Ford reveals concept trucks that ultimately became Atlas

The Ford Atlas Concept was one of the quiet success stories of the 2013 Detroit Auto Show, and now Ford has given us a quick glimpse as to how that creation came to be. Designers actually combined two early sketches to build the Atlas. One, called the Bullet Train, is a futuristic, aerodynamic creation, while the other, aptly named the Locomotive, features the squared off proportions we're familiar with.
Once designers settled on the truck's proportions, they began nailing down exactly which attributes they wanted the final design to have. The Concept's notched windshield originated as a forked glass roof that seamlessly transitioned into the windscreen.
Likewise, designers wanted to fit the truck's tailgate with a storage compartment for tools and a first aid kit, but settled on the dual-purpose step/cargo cradle. Interestingly enough, the concept's active aero shutter wheels actually originated in some of the earliest sketches. Check out the photos and slides here for a closer look.

2013 Shelby GT350

Shelby is a name as synonymous with the Ford Mustang as marshmallows are with campfires. But unlike the short-lived sugary confection that is prepared on a stick, the late Carroll Shelby's name on the placard means added performance and exclusivity. Launched in 1965, the automaker's celebrated early cars were in production for a limited run - today, a mint concours-quality 1965 Shelby GT350 can sell for upwards of $350,000.
To coincide with the 45th anniversary of the original Shelby GT350, Shelby American reintroduced the GT350 in 2011. Like the original, it was only offered in white with blue stripes. Customers were offered a choice between naturally aspirated (440 horsepower) and two levels of supercharging (525 horsepower with a warranty or 624 horsepower without). The manufacturer calls the GT350 a "post-title" package, a term that means it starts out life as a stock Mustang and is modified outside Ford's factory (this is in contrast to the Shelby GT500, which is a standard Ford production car).
As the GT350 enters its third year, Shelby has made several changes. Mechanically, Wilwood brakes replace Baer units and Recaro seats and a tinted glass roof are on the options list. Cosmetically, the vehicle is now offered in most of the Blue Oval's factory colors, new multispoke wheels are available in Satin Black or Bright Silver Metallic finish, and customers can choose between Satin Black, Silver or Gloss White stripes (or Azure Blue Metallic on Performance White or Ingot Silver). Aesthetically, the look of the car has also changed somewhat - keen eyes will note that it actually appears more 'stock' than it did last year.

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.
