Once we consider vehicles, we do our greatest to evaluate them by what they’re, not criticize them for what they aren’t. However within the case of the most recent Mustang Darkish Horse, our explicit pattern was noticeably let down by a key omission.
The Darkish Horse is–at the very least till the insane Mustang GTD drops–the gnarliest pony in Ford’s secure, with a 5.0-liter Coyote V8 cranking out 500 horsepower and 418 lb.-ft. of torque by both a Tremec six-speed handbook or, as present in our check automotive, a 10-speed computerized.
[Ford Mustang GTD: 815 horsepower–more per liter than a 911 GTS RS]
The Mustang Darkish Horse will get some particular trim each in and out, however the actual pleasure is the five hundred horsepower beneath the hood in addition to the out there Dealing with Package deal (not pictured, sadly).
Brakes are additionally totally as much as no matter you’ll be able to throw at them, with huge 15.3-inch, two-piece rotors up entrance and 14-inch rotors within the again. Calipers are six- and four-piston Brembos, respectively. It’s a full, track-capable brake bundle.
The $69,715 Darkish Horse additionally will get Ford’s MagneRide dampers normal, with particular Darkish Horse tuning for the shocks in addition to Darkish Horse-specific springs and anti-roll bars. Supplemental coolers for engine oil, transmission fluid and differential oil are additionally among the many severe, track-focused bits.
Critical, that’s, till you get to the wheels and tires. The elective $5495 Dealing with Package deal features a set of 19×10.5- and 19×11-inch wheels wrapped in some lethal severe Pirelli P Zero Trofeo RS 180tw tires: 305mm fronts and 315mm rears. That’s a severe assertion of intent.
The Dealing with Package deal additionally consists of particular suspension settings to benefit from these meaty tires, tow hooks and a spoiler with a Gurney flap–all prepared to your subsequent monitor day.
Sadly, our check automotive didn’t come outfitted with mentioned Dealing with Package deal.
Once more, we don’t wish to dunk on the Darkish Horse for what it isn’t, however on the identical time, the bottom wheel-and-tire bundle does a real disservice to what’s in any other case a really competent chassis. The usual 19×9.5- and 19×10-inch wheels with 255/275 rubber are merely not sufficient rubber on the bottom to tame a 500-horsepower, 3996-pound automotive.
If we have been to learn an implication into this example, we’d say that Ford understands that lots of its patrons will likely be including their very own wheel-and-tire packages, permitting the usual automotive to function the right clean canvas. Or it supplies an choice for homeowners who by no means intend to take their Darkish Horse to the monitor however nonetheless wish to order the baddest Mustang on the menu–and, on the identical time, don’t wish to drop $2500-plus on tires each 6000 miles.
Regardless, the non-Dealing with Package deal Darkish Horse is a letdown. Regardless of inherent chassis goodness and a stout engine, the upsides can not shine by the weak wheel-and-tire bundle.
A 2-ton automotive is rarely going to really feel nimble, however Mustangs for the reason that S197 have been blessed with significantly good steering suggestions (yeah, we mentioned what we mentioned and we stick by it), and this raddest of S650s isn’t any exception. The steering and chassis really feel ok to let you understand precisely what the tires are doing, which, after all, isn’t a lot. It makes the automotive straightforward and enjoyable to slip round because it’s so controllable, however the lack of grip is simply extra disappointing due to it.
Brakes are as much as the duty–Brembo calipers pinch beefy rotors–whereas the connection between the seat, pedals and steering wheel has been improved over previous Mustangs. The ten-speed computerized, although, isn’t up for monitor use.
Likewise, the 10-speed computerized transmission does the automotive no favors on monitor. We will see it working effectively on the drag strip, the place it could preserve the engine totally on the cam, however at our official check monitor, the 1.6-mile Florida International Rally & Motorsport Park, the transmission, just like the subpar tires, is extra of a hindrance than a assist.
It merely doesn’t act predictably when pushed on the restrict. A fast downshift may instantly comply with an upshift. Or there might be delay. Or nothing at all.
This made entry into a couple of corners tough, as some braking zones shortly adopted an upshift. After a number of makes an attempt, we discovered the one repeatable solution to enter these corners was to easily trip the rev limiter a bit. In any other case, we ran the extremely possible threat of blowing the entire lap whereas the transmission determined what it was going to do.
It appears like one thing that might be cured with a distinct transmission programming technique that offers extra precedence to the paddles–or at the very least makes the delay predictable. Both means, we needed to abandon a number of laps as a consequence of shifting weirdness.
The brakes positively impress, and Ford has accomplished job speccing the pad compound as effectively. The pads got here in with only a bit of warmth and retained good chunk and constant really feel by our check classes. Hauling down 2 tons from greater than 110 mph requires turning numerous kinetic vitality into warmth, and the large Darkish Horse brakes can simply deal with that vitality switch.
Information Dive
1. There’s no substitute for thrust because the 500-horsepower Mustang Darkish Horse merely dusts our 300-horsepower BMW 435i in each acceleration zone. Vroom! 2. However the BMW makes use of its superior grip to spank the Mustang in each nook, finally gaining such a bonus that it outpaces the Darkish Horse by greater than a full second per lap. 3. Nonetheless, the Darkish Horse reveals good chassis management, significantly beneath braking. These huge Brembos provoke shortly and gradual the automotive with authority. With extra grip and the out there six-speed handbook, the Darkish Horse ought to turn into a lapping stallion.
Our 1:19.90 lap time within the Darkish Horse places it towards the again of the pack of premium sports activities vehicles, giving up seconds or extra to market rivals just like the Supra (1:17.85), BMW M2 (1:16.69) and Corvette Z51 (1:16.16).
The information merely reveals that the Darkish Horse misplaced numerous time as a consequence of its subpar dealing with. Whereas it’s straightforward to say there’s no substitute for horsepower, a comparability with our 300-horsepower BMW 435i mission automotive illustrates the significance of grip: Our VBox information reveals the Mustang successful each single drag race between the corners, with the BMW consistently snatching again that point–after which some.

