2015 Ford Mustang EcoBoost flogged and analyzed by Ignition

Aside from the way it looks and perhaps its independent rear suspension, the biggest bit of news on the 2015 Mustang may be the inclusion of its 2.3-liter, turbocharged four-cylinder engine. That blown mill marks the first time since the Mustang SVO of the '80s that a turbo has been fitted under the engine of Ford's pony car.
The Mustang EcoBoost is the subject of the latest episode of Ignition from Motor Trend, giving us a great look at the technical, nitty-gritty side of the turbocharged coupe. Covering it from bow to stern, host Carlos Lago walks us through the boosted Ford before taking to the track for some driving impressions, with particular praise given to the low-end grunt of the 2.3-liter mill.
Check out the full video and then let us know which 2015 Mustang has your interest piqued the most - the EcoBoost four, the 5.0L V8 or the entry-level V6.

Ford starts GoDrive carsharing service in London

Automaker-supported carsharing services like BMW's DriveNow and Daimler's Car2Go are already well established in many cities around the world. Ford is no stranger to this business, either, with collaborations with companies like ZipCar in the US and Flinkster in Germany. Now, The Blue Oval is taking a new step by establishing its own dedicated offering in London called GoDrive. The operation is actually the expansion of an earlier 100-person pilot program and allows the automaker to test out ideas on a small scale. GoDrive is now growing to support 2,000 people in London, and they can share 50 vehicles that are scattered around 20 locations in the city. The fleet is split between Focus Electric models and Fiesta 1.0 EcoBoosts. One of the major selling points for the service is that users can take one-way trips through the city and have a guaranteed parking spot at their destination. Like any high-tech service today, much of the user interface for GoDrive works through a smartphone app that allows users to book cars and pay for trips. The driving is covered under an all-inclusive, pay-by-the-minute model, which includes London's congestion charge, and the first five minutes are free. To entice new users, the company is currently offering a free membership and 20 pounds ($31) in credit to sign up. GoDrive's small size also lets it gather and adjust to customer feedback quickly. For example, users reportedly enjoy getting to try out a vehicle with the latest infotainment and safety features. The company is already working on different pricing plans and parking options for the future, as well. The video below shows a little more the service in action.

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.
