Yeah as Budnicks stated, essentially nothing really beat the Cobras during it's reign.
Not that I could remember
But they were a "handful" to drive.
And yes allegedly the Mongoose or Mangusta is the Cobras' natural enemy in the animal kingdom.
A clever name for a car.
I "think" that was the beginning of their so called demise, if they truly had one per say.
-Competition developed at a hungry pace which led race-car design towards a more "stable" platform, another words, better handling characteristics etc.
The detomasso Mangustas arrived on scene around 1969/1970 and were not competitive on the "GT" scene.
The AC Cobra was not being raced competitively on the World Scene at that time, her time was done. (nothing more than a Frankenstein monster on the race course)
Ford came out with the Daytona coupes then the GT40s
Chevrolet perfected the independent suspension Corvette cars
Ferrari and Porsche were "strong"
Ford really had no more to do with the Daytona Coupe than the 289's, which were seriously warmed over by Shelby Ameican. Pete Brock designed the Coupe body by gut. Also, the front end of the Coupe was sprung on a single group of transvers leaves, unlike the AC roadsters. Pete Brock said of the Coupe that it was like roadracing a pick up truck for 24 hours. They had a scant 5 mph advantage over the Ferrari 250 GTO. Shelby/Brock beat the Ferrari in 64. During this time Ford was trying to buy Ferrari, but Enzo refused to consider Ford as player in the sale of His company & marque.(Fiat ended up with Ferrari) Upon Enzo's refusal to sell to Ford, Henry told Shelby to 'shelve' the Coupe & work in house with them to develop Eric Broadley's Lola GT into the new Ford GT class racer to go & kick Fertaris *** in Hs own sandbox.
As for the Goose, the project was conceived between Shelby & deTomaso & the theme was to build a 'Poor Man's' GT-40 & they developed the car from an already existing design by Giorgetto Guigiaro. Shelby supplied the 302's(American export) & the 289's(Euro). The prototype debuted @ the 1966 Turin auto show, on the heels of the GT-40's 1-2-3 overall victory @ LeMans.
However, Shelby backed out of the deal(though He advertised the car in America & took a role as a distributor, & campaigned a couple cars)giving it bad press. deTomaso was on a shoestring, losing Shelby's money denting Him seriously & could not afford a proper R & D program, & He literally started building 'prototypes', making small changes throughout production(1967-1971)....the speculations throughout the years as to the ill handling turned out to be total horseshit(like i knew they eventually would be). In 2010, Dick Ruzzin, a GM designer Who bought the 68 Goose built for Bill Mitchell(owned to this day & clocked 70,000 miles)that had a special Zora Corvette motor installed @ the factory(the then new 350 4 bolt block with 327 internals) discovered & rectified what caused 90% of the *** end's misbehaving. Had the car been properly R&D'd, this problem would have been sorted out as it's simple in nature. It came down to the method of hanging the transaxle......the ZF was hard mounted to the hanger/bridge. The bridge was 'SOFT' mounted @ the driveline's subframe rails. The car did have chassis flex under cornering pressure....the soft bush mounts exaggerated the problem & after some homework, Dick discovered that from rear spindles, tip to tip, there was an inch & a half of movement under hard cornering pressure, which led to rear camber fluctuation problems. Dick reversed the mounts, bush mounting bridge to ZF transaxle & hard mounting bridge to frame rails......easy peasey & shooed the spooks out of the ***. There are kits to stiffen chassis now to quell the flex. There are a handful of race Mangustas today that campaign in vintage races with good success. One of them is in Studio City Ski.
What's nutz is when the proto debuted in Turin, the car was already called Mangusta,,, before Shelby pulled His financial power to back it. Coupled with he fact that He acted as sales rep for American exports, well after He did pull His finance from project.
The moral here is that with the fixes, the car TRULY IS a Cobra killer.
