2011 Ford Shelby GT500 eventually gets aluminum engine, loses 120 pounds
Ever given Ford introduced the complicated Shelby GT500 4 years ago, almost no one has complained about the supernatural energy levels produced by the supercharged 5.4-liter V8. With as much as 540 horsepower and 510 pound-feet of torque in the 2010 indication, there was no necessity of deepgrown. No, a issue was an additional of mass.
Prior to the contemporary GT500 was innate, Ford had a blown aluminum retard 5.4-liter V8 in a short lived GT supercar. However, when a engineers at Ford’s Special Car Team developed a GT500, they opted to mountain the GT’s cylinder heads on a expel iron block used in a big F-Series pickup trucks. After debuting the visual refresh for a Mustang a year ago, Ford has spent a final two months announcing fresh brandnew powertrains for the base and GT models. That process has now come full circle with SVT rolling out the heart medicaloperation for a Shelby GT500. A 2011 model eventually has a aluminum powerplant you all longedfor when it debuted, and a effect is positively en-lightening. Review on to find out more.

The SVT engineers actually had the reason for going with the iron block in a initial place. Mustangs like a GT500 as well as its Cobra ancestors often finish up being heavily mutated for make use of at draw towards strips and race marks, and the SVT organisation wanted to make certain a customary retard could mount up to a rigors of those significantly aloft outputs. They chose not to use an aluminum retard until they had a chance to develop one with the same strength as the iron version, and which time has rightaway come.
You notlongago had a possibility to sit down with GT500 arch nameplate operative Jamal Hameedi in his office during SVT’s domicile to learn more about what’s brandnew for 2011. Switching to an aluminum retard was a bit more complicated than simply digging out a casting molds that were used for a GT. The engine in which 200+ mph supercar used a dry sump lubrication system as well as featured iron cylinder liners. A new GT500 engine is derived from the structural design of the older block but retains a wet sump complement used in alternative Mustangs. The real magic is something that most owners will likely never actually see.
Last Jun you learned about an award that several Ford researchers had received for a cylinder gimlet cloaking complement they grown called a Plasma Eliminated Wire Arc (PTWA) process. The Ford press recover at a time framed a award in term s of fuel potency as well as gave no real spirit about what was about to come. It rightaway turns out that a first production Ford to make use of the PTWA process will be the 2011 GT500.
Nissan actually licensed PTWA from Ford for use upon the V6 engine in a GT-R.The heart of a PTWA routine involves stuff oneself the steel wire into the device which heats it up to 35,000 degrees Fahrenheit and then sprays it onto a aluminum cylinder bores. Ford is not actually the first company to use the process similarto this. Similar mechanisms have been used to coat a fan blades in jet engines for the series of years. Asingle of the primary differences is which Ford is regulating PTWA with the required steel alloy rather than alittle super exotic aerospace materi al. Ford isn’t even a first automaker to use this specific coating routine. That honor falls to Nissan, which essentially protected the record from Ford for make use of on its V6 engine in a GT-R.
Hameedi believes that Ford has an important value over Nissan. Anybody that has ever used the teflon-coated vessel is informed with a complaint of the non-stick coating bark off ove r time. In the past BMW has also had issues with a nickasil coatings betimes separating on some of its aluminum blocks. Removing any separate materials to adhere to any other is regularly a complaint, so a primary aspect has to be specifically prepared in order for the coating to have something to hang on to. Nissan protected Ford’s coating record though used the own aspect credentials routine. According to Hameedi, Ford’s aspect preparation works so well which e ven after engines have left through the full continuance cycle a bores still look similarto brandnew.
Regulating a PTWA process allows a block to have a thinner aspect coating – only 150 microns deep – that is just as tough as asingle with expel or pressed-in iron or steel liners. However, using less material results in reduce weight. According to Hameedi, the GT500 block is 8.5 pounds lighter than a sleeved GT version. Overall, the finish engine is 102 pounds lighter than the 2010 cast iron engine. The steel cloaking has also helped Ford revoke the internal friction of the engine, aiding both potency and power production.
