The New Shelby GT500 Is Coming in Two Weeks


If you've been paying attention in 2018, you probably already know that a brand new S550 Mustang Shelby GT500 is coming this year. And there is good reason to believe that the 2019 North American Auto Show (often referred to as the Detroit Auto Show) in less than two weeks will host the debut of the GT500. Why the 2019 Detroit Auto Show? It's one of the biggest auto shows for Ford. Ford decided to reveal its Ford GT at the same show three years ago in 2015, and also threw in the current Shelby GT350R and the current F-150 Raptor for good measure.

The Shelby GT500 has already been confirmed by Ford and teased in a couple of pictures and videos. Why is the GT500 significant? The first Shelby GT500 was a 1967 model and it was developed with help from the legend himself, Carroll Shelby. Because of Shelby's personal involvement in racing at the time, the original Shelby GT500 was actually meant to be a track monster, not only a straight line car. It used a a modified version of the massive 427 cu.in. (cubic inch - 7.0 litre) naturally aspirated V8 Shelby developed for the original GT40 to win at Le Mans. Several (functional) aerodynamic bits were added and a bunch of body parts were made out of fibreglass to save weight.


Ford sold Mustang Shelby GT500's for only a couple more years back then, ending production in 1969. That hallowed Shelby GT500 name didn't return to the Mustang lineup until the 5th generation (code named S197) in 2007 - a full 40 years after the original. But by that time, it had a lazier supercharged V8 making a nice and round 500 hp. No attempt to save weight was made at the time. Just like any S197 Mustang, it could be made into a serious track car with huge aftermarket support but, although it handled very competently from the factory for something weighing nearly 2 tonnes with a solid rear axle, it was much more of a Grand Tourer and a straight line bruiser than a track honed machine (not to say it couldn't be enjoyed on track...).

By the end of its production run in 2014, the S197 Shelby GT500 had gone through a couple of refreshes and engine changes. The 2013-2014 model was making 662 hp out of the Trinity supercharged 5.8 litre V8, making it the most powerful production V8 at the time. Although it still handled well for what it was, it was still very much a bruiser. This time, though, I think it'll be different.

The headline for this car is "700+ hp" so we know that all is still well at Ford and huge hp numbers haven't died yet. Chances are, it will be higher than the Dodge Challenger Hellcat, which makes 707 hp in the "standard version" (there is now a Redeye version making 797 hp, because 707 hp isn't enough). That said, the GT500 should be approx. 200 kg (400+ lb.) lighter than the Challenger so it shouldn't need as much hp to go just as fast. As for the power source, Ford already confirmed that a hybrid Mustang is coming in 2020, which will be more efficient than a V8, so this will likely use a traditional powertrain running on nothing but dinosaur juice.


Rumour has it, it will be a supercharged version of the GT350 5.2 litre V8, but it might switch back to a traditional cross-plane crankshaft here instead of the flat-plane crankshaft that helps the naturally aspirated GT350 version rev to over 8,200 rpm. A manual gearbox is probably guaranteed, but it will likely be offered with an automatic as an option, the 10-speed auto already used on the Mustang GT; a first for a GT500.


However, while the last 662 hp GT500 came with hopelessly undersized 265-section front and 285-section rear tires, Ford hasn't shied away from wide tires recently. The Shelby GT350R, for instance, uses 305-section front and 315-section rear tires. Even the more pedestrian Mustang GT Performance Pack Level 2 (PP2) comes with 305-section Michelin Pilot Sport Cup 2 tires all around. Moreover, the bits Ford teased so far appear to show functional aero bits such as a front splitter and a very good size pedestal spoiler similar to the one on the track-special Shelby GT350R. Finally, Ford now uses the same sort of magnetorheological dampers that cars like the Corvette, Ferrari 488, Audi R8, Lamborghini Aventador, etc. in the relatively pedestrian Mustang GT, so it'll likely be offered here as well. That should allow for to keep the GT500 reasonably comfortable on the road, yet be able to transform into a pavement pounding machine at the press of a button. It certainly won't be a hardcore track car. That's the GT350R's job. But I suspect that all of this will make this the best handling and most composed GT500 ever (by far).

