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.

Ranger in the USA, Alfa in Italy, and Volvo goes RWD | Autoblog Podcast # 780

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Associate Editor Byron Hurd. They start off with this week's big news, including the official unveiling of the U.S.-market Ford Ranger and Ranger Raptor, some new RWD options from Volvo, and the potential production status of the Hyundai N Vision 74 concept. They also cover the discontinuation of the Mercedes-Benz CLS and the introduction of the latest RS model in Porsche's lineup, based on the 718 Spyder. From there, Byron talks about driving the new Alfa Romeo Tonale, and Greg digs into the new Lexus IS 500 F Sport Performance. After that, Byron talks about his Wankel-based discovery during his tour of Alfa Romeo's factory museum outside Milan.  Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

Ford finds flex-fuel engine design plays big role in emissions output

How bad is ethanol for your engine? There's been a lot of debate on this issue as the US considers upping the biofuel content in the national gasoline supply from 10 percent (E10) to 15 percent (E15). The ethanol industry and some scientists say higher ethanol blends show no "meaningful differences" in new engines while the oil industry says ethanol creates health risks. Researchers working at the Ford Research and Innovation Center decided to take a closer look at how a wide range of gas-ethanol blends - E0, E10, E20, E30, E40, E55 and E80 - affected the emissions coming out of a flex-fuel 2006 Mercury Grand Marquis. To see the full report, printed in the journal Environmental Science & Technology, requires payment, but there is an abstract and Green Car Congress has some more details. The gist is that, "with increasing ethanol content in the fuel, the tailpipe emissions of ethanol, acetaldehyde, formaldehyde, methane, and ammonia increased." At least NOx and NMHC emissions decreased. The researchers say that the effects are due to the fuel and "are expected for all FFVs," but that the way that a manufacturer calibrates the engine will affect NOx, THC, and NMOG emissions. It's this last bit that's important, since the researchers found, "Higher ethanol content in gasoline affects several fundamental fuel properties that can impact emissions. ... These changes can have positive or negative effects that can depend on engine design, hardware, and control strategy. In addition to direct emissions impacts, higher ethanol content fuel can also provide more efficient combustion and overall engine operation under part-load conditions and under knock-limited higher-load conditions." So, as we head towards more ethanol in our fuel supply (maybe), manufacturers are going to need to learn how to burn it most efficiently.
