2010 Ford Shelby GT500 gets two more MPG
Of course we’re fans of the new 540 hp Shelby GT500, but Ford may be reaching a little far in the latest press release. It wants us to know that the 2010 GT500 gets two more MPGs than the predecessor. What they forget to mention is the 20 MPG from the 2009 car (calling it a ten percent improvement would probably be too embarrassing.) But hey, every little bit helps.
Press release after the jump
The new 2010 Ford Shelby GT500 delivers the most power and refinement ever for a Ford SVT-tuned performance Mustang – and a few surprises, too.
“The new Shelby GT500 demonstrates Ford’s continuing commitment to high-performance vehicles,” said Derrick Kuzak, Ford group vice president, Global Product Development. “In addition to the numerous performance and refinement improvements inside and out, it’s also two miles per gallon more fuel efficient on the highway.”
“We’re proud of the many enhancements jointly developed by the Ford and Shelby Automobiles team that we’ve incorporated into the new model,” said Carroll Shelby, founder of Shelby Automobiles. “Building on what we learned to create the Shelby GT500KR, this new car offers a great combination of power, handling and braking. It is truly a special car that is a great deal of fun to drive.”
Ford’s Special Vehicle Team used the gains made on the Shelby GT500KR “King of the Road” Mustang as the performance starting point and built from there. The design team, with a nod to the original Shelby Cobra from the 1960s, takes those design cues even further with nuanced improvements in both the coupe and convertible, each of which boasts a more-refined interior.
“Working together on the KR, the Ford and Shelby teams developed new systems to continually improve the iconic Mustang,” stated Amy Boylan, president of Shelby Automobiles. “Those lessons learned are incorporated into the 2010 Shelby GT500. This approach will help maintain Mustang’s leadership position and make the ownership experience even more enjoyable.”
“The muscle car segment is becoming even more competitive,” said Jamal Hameedi, chief nameplate engineer for SVT. “We need to uphold the Mustang badge with honor, the Shelby badge with honor and most importantly the Ford badge with honor. This is the car that will do all of that.”
More horsepower, more refinement, more functionality
The combination of added horsepower, refinement and functionality makes the 2010 Shelby GT500 a unique high-performance car. It delivers more horsepower and more torque than the outgoing model, thanks in part to advancements pioneered on the GT500KR.
The 2010 Shelby GT500 is powered by a supercharged and intercooled 5.4-liter dual overhead cam V-8 engine that produces 540 horsepower at 6,200 rpm and 510 ft.-lb. of torque at 4,500 rpm. The redline is 6,250 rpm. The car’s aluminum power dome hood not only adds to the Shelby’s appearance, it helps cool the engine through a hood extractor.
The Shelby’s open-element air induction system features a conical air filter instead of a flat-panel closed system to reduce air restriction. This approach allows more air to be pumped through the engine, producing more power and increasing the engine’s efficiency. A cold-air intake feeds the coolest air possible directly into the air box, helping further increase horsepower. The intake necessitated moving the Cobra snake badge to the other side of the grille to enable maximum airflow.
The twin-disc clutch on the six-speed manual transmission has been significantly upgraded, improving drivability and NVH. The discs on the 2010 Shelby GT500 are larger – 250 mm in diameter compared with 215 mm in diameter on the outgoing model – and made of copper and fiberglass to make them more robust. A unique component of the twin-disc system is the control of the intermediate disc. Rather than floating, it instead has six straps that control the engagement of the clutch, improving drivability.
The 2010 Shelby GT500 offers customers improved straight-line acceleration, plus fuel savings when cruising on the highway in the top gears. Gears 1-4 remain the same, but fifth gear changes from .80 to .74 while sixth gear goes from .63 to .50, meaning that the 2010 Shelby GT500 will turn lower engine RPMs in those gears and deliver improved fuel efficiency. The new final drive ratio, moving from 3.31 to 3.55, enables the improved acceleration in lower gears while complementing the revised fifth and sixth gear ratios.
The Shelby’s distinct sounds will be apparent as always, though with new refinements, thanks to the work of the Noise, Vibration and Harshness (NVH) team. A patented resonator placed between the air filter and engine throttle body helps keep unwanted noise in check.
“You still hear the supercharger but not so that it’s intrusive,” said Kerry Baldori, chief functional engineer for SVT. “It’s the same with the exhaust. You want people to know you’re driving something special, but you don’t want an exhaust note that overpowers the whole interior.
“We spent a lot of time getting the right sound quality out of the exhaust so you get that nice, crisp Shelby sound outside and a pleasant sound inside the cabin. It’s a nice balance; one isn’t overpowering the other,” said Baldori.
Driving dynamics also are improved, thanks to SVT’s signature chassis tuning as well as new 19-inch Goodyear F1 Supercar tires and forged aluminum wheels on the 2010 Shelby GT500 coupe and 18s on the convertible.
Springs and dampers have been optimized for better roll control, giving customers more confidence when braking, accelerating or turning. The new chassis tuning takes its philosophy from the KR program, with a greater emphasis placed on primary body control. The team also stiffened the steering shaft.
“All our changes were about making the car respond as fast and as predictable as possible,” Hameedi said. “The 2010 Shelby GT500 conveys an athletic, confident feel. The shifter, clutch pedal, brake-pedal efforts and overall steering efforts are easier now. We wanted to make sure we had a nice, crisp short-throw shifter that was easy to go from gear to gear.”
The Goodyear F1 Supercar 19-inch tires have been upgraded, too. SVT members developed a “recipe” for the attributes and characteristics they wanted in the tire, which Goodyear’s team of engineers, designers and manufacturers brought to life. The result is better grip, better handling and better NVH properties, leading to a better customer experience.
The wheels themselves complement the high-performance nature of the 2010 Shelby GT500. The 19-inch wheels are forged aluminum wheels milled on both sides. The extra machining process creates “blade” spokes with very thin, yet strong, cross-sections. The spokes have a specific curve from the rim to the hub, not only for strength, but also to accentuate the offset and width of the tires.
The 2010 Shelby GT500 features AdvanceTrac®, Ford’s stability control system, with several options for performance. The default “on” mode accommodates every-day driving, and a Sport mode delivers for those wanting to put the Shelby GT500 through its paces on the track. The system also can be turned completely off, although the anti-lock brake system and other active safety systems remain in place. Standard safety equipment includes dual stage front air bags, side-impact air bags and Ford’s Personal Safety System®.
Numerous aerodynamic upgrades, including a redesigned splitter, were made to the front end of the 2010 Shelby GT500.
The team worked hard to get as much downforce with as little drag as possible, said Baldori. They worked to seal off the air that comes in the front so it can’t go under the car. A lot of time also was spent sealing components such as the radiator and intercooler to get rid of all leak paths. The result is an increased downforce, reduced drag and improved overall efficiency of the vehicle.
Directing the air so it’s used most efficiently was a painstaking process that ultimately will be rewarding to customers. The design of the front fascia and the car’s “flush” hood helps focus air flow. The top grille focuses air into the radiator, with a rubber flap inside the engine compartment helping to seal the system. The lower grille helps cool the intercooler.
SVT engineers also went as far to block off specific diamonds in the front of the 2010 Shelby GT500’s distinctive grille to help maintain the correct cooling and aerodynamic balance.
