Ken Block's 1965 Ford Mustang Hoonicorn RTR and CR Supercars Villain are retro done right

Gymkhana king Ken Block has had a pretty simple car history in his trademark videos, starting out with Subaru Impreza rally cars before moving into Ford Focus racers for the past four installments. His next video, though, Gymkhana Seven, kind of goes back in time.
Rather than the cutting-edge rally racers of past videos, Block will pilot a heavily modified 1965 Ford Mustang, called the Hoonicorn. How heavily modified is it? Well, Block's Hooligan Racing Division, ASD Motorsports and Vaughn Gittin Jr.'s RTR, spent two years working on it, ditching the standard engine and rear-wheel-drive layout and replacing it with a 410-cubic-inch Roush Yates V8. Yes, that's a NASCAR engine, and it produces 845 horsepower.
A NASCAR-powered Mustang would be news in itself, but it's the other powertrain changes made by Block and Co. that really makes headlines. Power is channeled through a one-off Sadev transmission and all-wheel-drive system, meaning that Block has basically married a NASCAR stock car with a WRC racer. ASD also developed the customized suspension, tubular chassis and roll cage. The wide Mustang body is the work of RTR and Block's own Hoonigan Racing Division, while the 18-inch fifteen52 wheels are shod in Pirelli Trofeo R tires that use a specialized compound exclusive to Block.

GM already raising prices on 2014 Silverado and Sierra pickups

General Motors must be pretty pleased with sales of its two newest pickups, the GMC Sierra and Chevrolet Silverado, as it's announced price hikes for both models, as part of a planned price tweak.
Prices will be bumped by as much as $1,500, although weirdly, they'll be offset by as much as $1,500 in cash-back offers through the end of October. Fox Business reports that GM spokesman Jim Cain said of the price hike, "With the sell down of the '13 models nearly complete, this price adjustment was planned and is a normal part of business."
The move, as Fox is quick to point out, is an interesting one, as sales of the twin pickups struggled last month relative to the Ford F-Series, while both of GM's crosstown competitors have been aggressively undercutting Silverado and Sierra prices. The F-150 starts at $24,070 and the Ram 1500 comes in at $23,600, not counting any cash on the hood. A base Silverado, meanwhile, retails at $25,575.

Aluminum lightweighting does, in fact, save fuel

When the best-selling US truck sheds the equivalent weight of three football fullbacks by shifting to aluminum, folks start paying attention. Oak Ridge National Laboratory took a closer look at whether the reduced fuel consumption from a lighter aluminum body makes up for the fact that producing aluminum is far more energy intensive than steel. And the results of the study are pretty encouraging. In a nutshell, the energy needed to produce a vehicle's raw materials accounts for about 10 percent of a typical vehicle's carbon footprint during its total lifecycle, and that number is up from six percent because of advancements in fuel economy (fuel use is down to about 68 percent of total emissions from about 75 percent). Still, even with that higher material-extraction share, the fuel-efficiency gains from aluminum compared to steel will offset the additional vehicle-extraction energy in just 12,000 miles of driving, according to the study. That means that, from an environmental standpoint, aluminum vehicles are playing with the house's money after just one year on the road. Aluminum-sheet construction got topical real quickly earlier this year when Ford said the 2015 F-150 pickup truck would go to a 93-percent aluminum body construction. In addition to aluminum being less corrosive than steel, that change caused the F-150 to shed 700 pounds from its curb weight. And it looks like the Explorer and Expedition SUVs may go on an aluminum diet next. Take a look at SAE International's synopsis of the Oak Ridge Lab's study below. Life Cycle Energy and Environmental Assessment of Aluminum-Intensive Vehicle Design Advanced lightweight materials are increasingly being incorporated into new vehicle designs by automakers to enhance performance and assist in complying with increasing requirements of corporate average fuel economy standards. To assess the primary energy and carbon dioxide equivalent (CO2e) implications of vehicle designs utilizing these materials, this study examines the potential life cycle impacts of two lightweight material alternative vehicle designs, i.e., steel and aluminum of a typical passenger vehicle operated today in North America. LCA for three common alternative lightweight vehicle designs are evaluated: current production ("Baseline"), an advanced high strength steel and aluminum design ("LWSV"), and an aluminum-intensive design (AIV).
