XCAR stages epic drag race between Ford GT40, GT70 and GT

XCAR has put together what it believes is a first - a drag race between Ford's legendary, Le Mans-winning GT40, the more recent GT supercar it inspired and the little-known GT70 rally car. The three mid-engined monsters were all built for very different purposes, and not surprisingly, they come to battle with very different powertrains.
The GT40 is powered by a thumping, naturally aspirated V8. This example, which looks like a Mark IV model, is likely powered by a 7.0-liter engine, although it's not entirely clear how much power it's putting down. The GT70, meanwhile, was Ford's response to the Lancia Stratos. Considering that the Lancia is one of the greatest rally cars in history and many of you are probably just hearing of the GT70 for the first time, you can imagine how much success Ford had with it. Only six were produced before a change in regulations doomed this mid-engined rally car.
The Ford GT, meanwhile, doesn't really need an introduction. 550 horsepower is on offer from a 5.4-liter, supercharged V8, which keeps the GT competitive even against more modern supercars. 60 miles per hour arrives in well under four seconds while the top speed sits at 212 mph. Not bad for a car that went out of production in 2006.

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.

Nuclear-powered concept cars from the Atomic Age

In the 1950s and early 60s, the dawn of nuclear power was supposed to lead to a limitless consumer culture, a world of flying cars and autonomous kitchens all powered by clean energy. In Europe, it offered the then-limping continent a cheap, inexhaustible supply of power after years of rationing and infrastructure damage brought on by two World Wars.
The development of nuclear-powered submarines and ships during the 1940s and 50s led car designers to begin conceptualizing atomic vehicles. Fueled by a consistent reaction, these cars would theoretically produce no harmful byproducts and rarely need to refuel. Combining these vehicles with the new interstate system presented amazing potential for American mobility.
But the fantasy soon faded. There were just too many problems with the realities of nuclear power. For starters, the powerplant would be too small to attain a reaction unless the car contained weapons-grade atomic materials. Doing so would mean every fender-bender could result in a minor nuclear holocaust. Additionally, many of the designers assumed a lightweight shielding material or even forcefields would eventually be invented (they still haven't) to protect passengers from harmful radiation. Analyses of the atomic car concept at the time determined that a 50-ton lead barrier would be necessary to prevent exposure.
