2020 Ford Mustang Shelby GT500: 12 Tech Tidbits

Cars dont get into the 700 clubwith factory warranties, at leastuntil a ton of serious engineering happens. Here are a dozen highlights of those efforts. --> Supercharged The blowers 2.7-liter displacement is more than half that of the engine! It nestles as deep as possible in the valley of the vee, with the screws on the bottom pushing air up into the intercooler and then back down into the cylinders. No word yet on horsepower consumption of the supercharger, but suffice to say the cylinders are likely producing upward of 1,000 ponies in order to net out 700-plus at the crank. Port Injected The supercharger hogs all the room where the direct-injection fuel rail would go. An engine-tuning simplifiernot sending it to Europe, where getting an exhaust particulate filter to pass durability requirements would have been problematic. Crated Yes Virginia, there will be a crate engine offered. But not for a little while because work on that variant cant begin until final certification of the production version is completed later this year. The Ford Performance Parts catalogue could begin offering other parts, however, like the stronger bolts and block for drag racing use. Strengthened Coping with in-cylinder pressures of more than 2,000 psi required longer, stronger cylinder head bolts, stiffer valve springs, hardened valve seats, and structural ribbing on the cylinder block. Lubed Handling what is expected to be much higher dynamic driving limits required a complex set of oil pan baffles, including some that are activehinged to close at certain times and open at others. Cooled Air rushing into the gigantic central grille passes through the intercooler circuits radiator first, then through the A/C condenser, then through the engine radiator. An auxiliary side-mounted engine coolant radiator gets first crack at the cool air on the passenger side, while a matching radiator on the driver side cools the engine oil. The twin-clutch transmission gets a small horizontally placed radiator grabbing air off the splitter below the main radiator stack. Braced Connecting the strut towers for ultimate handling stability while clearing the gigantic supercharger is the job of a computer-optimized piece of magnesium sculpture. 7 DCT Why not use the 10-speed automatic? The transmissions weigh about the same, and both have minimal parasitic loss. Torque capacity is the differentiator. The GT supercars twin-clutch transmission internals were already beefy enough, and reinforcing the 10-speed would have been costly and unnecessary. The seven-speeds first gear is about the same as the 10-speeds second, the top gear ratios are roughly equivalent, and this engine hardly needs any torque multiplication to launch stoutly. Oh, and the extra gear ratio steps are unnecessary in a car with this ones performance and fuel ahem , economyexpectations. Rotary Shifter?! It doesnt look sporty, but rather than looking at the shifter, look at the custom shift paddles, which are not shared with other Mustangs. Theyre derived from the Raptors. Vectoring Torque To withstand the incredible torque routing aft, the GT500 gets a carbon-fiber driveshaft. (The GT350 doesnt get this.) The differential features a Torsen mechanical limited-slip unit, running a 3.73:1 ratio. The rear halfshafts are also considerably beefier, but the wheel rims do not have knurling like a Nissan GT-R . Chassis Tuning The base car is expected to attract more sophisticated customers who dont want to be punished, so its tuning is a little more touring oriented than the GT350 Rs. The track package/carbon-fiber package rides slightly stiffer. Carbon Exposed The pricey carbon-fiber wheels represent a giant step forward for this technology on the part of Australian supplier Carbon Revolution. These wider 20-inch wheels manage to weigh slightly less than the GT350s 19s, but that wasnt the hardest part. Developing a process to hand lay the carbon fiber so that it looks good enough to leave exposed took some real doing. That accounts for a good bit of the price, and Wheel Doctor cant help you if you curb one of these babies. Thats why owners who drive their cars frequently tend to own a second set of tires and wheels, reserving the originals for show/track use.