And in two weeks, we should see it in all its glory. In the mean time, short of a couple of leaked pictures from dealer events, the teaser video below is the most Ford has given us so it'll have to do until the 2019 Detroit Auto Show.

GTR vs Evo X vs STI: which has the best AWD system?

A few weeks ago, I made a post explaining  mainstream AWD system types and how they compare , pros and cons, etc. including some simple diagrams to show where the power goes and how much. As promised, this post will focus on specific cars and what AWD systems they use, especially ones that that have more or less been defined by their AWD systems, and the best place to start may be with a bombshell; the Nissan GT-R. Nissan GT-R (R35) The GT-R has built a reputation around having monster traction and very approachable performance, thanks to its AWD system - Advanced Total Traction Engineering System for All-Terrain (ATTESA) - and what it can do for you. But the GT-R doesn't actually use the most mechanically sophisticated type of AWD systems discussed in the previous article, namely a "true" AWD with a centre differential. Instead, it uses a clutch pack to transfer power. RWD-based clutch-type AWD schematic - Rams Eye The Track Guy © The R32, R33, and R34 Sky

Michelin Pilot Super Sports vs Firestone Firehawk Indy 500 - Street Review

I've been a huge fan of Michelin PSS tires and exclusively bought them for the Mustang over the last four years. So how did I end up here? This year, I was hugely interested in trying an "R-comp" tire. I had my eyes set on Bridgestone Potenza RE-71R's for two simple reasons: price and reputation. Although not a true "R-comp" tire on paper, it performs like one by the account of every single test and review I've read (down to wear rates...). They seem like they're easily the most affordable (from a big brand) R-comp tire and combine that with a reputation for having tons of grip, it was an easy top contender. I had my concerns, though. For one, I'm told and have read that they are an autox tire, not really designed for high speed, pressure, and temps associated with open track. For another, the Mustang is a heavy car (as far as track cars are concerned) being roughly 3,800 lb. (including driver), which will amplify the unwanted open track load

Michelin Pilot Sport Cup 2's vs Bridgestone Potenza RE-71R's

I never thought I'd ever run Michelin Pilot Sport Cup 2's on my 2012 Boss 302. The cost is astronomical and they are supposed to last the least of anything comparable. So how did I end up with (nearly) fresh Sport Cup 2's? A complete fluke. I came across a lightly used set with only a few hundred miles and no track time; 305/30/19 takeoffs from a GT Performance Pack Level 2 (GT PPL2). I knew my 71R's were getting very worn before the season started and likely wouldn't last the whole season, even this short one. The price was far better than a new set of RE-71R's, a little more than half, and local Time Attack rules (Canadian Automobile Sport Clubs) recently made 180 and 200 TW tires equivalent, meaning no PAX or PIP point penalty for going with 180 TW tire like the Pilot Sport Cup 2's. I have been very curious about how PSC2's compare to RE 71R's but I stayed away due to their being painfully expensive and, up to last year, their 180 TW rating would

Michelin PSS vs Firestone Indy 500 - Track Review

A couple of weeks ago, I posted my first impressions of Michelin's PSS vs Firestone Firehawk Indy 500 tires. I've run PSS's for several years on the Boss, but I'm trying the Indy 500's for the first time. In short, I was worried about the narrower tires (I was running 285/35/18 PSS but could only find the Indy 500 in 275/35/18) and tread squirm, but I was happy with them up to that point just driving on the street. I had the chance to drive on them for three track days now. So what were they like? After my first session, they made an impression that basically persisted for the rest of track sessions on them. Phenomenal, unmatched value. Now, if value is something that stands out above all else, it typically means the compromise between qualities you want and those you don't is less than ideal, but the value is attractive. This is no different. I'll start with the bad, which really boil down to two: ultimate grip and grip longevity. Grip is noticeably l
