight ratios under $100k, $50k and $25k

Horsepower may steal a lot of headlines, but the always-more-complex torque figure is often a critical one for both the workingman and the motoring playboy. The measure of rotational force represents the twist that can liquefy one's tires or haul one's horse trailer. Good stuff.
It follows then, that as with the horsepower-to-weight list that we assembled for you a few months ago, a list of cars that offer the most pound-feet with the fewest pounds to carry, is an interesting one to break down. Sure, there's a big difference in how the torque is applied from a turbocharged six-cylinder in a Swedish luxury sedan and a massive heavy-duty truck's turbo-diesel. But being the car/stat geeks that we are, we think it's kinda neat that those two vehicles rank near each other where torque and weight intersect.
As with the horsepower list, we've given you figures as pounds per every one pound-foot. Again broken down into broad price categories, we've got a mixed bag of 2014 and 2015 models here, too. Every effort has been made to select the most up-to-date prices and specs, and we've also to omitted some '14 cars that won't be re-upped after the ongoing yearly changeover.

Motor Trend pits Aston V12 Vantage S against Jaguar XKR-S GT in battle of the Brits

With the recent increase in higher-performance versions of already high-performance vehicles, like Mercedes-Benz and its AMG Black Series, the public is now gaining even greater access to speed and maneuverability. Two of the most recent sports cars to get their wicks turned up include the Jaguar XKR-S GT and the Aston Martin V12 Vantage S.
Both of these cars are the pinnacles of their lines, with the Jag lording over the XKR-S, XKR and XK while the Aston rules over the standard V8 Vantage S and V8 Vantage. Motor Trend has opted to pit the two rivals together for some thorough testing, and it just happened to bring along a few video cameras to capture all the action.
There's nearly 19 minutes of super hot sports car action below, so scroll down and enjoy.

Jaguar XF gets performance-look R-Sport trim

If you're looking for all the style of a sports sedan but without the added expense of springing for a full-on performance model (and keeping it fed with fuel and fresh tires), most European automakers will gladly hook you up with an all-show, no-go package. BMW has its M-Sport aero kits, Audi its S-Line, and Mercedes its AMG Sport packs. And now Jaguar is getting in on the action with the launch of the new R-Sport line.
Set to be introduced on the XF at the Geneva Motor Show, the R-Sport trim at least some of the flash of the XFR or XFR-S but with a more economical engine and a relatively accessible price of entry. (This is, after all, still a Jag.) The XF R-Sport is distinguished by a sportier front bumper, side sills, rear spoiler, 17-inch wheels and unique badging to set it apart from any "ordinary" Jaguar XF. The interior is upgraded as well, and there's an optional black styling pack to take things even further.
Jaguar is offering the XF R-Sport in either sedan or wagon form with the 2.2-liter turbodiesel producing 161 horsepower and 295 pound-feet of torque, fitted with a spot-start system to make it a far more frugal option than the 5.0-liter supercharged V8 in the real deal. Although this version won't be coming to US as you see it here, Jaguar tells Autoblog it's always possible it'll produce a similar aesthetic treatment for the North American market - just don't count on such models arriving under diesel motivation. We'll take a closer look at them in Geneva next week, but for now, you can check out the gallery and press release below for an idea of what to expect.
