Recall the AM-RB 003? This concept was unveiled in March 2019 at the Geneva Motor Show, serving as a glimpse into Aston Martin’s forthcoming mid-engined supercar. Initially, the British brand promised the production model would be revealed before the end of 2021. Yet, here we are in the second half of 2024, and the final product is still absent. In the interim, a prototype has been spotted at the Nürburgring. Despite the absence of customer models, this test vehicle is immediately recognizable with its prominent rear wing. This design element appears more polished than its predecessor. The aerodynamic package is capable of generating over 1,322 pounds of downforce at 149 mph. The camouflage suggests Aston Martin is still withholding the final design. The lightweight side windows indicate this could be a hardcore AMR version, as the 2021 press shots of the standard Valhalla featured conventional glass. The subdued engine note is not from an Aston Martin engine. Originally slated to feature a twin-turbo, 3.0-liter V-6, the supercar now employs a larger AMG-sourced V-8, also twin-turbocharged, with a 4.0-liter flat-plane crank that revs up to 7,200 rpm and powers the rear wheels. It is anticipated that the production model will be louder, unless this prototype is intended for the European market with stricter noise regulations. The combustion engine alone delivers a robust 800 horsepower to the rear wheels. However, the Valhalla will not be solely a gasoline-powered supercar; it will incorporate a hybrid powertrain with three electric motors, totaling 998 hp and enabling all-wheel drive without a conventional reverse gear. The front-mounted motors provide the reverse function, allowing for weight reduction. The third electric motor is integrated into the transmission, powering the rear axle and serving as both starter and generator for the combustion engine. Assuming the performance figures remain unchanged since Aston Martin’s last update, the Valhalla will accelerate from 0 to 62 mph in 2.5 seconds and reach a top speed of 217 mph. In electric mode, it will max out at 80 mph and travel up to nine miles. The target weight is an impressively low 3,417 pounds before fluid additions. Aston Martin plans to commence production this year, with 999 units slated for assembly. The Valhalla will compete against the successor to the Ferrari SF90 Stradale, the McLaren Artura, and the newly revealed Lamborghini Temerario. Although the price remains undisclosed, it is expected to be significantly lower than the flagship Valkyrie. Originally, a third mid-engined supercar, inspired by the 2019 Vanquish Vision concept, was planned, but it was canceled last year. However, a new front-engined Vanquish is on the horizon, equipped with a powerful twin-turbo V-12 engine delivering 824 hp and 738 lb-ft of torque.
