Evo grabs Ford's Fiesta R5 rally car by the scruff

Evo and host Henry Catchpole were thinking of excuses reasons to borrow the bonkers Ford Fiesta R5 rally car for a day or two, when it struck them: the car is street legal. With access to the R5, some of the world's most beautiful driving roads in the English Lake Country nearby, and a handy video crewing hanging around, the plan seemed to write itself.
Based on the resulting video, it was a good plan. Without spoiling the video for you - something we can't really do in text as the best part is listening to the rally car run - Catchpole finds the Fiesta to be sublimely quick and massively satisfying. Even taking the car for a spin on a pseudo rally stage, after leaving the English countryside, does nothing but add to his assessment of the beastly little Ford. Scroll on below to see for yourself, and enjoy the ride.

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).

Chris Harris pits Fiesta ST against Mercedes G63 AMG in 0-60 battle... sort of

Vehicle performance tests are serious business, with reputations made or broken by things like braking distance, top speed, and lateral g-forces. King of the metrics, though, is the 0-60 run, which for unknown reasons has become the benchmark for what truly makes a car a performance machine.
Now, Chris Harris from Drive has turned the whole idea behind the sprint to 60 on its ear. Taking a new Ford Fiesta ST, Harris asks a simple question: would the ST be quicker to 60 on its own, or on a trailer being towed by a Mercedes-Benz G63 AMG?
It's a fair question, really. The Fiesta Harris tested hit 60 in 7.2 seconds on a slightly uphill section of runway. It should be noted that Harris quotes his ST at 182 horsepower, which is about 15 ponies less than what we're getting in the US, so these numbers might not hold up all that well against an American model. The G63 AMG, meanwhile, is a 536-horsepower monster, powered by a twin-turbo V8 that, able to propel the big SUV to 60 mph in just 5.2 seconds without towing a Fiesta.
