The tricky business of octane, power, and MPG

Given tepid green-car sales numbers this year, consumers in the US aren't making the transition away from internal combustion engines too quickly. Regulations are still mandating cleaner emissions, though. In addition to downsizing and turbocharging, there's growing consideration about moving to higher-octane fuel to improve overall efficiency. In a new report, engineers at FCA, Ford and General Motors Powertrain are showing that it could work, too. The major advantage to higher-octane fuel is that it supports higher compression ratios. That in turn can lead to more power from burning the same amount of gas. "Higher ethanol content is one available option for increasing the octane ratings of gasoline and would provide additional engine efficiency benefits for part and full load operation," the researchers write in the study's abstract. The authors even think it could be possible to update some modern vehicles' engine calibration to be optimized for the better gas. While the benefits are there, we still have a long way to go before higher-octane fuel becomes a national standard. According to Green Car Congress, 87 percent of the gas sold in the US is regular grade 87-octane. Meanwhile, premium 91-93 octane makes up just 10 percent. The various grades of fuel illuminate even more annoyances with the current system. For example, Ford generally recommends 93-octane for EcoBoost engines, and the power outputs that the company publishes are based on using it. However according to Green Car Reports, such premium gas is very difficult to find in some regions of the US, especially along the West Coast. The powertrains still run on lesser grades but with lower power output. The researchers' discussion of possibly increasing ethanol in gas also comes during a heated debate on the substance. The current administration is pushing for less of the corn-based fuel in the coming years. Although, several presidential hopefuls might be favor of reversing that course.

2016 Ford Shelby GT350 Mustang rated at 526 hp, 429 lb-ft

When Ford debuted the Shelby GT350 Mustang at the LA Auto Show last year, we were told it'd have more than 500 horsepower and over 400 pound-feet of torque. And indeed it does; Ford confirmed today that its hot 'Stang will make 526 hp at 7,500 rpm and 429 lb-ft at 4,750 rpm. Compared to the GT350's main rival, the Chevy Camaro Z/28, that's an increase of 21 hp, but a loss of 52 lb-ft. That said, this Mustang packs some serious prowess, especially in its most hardcore GT350R trim. It sounds pretty wicked, too. It's worth noting that both the standard GT350 and GT350R use the same engine, with the same output ratings. It's also worth noting that this is a flat-plane-crank engine. It's the most powerful naturally aspirated engine Ford has ever made, with 102 hp per liter. Redline is 8,250 rpm. It's a lightweight engine, too – the 5.2-liter mill weighs less than Ford's own 5.0-liter Coyote V8. Perhaps most impressive is the price point for the 2016 Shelby GT350. The standard car comes in at $47,870, while the GT350R will command $61,370 – a big drop over the Camaro Z/28 and it's $73,300 sticker price (including destination but not gas guzzler charges). Ford confirmed the power output news at a media briefing today near its headquarters in Dearborn, MI. Stay tuned for more information as it becomes available. Related Video:

Watch this Ford F-150 SVT Raptor fly like an eagle [UPDATE]

The Ford F-150 SVT Raptor is a very capable truck right out of the box, but "capable" has never translated into "invincible." Just ask the owner of the machine in this video. In it, the driver gets frisky with an aggressive jump with plenty of speed on his hands. The result is enough air to make Vaughn Gittin Jr. blush. As always, it's not the launch that's painful, but the re-entry. Gravity eventually asserts its dominance over the $43,630 pickup in a big way, and when it comes crashing down, it does so with a vengeance.
The impact was hard enough to set off both the alarm and multiple airbags inside the cabin. It's unclear if anyone was injured in the stunt, but we certainly wouldn't be surprised to hear that was the case. You can check out the stunt in the video below, and remember, when in doubt, back out of the throttle. Be warned, there may be some explicit/NSFW language in the clip.
UPDATE: Second video added with an even better look at the jump added below.
