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.

FCA and Cummins named in diesel emissions class-action lawsuit

Chrysler is now the first United States-based carmaker to be sued for allegedly skewing emissions results. In a move that sounds eerily similar to the troubles of European manufacturers, Chrysler is claimed to have hid diesel engine characteristics causing emissions as much as 14 times higher than permitted by regulations. According to Bloomberg, the lawsuit alleges that Chrysler, together with its diesel engine partner Cummins, has concealed the nitrogen oxide output of certain Ram vehicles produced between 2007 and 2012. The NOx pollutants were meant to be broken down in a process called regeneration in the truck's NAC system, or NOx Absorption Catalyst, which predated the 2013-introduced SCR, or Selective Catalytic Reduction system. By design, the NAC captures and stores NOx emissions, converting them to nitrogen and oxygen through a catalytic process. The lawsuit claims the Cummins engine's system has a limited capacity to store the emissions, and as a result the pollutants escape, increasing emissions, worsening fuel consumption and wearing down the catalytic converter. The later, cleaner SCR system uses a urea-water injection, and it gradually replaced the NAC on Cummins 6.7-liter engines, as it was first implemented in 2011 and made standard in 2013. As Bloomberg notes, the model years of Ram trucks involved in the lawsuit predate the earliest Volkswagen "Dieselgate" models by two years. The lawsuit, filed on behalf of 500,000 truck owners, accuses Chrysler and Cummins of fraud, false advertising and racketeering. As an underlying motive, the filing mentions a 2001 change in EPA emissions standards. Announced to become effective in 2010, the EPA requirements drove Chrysler and Cummins to try and reach those already by 2007. However, the NAC system is said to have fallen short of these goals, and the filing claims that Chrysler and Cummins chose to "rig" the engines instead. The affected vehicles predate the 2014 merger of Chrysler and Fiat. FCA US has released a statement regarding the lawsuit, saying it will contest the lawsuit "vigorously".

2014 Ram ProMaster 2500

Front-wheel drive is what sets the all-new Ram ProMaster full-size commercial van apart from its competition. In a segment still choked with thirsty, rear-wheel-drive, ladder frame, pickup truck-based cargo vans, the American automaker is introducing something entirely new - well, new to our domestic market, as Europeans will recognize Ram's fresh entrant as a made-for-USA Fiat Ducato.
While the big ProMaster doesn't have a traditional body-on-frame chassis, it isn't a pure unibody either. Consider it a hybrid of both, with a unibody cab up front and a reinforced high-strength steel subframe in the rear. The platform employs double A-arms and MacPherson struts on the front axle, while the rear uses a simple tubular beam axle. Tires are 225/75R16 at all four corners. The steering is hydraulic rack-and-pinion (allowing an impressive 36-foot turning radius) and there are disc brakes with two-piston calipers all around. It is a solid, if unsophisticated, setup.
This game-changing van, which has already arrived in showrooms with a starting price of $28,630, is propelled by either a gasoline-powered 3.6-liter Pentastar six-cylinder (280 horsepower and 258 pound-feet of torque) or a new turbocharged 3.0-liter four-cylinder diesel (174 horsepower and 295 pound-feet of torque). Ram will offer a traditional six-speed automatic or a new six-speed automated single-clutch manual transmission that drops the hydraulic linkage to improve fuel economy - details are still emerging on this unique gearbox.