The lower-powered BMW makes sufficient positive factors in a number of corners that the Mustang can by no means overcome the deficit, even with some extra 200 horsepower on faucet. Ultimately, the Darkish Horse’s greatest lap of 1:19.90 is simply no match for the BMW’s 1:18.81.
The remainder of the Mustang’s graph seems about like we’d count on: Sturdy acceleration off corners, assured brake initiation courtesy of these huge Brembos–though the shortage of grip reveals up in some ABS intervention jitter at occasions–and regular cornering, albeit at lower-than-ideal limits because of the grip deficiency.
Due to comparatively slender tires–simply 235mm fronts and 275mm rears–the 4000-pound Darkish Horse begs for grip. The S650 silhouette, nevertheless, is growing older effectively and retains basic Mustang influences.
We really feel that sticky tires and the out there six-speed Tremec would simply put the Darkish Horse into the low-1:17 second vary. That may put it forward of the Supra and probably even problem the M2. The remainder of the automotive is simply that good.
Grip is an excellent factor, and this final Mustang deserves it. The Darkish Horse’s Dealing with Package deal is definitely worth the improve over the actually mediocre various. So, both test that field on the Ford seller or have Tire Rack on pace dial as quickly as your Darkish Horse hits your driveway.

Nonetheless determining how all of this GRM+ content material works. Will this text be in a hard-copy of the journal? If that’s the case, I look ahead to the nice write-up and shiny photos!
It is unusual to me that the Ford publicists would give journalists a gelded model of their strongest horse. WTH are they considering?

Oh! Neat! I am going to determine that out tonight once I get dwelling. I did not understand the print subscription granted me entry to GRM+ articles. I am excited to learn this one!

I as soon as introduced a turbo Miata to (main automotive journal). They gave it to a journo who I do not suppose had ever pushed a stick earlier than.
Most journalists are by no means going to do a monitor check. They will drive the automotive on Angeles Crest or perhaps in Spain if Ford flies them there. So placing the automotive on 180 TW tires with what are undoubtedly stiffer suspension settings will result in complaints about poor trip high quality and tire noise.
Ford by no means learns. See Shelby GT350 and Efficiency Pack, Boss 302 and Monitor Pack, and so on, and so on

Tom touched on it earlier than in this column, however usually we’re on the mercy of what is within the pool of check vehicles:
How can we choose which vehicles? Properly, we’ll make particular requests when new vehicles are introduced (suppose GR Corolla or new Mustang), however usually we take what we’re supplied. The vehicles are specced and loans are deliberate strategically by the fleet managers, in partnership with the producers’ PR employees.
We’re native to the Miami metro space, for instance, which implies most of our check vehicles are luxury-oriented and totally loaded. A fleet within the Northeast would have loads of AWD vehicles with heated seats, whereas a fleet in SoCal would have each taste of off-road-oriented particular truck to play with. Typically, we study the make and mannequin of a mortgage a couple of days earlier than it’s delivered. And after a tour of responsibility (often the present mannequin 12 months), press vehicles are usually offered to the seller community as run-of-the-mill used vehicles.
I used to be really simply studying that column about the way you get press vehicles shortly earlier than I learn the darkish horse overview.
I suppose the factor that I could not fairly decipher from the story was: does it simply want wider/stickier rubber to be nice? Or did it appear to be one thing extra elementary?
It is lower than a second sooner than a Civic Kind R. Which perhaps says extra concerning the Kind R than the Mustang….
You are higher off shopping for your individual wheels and tire than the dealing with bundle in any case. Should you ought to need the HP inventory wheels for some motive you often can discover them fairly low cost. So until you are planning on working some class the place having the stuff inventory on the automotive issues….
