Early reports of the 2015 Ford Mustang EcoBoost hinted at the notion that the power figures would be significantly lower when an owner filled up with 87 octane fuel. When running the good stuff, the EcoBoost engine produces 310 horsepower and 320 pound-feet of torque. Should you decide to fill up with 87, you can expect a power output of 275 horsepower and 300 pound-feet of torque, at least that's according to a Ford training manual obtained by Mustang6G.

If you're filling up your turbocharged Mustang with 87, you deserve less power as it should be clear that such a motor wants to drink the good stuff. Yes, the car is capable of running on 87 with no issues, but just be ready to be a bit slower. This is why you see disclaimers in car ads, because automakers get their best horsepower ratings when they run higher-test fuel.

Now, this should be even less of a surprise with the EcoBoost Mustang because a Ford Motor Company [NYSE:F] engineer allegedly came out and said to expect a 13% power loss. The actual power loss figures shown above aren't that dramatic. The horsepower figure is down 11.3% and the torque is down 6.3%.

The moral of the story? Gas is cheap right now, so enjoy the better fuel and make your Mustang happy.

When the all-new Ford Mustang Shelby GT350 goes on sale later this year, a few lucky buyers will be able to get their hands on an ultra-collectible 2015 model year example, which the Ford Motor Company [NYSE:F] is building to celebrate the 50th anniversary of the original Shelby GT350 launched back in 1965. Just 137 examples bearing a 2015 VIN will be built before production switches over to 2016 model year cars.

Of these 137 cars, 100 will be the Shelby GT350 and the remaining 37 cars will be the more hardcore Shelby GT350R. Why such an odd number for the GT350Rs? Because back in the 1960s, Shelby American founder Carroll Shelby insisted that two prototype versions of the original FIA-homologated GT350R be built along with 35 production examples. While most records show that only 34 production models received serial numbers from Shelby, Ford will now build 37 2015-spec GT350Rs in Carroll Shelby’s memory.

As for the 100 2015-spec GT350s, Ford has confirmed that half of these will be equipped with the car’s available Technology Package and the remaining half will get the Track Package. The tech package adds things like power-adjustable seats, an upgraded audio system, an 8.0-inch touchscreen display and dual-zone climate control. The track package, meanwhile, adds things like magnetic ride suspension, stiffer springs and additional coolers.

Full pricing and specs are yet to be announced but pricing for new GT350 is expected to start at about $53k and peak output from the car’s new 5.2-liter, flat-plane crank V-8 should be more than 520 horsepower.

“Fans of the Shelby brand are among the most passionate in the automotive industry,” Ford Performance marketing manager Henry Ford III said in a statement. “To honor the passion of our fans for Shelby GT350’s 50th anniversary, a limited run of GT350 models will be built in 2015—these cars will be highly coveted by both Mustang and Shelby enthusiasts alike.”

Turn signal indicators located in hood vents – a heritage cue from the 1967 Ford Mustang – return as standard equipment for 2016 Ford Mustang GT

Exclusive California Special Package for Mustang GT Premium available this fall; Pony Package available for Mustang EcoBoost® Premium by year’s end

2016 Mustang GT convertible will be available with the Performance Package

For the 2016 model year, Mustang fastback and convertible welcome the return of the iconic California Special Package and Pony Package —two iconic Mustang trim levels made popular in the 1960s. Several other new options, including new stripes and wheels, allow owners to make their pony car as individual as they are.

Fans have been clamoring for the return of hood vent-integrated turn signals for years, and in a nod to heritage Ford is honoring the request, bringing back the popular feature as standard equipment for owners of the 2016 Mustang GT. First offered on the 1967 Mustang, secondary indicators in the hood vents would come to represent an iconic piece of pony car DNA. Now, this segment-exclusive feature will serve as an additional “heads-up” for Mustang GT drivers.

“Mustang enthusiasts are not shy about telling us what they want,” said Melanie Banker, Mustang marketing manager, “and we’re constantly exploring ideas together with our engineering team to develop new features we know our customers will love. These new hood vent indicators for the GT model are a perfect example of us communicating customer feedback to Mustang engineers and the team responding with an exclusive new feature for owners of the 2016 Mustang GT.”

New stripes, wheels, trims allow for greater personalization

Several new packages and options will be available for 2016 Mustang GT and Mustang EcoBoost® when the cars arrive in dealerships in the third quarter of 2015. Returning to the sixth-generation Mustang are over-the-top racing stripes direct from the factory. Offered in black or silver, the stripes are available on most color and trim packages.

Last seen on the Boss 302, a painted black roof option is now available for the EcoBoost-equipped Mustang and Mustang GT.

Exclusive to Mustang EcoBoost Premium is a fresh take on the Pony Package. With unique 19-inch polished aluminum wheels, tri-bar pony logo on the grille, side stripe and chrome window surround, the fastback Mustang with Pony Package is sure to stand out from the crowd when it arrives in late 2015.

For customers after a stealthier look, Mustang GT will offer a Black Accent Package this fall. Fastback and convertible Mustang GT models with this package will showcase special 19-inch black-painted alloy wheels, black decklid spoiler, dark taillamp trim, and 5.0 and pony logos in black.

Mustang GT Premium owners can order the California Special Package with a host of features including:

19-inch ebony-painted machined aluminum wheels
Ebony leather/Miko suede seat inserts with red contrast stitching and embossed logo
Unique door panel inserts and premium carpet featuring red contrast stitching
Unique aluminum dashboard finish with California Special badge
Hood and side stripes
Black pedestal spoiler
Unique faux gas cap
Strut tower brace with unique California Special badging
Dark taillamp accents
Black-painted mirrors, hood vents
Performance front splitter
Unique grille with tri-bar pony logo
Mustang drop-top aims for tip-top performance
Now, just like owners of the fastback model, customers of Mustang GT convertible equipped with manual transmission can order a Performance Package for 2016. Featuring increased structural bracing, as well as revised suspension components, brakes, wheels and tires, Mustang GT convertible equipped with Performance Package will be a force to be reckoned with – both on back roads and at the track. Features include:

Unique chassis tuning, with strut tower brace and K-brace
Larger radiator
Revised suspension with upsized rear sway bar, heavy-duty front springs
Six-piston Brembo front brake calipers
19x9-inch front, 19x9.5-inch rear ebony-painted aluminum wheels with summer tires

“Ford Mustang GT fastback with Performance Package has been very popular,” said Banker. “Customer feedback indicated a strong desire for the package on the convertible model as well, and the 2016 Mustang GT delivers.”
