Ken Block ain't got a care about ruining his wheels

During a drifting session at Irwindale Speedway in California, Ken Block made a boo-boo that would send a number of drivers immediately back to the infield. But there's an answer to "What do you do when you bash the wall while drifting and your wheel explodes?" and there's completely different answer when the question begins with the phrase, "When you're Ken Block..."
Instead of us telling you how Block handled the calamity in his Ford Fiesta competition car, you can watch it happen in the video below. You can probably also guess what it is - but it's more fun to watch.

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.

2021 Ford F-150 Raptor vs. 2021 Ram 1500 TRX | How they compare on paper

Yep, the F-150 Raptor is back, though you'd be forgiven for not noticing that it ever left. Ford's off-road model is taking a few months off to accommodate the broader 2021 F-150 redesign from which it benefits. And the fine folks over at Ram took full advantage of that lull to launch the new 702-horsepower TRX, which in one big way (hint: it's the engine) stands at the top of the performance pickup heap. Ford says that's all going to change in 2022, but for now, the Raptor returns with a familiar 3.5-liter EcoBoost V6 (albeit with an unspecified power figure) along with several other revisions to Ford's tried-and-true formula. The 2020 Raptor was already a worthy adversary to the beefy Ram despite the latter's definitive power advantage, so how has that picture evolved for 2021? Let's take a look.    Powertrain This is a big question mark for the Ford right now, but it seems reasonable to expect a bit more than the outgoing model's 450 horsepower and 510 pound-feet of torque. The TRX's Hellcat-sourced powerplant needs no introduction. Its 702 horsepower will easily eclipse whatever Ford has planned for its 3.5-liter twin-turbo V6, even if the V6 has more grunt than it did before, but that's OK. It's not the base-model Raptor's job to dethrone the TRX in straight-line speed; that honor will go to the 2022 Raptor R. We also don't know what the Raptor's fuel economy will be like, but we suspect it will be better than the TRX's, if only slightly.  Both these trucks come with four-wheel-drive standard, and they both have a number of drive modes that alter the powertrain’s characteristics depending on the terrain. Baja mode transforms the trucks into the desert runners that they both are at heart, but theyÂ’re plenty capable of crawling around rocks, too. We wonÂ’t know for certain which is best at specific tasks until we can get them both on (or off) equal ground. Suspension / off-roading capability And the ground is where things narrow significantly, both on- and off-paper. The specs are freakishly similar when we compare ground clearance, approach/departure angles and water fording, but the Raptor's leapfrog here is clearly evident. Both trucks utilize a coil-sprung rear suspension now, with Ford having abandoned the Raptor's previous leaf-spring setup with the redesign.  The two use different shocks to handle 100-mph-plus desert running.
