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.

2015 Dodge Challenger SRT 392

I've just started reading the third installment in a planned five-book biography of Lyndon Baines Johnson, Master of the Senate, written by the incomparable Robert Caro. Conveniently, a recent trip to drive the BMW X6 M and 228i Convertible was to be staged in Austin, TX, within easy driving distance of LBJ's birthplace, Johnson City. And yes, the city is named for his family. Having completed my duties with the Bimmers, I borrowed the spangled 2015 Dodge Challenger SRT 392 you see above, to squire me around the Texas capitol for a weekend, and as a lift out to the Hill Country homestead of our 36th President. Johnson City isn't exactly a road trip mecca, but there's a pretty good brewery, a museum, the reconstructed LBJ house to take snapshots of, and it's a nice drive to get out there if you've got a 485-horsepower muscle car at your disposal. Driving Notes With the heroic Hellcat, this 392 and the R/T Scat Pack (that Brandon Turkus reviewed recently), there are more SRT-treated Challengers to choose from than ever before. There are 707 obvious reasons that the Hellkitty is the top dog (as it were), but there are important difference between this 392 and the Scat Pack, too. Both cars make use of the 6.4-liter Hemi V8 putting out 485 horsepower and 475 pound-feet of torque, but the 392 also gets an adaptive suspension, six-piston Brembo brake calipers (instead of four-piston), wider tires, leather and Alcantara seats, a heated steering wheel, a louder stereo and HID headlights. When LBJ was campaigning for his seat in the House of Representatives, he would've loved to have something as potent as this monster of a V8 under the hood of his canvassing car. The 6.4L snorts with authority before it sends the big coupe forward to just about any speed I'd ask of it, and with a quickness. Johnson was known for haranguing drivers to step on it, when all that stood between himself and a few more votes was the ability to fit one more stump speech into the day. The 392 feels as though it could cover a quarter of the state of Texas in a morning if you throttle down deep enough (faster even than the Johnson City Windmill, I'd guess). Though there's a six-speed manual available, I'm actually quite fond of the eight-speed automatic in the 392. The two-pedal setup better suits the fast-cruiser attitude of the car, and it never served up any poorly conceived shift logic when I left it in D. Of course, the roads are better now than they were in the 1930s and 40s, too.

Speedkore AWD twin-turbo Carbon Charger, best birthday gift ever

The backstory the Speedkore Performance AWD twin-turbo Carbon Charger teased a couple of weeks ago might be cooler than the car itself. Alan Palermo commissioned the carbon-fiber-bodied Dodge Demon Speedkore brought to SEMA last year, the one that supplanted the 6.2-liter Hellcat V8's supercharger with twin 6875 Precision Billet T4 turbos. That blasted the Demon's usual 840 horsepower up to 1,400 hp at the flywheel, 1,203 hp at the rear tires, good for an 8.77-second quarter-mile time at 162 miles per hour. Palermo's older brother remarked, "He liked the car but was more of a four-door guy," so Alan commissioned the AWD Carbon Charger as a 65th birthday gift for his sibling. Speedkore worked with Magnaflow on the sedan, starting with a 2019 Charger Pursuit as a base. The Wisconsin tuner secured a 2020 widebody Charger from Dodge, then 3D-scanned the bodywork to create the molds reproducing most of the sheetmetal in pre-preg carbon fiber. The hood, bumpers, fenders, rockers, rear spoiler, and rear diffuser are all fashioned from the lightweight stuff.  Beyond those Precision turbos laid in by Gearhead Fabrications, Speedkore installed a custom upper plenum, Boost Leash C02 progressive boost controller, custom Thitek heads, a Fore Innovations triple-pump fuel system feeding Injector Dynamics 1,700-cc injectors, and custom HP Tuners engine software calibration. Test results showed 1,525 hp at the crank when running 26 pounds of boost.  Hellraiser Performance engineered a new transmission working an FTI torque converter at one end and a carbon fiber driveshaft at the other. Instead of fortifying an off-the-shelf AWD system, Traction Products supplied a custom transfer case machined from billet shunting power to a set of Bogart Competition Series wheels wearing Mickey Thompson ET street rubber.  Speedkore fitted last year's Demon with a front-exit twin exhaust, with a single opening on each front fender, and left the rear bumper cutouts for the traditional exhaust empty. With the Carbon Charger sedan more of a family guy, Magnaflow sorted out a quad-pipe front-exit exhaust with two openings on each front fender, and ran a three-inch stainless steel Competition Series exhaust to the rear. The driver can switch between the two, the latter version providing a "moderate interior sound."  The folks at Speedkore say they'll keep tweaking the Carbon Charger after the show to get it right for the senior Palermo. We say, "Happy birthday, sir. Enjoy."
