Glickenhaus SCG 004C gets its first track shakedown in Italy

It can be hard to keep track of the various Scuderia Cameron Glickenhaus vehicles on the way because we read about them for years before seeing them. No matter, when they do show, they are welcome sights. The SCG 004C, hardcore racer that’s successor to the Nürburgring pole-sitting 003C, is the next to make the transition from text coverage to track footage. Developed to ultimately serve as a platform for GTE, GTLM, GT3, and GT4 categories as well as Germany’s NLS series, SCG put the first example to test on Italy’s Cremona Circuit. Years ago, SCG’s plan was to have Nissan’s 3.8-liter twin turbo VR38DETT V6 from GT-R placed amidships. That plan morphed into using a 6.2-liter naturally-aspirated pushrod V8 based on GM’s LT4 block, developed by Autotechnica Motori.

Fellow Italian company Podium Advanced Technologies is helping with overall vehicle engineering, SCG saying the 004 chassis — which will get an 004S road version, 004CS road/track version, and the 004C track-specific car — has already been through 35,000 hours of development work. As to the engine, James Glickenhaus told Sportscar365, “It can’t rev very high, but GT3 engines can’t rev very high anyway with the restrictors. You get a very low center of gravity and it’s a very compact engine, so there’s a tremendous amount of space around it to blow air around and keep it cool.” The 003C used a 3.5-liter, twin-turbocharged Honda HR35TT V6 built for IMSA’s Daytona Prototype category. Glickenhaus said the change in philosophy with the 004C meant that “with the low-end torque, we’re going to be able to be faster coming out of the turns than we were with the 003C.”

On the first shakedown and improvements compared to the 003C, the owner explained that two more inches of suspension travel in the 004C would translate into softer landings on the high-flying Nordschleife, and the new nose results in improved downforce and better aero balance. The 004C is also about 220 pounds lighter than its 2,976-pound forebear.

The 004C will of course be restricted to series power limits. Since the road-going cars won’t be limited, customers will get about 680 hp out of the V8 in the 004S, and around 850 hp out of the 004CS with the help of a supercharger bolted to that V8. Estimated price for the hand-built, carbon-fiber bodied 004S is $485,000, the 004CS will start around $650,000. As with the racer, all versions will employ a three-seater cockpit with a central driver’s seat, the choice of a six-speed manual or seven-speed dual-clutch transmission; the race car fits an Xtrac sequential transmission.

After its first test at Cremona, the 004C heads to Aragon, Spain, for a 30-hour endurance test. Its first race comes next month in the Experimental Class in the NLS series, before racing again in April, and a tilt at the Nürburgring 24 in May.

Lamborghini Squadra Corsa previews 830-hp hypercar and racing Urus ST-X

At the conclusion of last year’s Lamborghini Super Trofeo series, the Sant’Agata Bolognese carmaker’s Squadra Corse division unveiled the SC18 Alstom. That was a one-off, customer-commissioned, extreme track car based on the Aventador SVJ, and the first wholesale creation from the racing department. At this year’s series finale in Jerez, Spain, it teased a limited-run hypercar and an evolution of the race-bound Urus ST-X. The hypercar proves a rumor from earlier this month, when a poster at the McLaren Life forum said he was “Going to spec next week and test drive the SVR V12 track version of AV,” that AV standing for Aventador. Lamborghini says the track-only car, designed by the company’s Centro Stile department, will debut next year.

The rumor had posited the hypercar as a ne plus ultra expression of the Aventador’s 6.5-liter V12, and that seems to be the case. Engineers extracted 830 horsepower from the naturally aspirated engine, 70 hp more than found in the SVJ. In place of the road car’s seven-speed, single-clutch ISR transmission, the unnamed hypercar uses a six-speed Xtrac sequential gearbox, and a mechanical limited-slip differential can be adjusted by the driver for preload. The standard Aventador chassis has been reworked around that powertrain for aerodynamic and safety reasons. The front structure’s made of aluminum, a more pliant — and less expensive — material to deal with in case of incidents on the track. The engine’s been wrapped in a steel cage in order to increase torsional and bending stiffness. Airflow improves thanks to dual intakes on the hood, an airscoop over the cockpit, and a stonking rear wing. 

The Urus ST-X has undergone a few changes since its debut last year. The Verde Mantis SUV has been lightened by about 25 percent compared to the production version with “a lighter structure,” a vented carbon fiber hood and rear wing, and a racing exhaust. The cabin’s luxurious appointment are replaced by a roll cage, racing seats, and a fire suppression system. Scheduled to make its race debut at the end of October 2020 in Misano, Italy, the first pilots to get a chance behind the wheel will be winners of the four classes in the Super Trofeo series.