Hameedi explained that some draw towards racers complained of power dump off on wet summer days, that was attributed to reduced feverishness transfer potency. SVT addressed this with the incomparable intercooler that helps the engine deliver some-more unchanging energy over the entire operating range as well as under dissimilar environmental co nditions. Hameedi tells Autobl og that a brandnew aluminum block engine should be means to survive “d uring least” as most limit power in modified form as the iron block equivalent. Additionally aiding respirating is a larger exhaust complement with 2.75 in. header pipes like those upon a brandnew 5.0-liter in a Mustang GT. Out of the box, a new powerplant delivers 10 more horsepower bringing a total up to 550 hp with a same peak torque of 510 pound-feet. Eighty percent of which torque is available everywhere between 1,750 rpm as well as 6,250 rpm.
For 2011, Hameedi tells us “We’re at a top of a power store, we’re the fastest accelerating vehicle, so this really wasn’t about going any faster in the true line. This was about mending the weight placement as well as handling of the car.” A new engine contributed to a 120 pound overall weight reduction with many of that coming off the front axle. Most of a rest of a weight loss came from new lighter weight wheels that are part of the SVT Opening Package. The front wheels that come with a Opening Package remain 19 inches in hole but have been 4.7 pounds lighter. The rears grow to 20 inches but are still 2.8 pounds lighter. Cutting unsprung mass is never the bad thing when it comes to both ride quality and handling. Along with a extra back grip supposing by the incomparable Performance Package wheels as well as tires, SVT has combined the 3.73:1 back axle comparativemeasure.
The 2011 GT500 is three seconds faster around a certain un-named northern California racetrack.Like other 2011 Mustangs, a GT500 gets the brandnew electric power support steering (EPAS) system that Hameedi describes as “extremely precise.” During parking lot speeds, he describes a steering effort as Lincoln-like but it fast builds up as you expostulate some-more aggressively as well as it supposedly has excellent on-center feel, something that is often difficult to achieve with EPAS. We’ll have to wait the few more months to find out only how precise which is since we won’t get to drive the car until Open.
Removing any high-powered car to accelerate, stop or turn is rarely dependent upon the adhe sion in between the tire and the highway surface, generally when it’s wet. SVT has adopted a latest generation Goodyear F1 supercar tires for the 2011 GT500, which Hameedi says are “the major step” beyond a prior version in both wet and dry grip. With the reduced mass upon the front axle, SVT has also mutated a spring and check rates on both base and Performance Package models. The latter chronicle get s 20.5-percent stiffer front springs and 9.5-percent tighter rears that also bring a front finish 11 millimeters closer to a road as well as the rear 8 mm lower.
One of the main criticisms of the Mustang convertible ever given a S197 debuted for 2005 (actually ever given flattering most forever) is the lack of structural firmness. Because of which flexibility, the 2010 model GT500 automobile was essentially considered more of a cruiser model as well as was thus tuned some-more for float joy than doing. Thus the old convertible was only available with 18-inch wheels. For 2011, SVT took the lead upon building an upgraded body structure for a convertibles that should help keep the corners of a automobile from moving relative to each alternative. The effort was successful enough that the changes are bein g implemented opposite the house on all 2011 Mustang convertibles. A 2011 GT500 automobile additionally gets bumped up to the 19-inch wheels as well as offers handling that is supposedly much closer to the coupe without degrading the ride comfort.
For those who wish a sun to shine but still wish the extra stiffness of a coupe, the GT500 is now accessible with a glass rooftiles that has been accessible on unchanging Mustangs for a past two years.
Regardless of a rooftiles type, Hameedi tells us which a GT500 has “the really different driving knowledge driving an ‘11 from the ‘10, they’re most some-more nimble, they feel some-more alive, the steering is quicker.” The straight-line acceleration was softened by about 1/10th of second, but overall drivability as well as handling have been said to be vastly improved. A upgrades have been far some-more apparent upon the road march than they are during the drag strip. According to SVT spokesman Patrick Hespen, the 2011 GT500 model is three seconds the path faster than a 2010 around a sure un-named 2.3-mile- long, northern California racetrack which happens to play host to the large historic racing eventuality every August. Clo ser to home during Grattan raceway in west Michigan, the 2011 GT500 is additionally about 2.5-3 seconds the lap faster. Since a relatively modest power enlarge, those have been some big numbers.
A Opening Package also gets some modest visual differentiators including narrower racing stripes down the center of a body along with the new wheel design. Inside the car, the change knob on a Opening Package model lacks the stripes found upon the base indication.
