Ah, I knew that story was going to come up eventually... I may take the Saleen for a spin later, but for now I decided to focus on the shiny, new toy.
The Group C era has, perhaps more than any other era of motorsport, given us some sad stories of heartbreak, wasted potential and "what could have beens". The poster-child for this is probably the Lancia LC2: developed and raced "on the cheap", the Martini-liveried prototypes were often faster in qualifying than the much more pedestrian-looking Porsches, but their poor reliability constantly forced them on the sidelines. But even more soul-crushing is the fate of Aston Martin's ambitious foray in the prototype racing scene, in the late 80s. After providing engines for the the Nimrod and EMKA cars earlier in the decade, the company, which back then was a small outfit very much stuck in its old ways, decided to take up the ambitious challenge of developing an all-new car to compete against the Porsches, Jaguars and Sauber-Mercedeses of the time. In reality, however, the prototype would be an Aston Martin in name only: the cutting-edge carbon-kevlar monocoque and the skin draped around it would be designed by the joint team of Ray Mallock and Max Boxstrom, of Ecurie Ecosse fame, and built by composite specialist Courtaulds. The engine, which was to be shared with the brand-new Virage road-going GT car, was originally intended to be developed by Cosworth, but the high demands of the British firm led Aston Martin to look elsewhere, and namely, on the other side of the Atlantic: Callaway Cars was choosen to develop the 5.3 litre Tickford V8 of the aging Vantage. While the firm is nowadays mostly remembered for its twin-turbo Corvettes, it had some credentials as a racing engine developer, having built an Indy-spec eight-cylinder engine almost from scratch in just 11 months; and they diligently set to work on new 32-valve, DOHC cylinder heads. In the bulky Virage, the seemingly endless amounts of torque available produced supercar levels of acceleration; and in racing trim, stroked to 6 and later 6.3 litres, the
RDP87 produced up to 720 hp - a figure that was, and still is, quite respectable.
The canted - and, as we will soon find out, quite cantankerous - V8.
The car was christened AMR1, and signed up for the 1989 World Sportscar Championship with very high hopes of bringing the Aston Martin name back to the top echelons of motorsports. During its maiden season, however, the car would show all sorts of teething problems. It didn't even take part to the first race of the season, in Suzuka: the only chassis built at that point,
AMR1/01, was crashed during tests at Donington, and could not be repaired in time. In its first outing, at Dijon-Prenois, the car finished in a disappointing 17th position, eight laps down the winning Porsche, and two behind the Chamberlain-Spice that won in the C2 class. At 600 horsepower, the car was significantly underpowered against its turbocharged competition; the aerodynamic package, on the other hand, was a bit
too good at generating downforce, giving the car an alarming tendency to porpoise. At Le Mans Ecurie Ecosse would enter two cars, with one retiring with electrical problems, and the other finishing the grueling race in 11th, more than 20 places up from its starting position. Afterwards, the adoption of a larger and more powerful engine and some adjustments to the suspension and aerodynamics setup allowed the AMR1 to improve on its competitiveness: at Brands Hatch, in front of a British crowd, the only car entered would be "best of the rest", arriving in 4th behind the dominating Saubers, and at the end of the WSC season Aston Martin would manage to finish 6th in the Teams standings, leaving behind the more established Toyota team. Had things gone to plan, 1990 would have seen the cars converted to the improved AMR2 spec, featuring some much-needed aerodynamic improvements and an even more capable version of the Callaway powerplant, rumored to produce something north of 740 hp; eventually, this too would have been replaced by a far more advanced AMR3, which the Mallock-Boxstrom team had already begun to engineer.
The AMR1 didn't bring home gobsmacking results, but 1989 was still a promising rookie season for the Aston Martin-Ecurie Ecosse team-up.
But in 1990, Ford - which up until then had been a minority shareholder of the British carmaker - acquired Victor Gauntlett's share of the company. Meanwhile, a rule change was announced for the 1991 season, which would limited Category 1 Sportscars to the use of 3.5 litre, naturally-aspirated engines. Ford, which also owned Jaguar, had no use for two teams racing in the WSC, and a limited supply of Cosworth F1 engines to go around. Coventry's program was much more established, having dominated the previous two seasons with a car, the XJR-8/9, that wasn't too different from the AMR1, but had a much longer gestation. And so, the daring and ambitious Aston Martin racing program was unceremoniously terminated before the AMR1 could mature into a title contender. Fortunately, Aston Martin would return to Le Mans, both in the GT classes, where it would become of the dominant forces of the past decade, and in the top-billed LMP1 category, following up on a mildly successful Lola-designed, V12 car with the AMR-One, one of the worst flops in the history of the division.
Underwhelming as it may have been, the AMR1 wasn't sold as spare parts to other teams.
In its Forza Motorsport incarnation, the AMR1 features the ultimate, Version III evolution of the
RDP87, displacing 6.3 litres and pushing 740 hp and a
gargantuan 841 Nm of torque to the crank: that gives the Aston an advantage of over 20 Nm over the Sauber C9 and Jaguar XJR-9 of the same era. And contrarely to the Merc, which is turbocharged, and the Jag, which has an engine that is more fractioned, over 80% of that torque is available from the word "go": this makes for a sometimes frightening experience, with the ultra-wide rear tires struggling to cope with the stress induced by the mighty Callaway powerplant in 1st and 2nd gear. But taming the boisterous V8 only requires some exercise; and after getting the hang of its throttle response, the car really came alive in the fast sweepers of the Circuit of the Americas, thanks to its precise steering, seemingly infinite amounts of lateral grip, and powerful brakes. It's such a shame, then, that a 1990-spec AMR2 never became a thing: it's easy to imagine that with some work by its two highly competent chief engineers, and perhaps with some injection of cash from Ford, it would have been a sweeter thing still.
All that is left now is a Lancia LC2, and then we can really have a Group C1 party!
Pros: it looks cutting-edge even today, imagine in 1989!
Cons: yes, Callaway, there
is a thing such as "too much torque"...