Whilst most GT500 drivers have been unlikely to be too concerned about fuel potency, it is a political as well as commercial reality that Ford does have to understanding with. The EPA rated the 2010 GT500 at 14 mpg city and 22 mpg highway and slapped a $1,000 gas guzzler taxation upon a metalcover. The further of EPAS, reduced mass and markeddown friction all helped to improve the 2011 GT500’s EPA numbers to 15 and 23 mpg and privileged a GT500 of the dreaded guzzler tag.
Eventually, just like the brandnew 2011 V6 and GT Mustangs, the GT500 will go into production this Spring with an on-sale date before Summer. We’ll be anxiously available the first time at the back of the wheel of the 2011 Ford Shelby GT500, though until then you can peruse Ford’s central press release for more sum as well as crop the high-res picture galleries.

DEARBORN, Mich., Feb. 8, 2010 – Ford’s Special Vehicle Group (SVT) engineers have been taking tall performance to the brandnew level with the 2011 Ford Shelby GT500, ensuing in a car which has an all-new aluminum-block engine, even better driving dynamics and handling, softened fuel economy as well as more horsepower than ever.
“The SVT group continues to pull the performance standards of the Shelby to even higher levels as well as better refinement,” pronounced Jost Capito, executive of global performance vehicles and motorsports business developmen t. “All the changes we done reflect a enterprise for even better handling as well as outstanding driving dynamics – from weight assets to softened change.”
Weight savings, brandnew record title all-new aluminum engine
A 2011 Shelby GT500 is powered by an all-new aluminum-block 5.4-liter supercharged V-8 engine, which produces 550 horsepower and 510 ft.-lb. of torque, a 10 horsepower increase versus the 2010 model. The engine also is 102 pounds lighter than its prototype, delivering a better power-to-weight comparativemeasure, softened fuel saving, increase in speed, doing as well as steering precision.
“Slicing weight to improve opening is a convention between hot rodders,” said Carroll Shelby, founder of Shelby American. “It might not be as sexy as adding some-more horsepower or bigger brakes, but shaving pounds off of the car is the single smartest pierce you can have.”
The new engine uses state-of-the-art Plasma Eliminated Handle Arc (PTWA) ship coating, a process that applies the 150-micron composite coating that contains nanoparticles upon the internal surfaces of engine cylinder bores, replacing cast-iron liners typically used in aluminum engine blocks. A Egghead Skill Owners Education Foundation respected the inventors of a Ford-patented PTWA technology with the 2009 Inhabitant Inventor of the Year Award.
This is the initial Ford application of a record, and it offers improved altogether performance as well as durability, along with organic benefits of markeddown friction between piston rings as well as cylinder bores, softened feverishness transfer due to increasing aspect hit area as well as the weight assets of 8.5 pounds compared to a standard steel-sleeved aluminum block. THE automatic roughening process provides aloft element adhesion for a spray coating.
A PTWA process use s air and electrical energy to emanate a plasma jet of 35,000 degrees Fahrenheit, which melts a steel handle that is fed into a rotating spray gun. Regulating atomized air, a melted steel wire is blown into the specially machined surface of the aluminum-block engine cylinder bore. In the routine of melting and applying a steel to the surface, the steel wire oxidizes, creating the combination cloaking consisting of both iron as well as iron oxide.
“Ford’s Global Investigate as well as Modernized Engineering looks to all industries for advanced technologies – and this comes from aerospace. It’s the same record you would find upon aircraft engines,” said Glenn Jorgensen, SVT powertrain group leader. “We’ve invented the cloaking as the replacement for expel iron that delivers impro vements in power and opening and fuel economy.”
The new engine also has its roots in a iconic Ford GT. A new 5.4-liter engine is an expansion of the GT engine, with improved retard structure by the make use of of a singular bulkhead chilled process as well as six-bolt shelter main bearing caps. This brandnew advanced engine will surpass Ford GT performance with the normal supercharger record.
“The Ford GT has solidified itself as one of a world’s many desired supercars. To make improvements to the engine from this supercar as well as have it accessible in a Mustang is impressive,” said Kerry Baldori, SVT tellurian performance vehicle arch functional engineer. “The aluminum-block engine is strong as well as clever enough to produce the performance numbers as well as durability the customers demand.”
Increasing power and increased fuel saving
The 2011 Shelby GT500 combines energy as well as fuel economy into one considerable package. This 2011 Shelby GT500 will be the first modern Shelby without a gas guzzler tax, than ks to the EPA-projected 23 mpg mainroad and 15 mpg city it will deliver. This is up from 22 mpg mainroad as well as 14 mpg city for the 2010 indication.
The 5.4-liter V-8 achieves 80 percent of the torque between 1,750 as well as 6,250 rpm, giving the automobile the aloft level of opening feel. A larger two-row intercooler for a supercharger system has 40 percent more cooling capacity, helping to make power more unchanging in aloft ambient conditions.
Fuel saving gains come from the new 102-pound-lighter aluminum-block engine, EPAS and detailed aerodynamic changes to the underside of the car.
Thespian opening upgrades
New for 2011 is an SVT Opening Package for enthusiasts who want even more opening out of their Shelby GT500 for racetrack-ready driving dynamics. Finish with all-new Goodyear Eagle® F1 SuperCar G: 2 tires that SVT engineers worked without delay with Goodyear to develop, a automobile is ready to race. The tires offer superb dry traction and accurate handling, complete with the race-inspired high-performance step devalue.
The optional package additionally offers singular styling, lighter wheels, a higher back spindle ratio and stiffer springs, as well as it is available on both a convertible and coupe. Data show a 2011 coupe with the SVT Performance Package is 3.0 seconds faster per path than the 2010 Shelby GT500 on the 2.3-mile exam track.
Carried over from 2010, a 2011 Shelby GT500 facilities AdvanceTrac®, Ford’s stability control complement with several options for opening. Calibration of a complement for a 2011 Shelby has been singly tailored to each car pattern Bottom or discretionary to optimize the performance.
SVT has worked really hard to make EPA S better than a effusive hydraulic steering complement. A further of EPAS creates for the thespian grant to Shelby GT500 driving dynamics, with softened torque build-up and highway feel which delivers quicker and more accurate steering, increased bid upon a racetrack or circuitous roads, and markeddown effort in low-speed parking maneuvers.
Slotted stop dust shields were combined to improve stop cooling as well as doing, and the new ped al box improves clutch and pedal efforts even some-more. A lowered float height of 11 millimeters in front and 8 millimeters at the rear provides a sportier attitude and improved handling.
More engine sound, less road noise For 2011, Shelby GT500 also benefits from NVH Sound, vibration as well as harshness) improvements. Altogether road sound is reduced by 20 percent contra a 2010 Shelby. Actions undertaken to achieve this improvement include additio nal sound-deadening material on either side of a instrument panel, one more receptivetoadvice absorption at the back of interior trim panels, and a rear circle arch ship to reduce sound upon gravel or soppy surfaces – all ensuing in the motorist hearing more empty and engine sound as well as reduction highway as well as air sound.
The Shelby GT500 convertible indication facilities extended structural rigidity, with parallel rigidity improved by 12 percent contra a 2010 model. The V-brace has been stiffened by adding gussets. The delegate crossmember also has been stiffened, whilst a front Z-brace has been added, connecting primary and secondary crossmembers. A-pillar stiffening foam has been added to increase acerbity.
The constructional improvements to a automobile gave SVT a event to be some-more sport-oriented in a framework tuning, but trading joy. Along with a chassis and structural improvements, the 2011 model also will get customary 19-inch aluminum wheels.
“Asingle of the biggest changes for this Shelby is which a automobile acts as well as feels similarto a coupe,” said Jamal Hameedi, SVT arch nameplate engineer. “Before, they had the very different impression, as well as a automobile is taking the large step in a sportiness and handling precision area, without degrading the ride.”
GT500 gets a new empty for 2011, roaring with an even some-more assertive sound than a 2010 indication. A 2.75-inch empty with all-new tuning helped to deliver the one more 10 horsepower.
Combined preference content
New for 2011 is an discretionary potion roof, providing customers with the less expensive option than a convertible and without compromising the coupe’s versatility, headroom or climate-controlled environment.
A specially formulated potion additionally protects interior fabric material from solar radiation deterioration and blemish by reducing solar light transmittance. To help improve acoustics and interior serenity, a glass facilities a layer of vinyl that reduces sound, vibration as well as harshness.
Other new convenience technologies include:Standard HID (high-intensity liberate headlampsMyKey™ programmable car keyIntegrated watchman mirrorFold-down back headrests”Whether you’re look ing to take a GT500 out on a streets or have some fun during the track,” Capito says, “this car will prove the many discriminating performance pushing enthusiasts.”
