Settling in behind the wheel of the Aston Martin Valhalla feels a bit such as you’re on the point of race a Le Mans hypercar.
You sit inboard, nestled up in opposition to a slender centre console, snugged in hip-hugging seats that place your bottom 25mm decrease to the bottom than in every other mid-engine supercar. The firewall separating you from the interior combustion engine is true at your shoulder blades.
Instantly forward of you, behind the trapezoidal steering wheel, is an easy display with a configurable sprint show. The windscreen bulges ahead, supported by contorted A-pillars.
Bodywork looms over wheels positioned simply forward of your toes, and the view of the tarmac forward begins proper on the base of the windscreen.
Look across the cockpit and the race-face vibe fades just a bit.
There’s switchgear an identical to that of standard Aston Martins on the steering wheel and centre console, speaker grilles and vents that betray the presence of audio and air con methods, and luxurious touches similar to energy attain and rake adjustment for the steering wheel.
It would look a bit like Aston Martin’s mega-dollar Valkyrie, a barely useable Le Mans racer for the street created by legendary F1 designer Adrian Newey and powered by a mid-mounted V12 that’s so loud you should put on ear safety if you drive it, however the Valhalla is supposed to be a supercar you may drive daily. It’s Aston’s first correct manufacturing mid-engine sports activities automobile.
The Valhalla is underpinned by a bespoke light-weight carbon-fibre monocoque chassis, with aluminium subframes finding the multilink rear axle and an F1-style pushrod entrance suspension.
It has a plug-in hybrid powertrain that includes a 609kW, flat-plane crank model of Mercedes-AMG’s versatile 4.0-litre bi-turbo V8, and three electrical motors that between them produce an extra 185kW.
Two of the e-motors, compact radial flux models designed particularly for the Valhalla, are positioned on the entrance axle to drive the entrance wheels and are housed inside a custom-built electrical drive unit that enables cross-axle torque vectoring. The third e-motor is built-in with the brand new eight-speed dual-clutch transmission.
The three e-motors are powered by a sophisticated high-performance battery that mixes combines the power to quickly deploy its state of cost with quick vitality absorption and high-power density. The battery is cooled by an electrically non-conductive fluid to make sure every of its 560 particular person cells are saved at their optimum temperature.
Complete system output of the Valhalla’s powertrain is 794kW and 1100Nm. That’s sufficient grunt to ship a claimed 0-100km/h acceleration time of two.5 seconds, and a high pace of 350km/h from a automobile weighing about 1720kg.
The Valhalla is fitted with an lively aero system developed with assist from engineers on the Aston Martin Aramco F1 Group. The system can range the angle of assault for the entrance and rear wings to assist keep aerodynamic stability throughout a broad efficiency envelope.
The aero {hardware} and software program assist the Valhalla develop greater than 600kg of downforce between 240km/h and 350km/h.
The by-wire braking system combines large Brembo carbon-ceramic rotors – 410mm on the entrance and 390mm on the rear – the biggest ever fitted to an Aston Martin, with regenerative braking from the entrance e-motors.
All are modulated by the Valhalla’s built-in automobile dynamics management system. The e-motor within the transmission recoups vitality and sends it to the battery when the driving force lifts off the throttle.
Normal wheels are solid aluminium alloys, 20-inch up entrance and 21-inch on the rear, wrapped in 285/30 and 335/35 Michelin Pilot Sport 5S tires respectively. The bigger rear tires funneling the lion’s share of the PHEV powertrain’s torque to the tarmac with the assistance of an e-diff.
On start-up, the Valhalla selects Sport because the default drive mode. Three different modes, Pure EV, Sport+ and Race, could be chosen through the rotary controller on the flying buttress centre console.
Every has its personal mixture of settings for the powertrain, together with entrance axle torque vectoring and hybrid system integration, plus completely different suspension stiffness, lively aero, and steering calibrations.
In Pure EV mode, the Valhalla is pushed solely by the entrance e-motors and can journey as much as 14km at speeds as much as 140km/h earlier than the interior combustion engine fires up.
For our check drive at Aston Martin’s compact Stowe circuit at Silverstone, manufacturing facility race driver Darren Turner advisable the Sport+ drive mode, with the transmission set to handbook shifting.
He additionally steered we change the soundness management off, and set the traction management to 5, its mid-way setting (as within the ‘entry-level’ Vantage sports activities automobile, one means essentially the most intervention and 9, none).
Darren reckoned this setup would enable us to benefit from the Valhalla’s prodigious energy and torque on the tight and twisty monitor. And he was proper.
It is likely to be a mid-engine supercar with nearly 800kW on faucet, however the Valhalla immediately felt as benign and playful as Aston’s entry stage Vantage coupe. By the second lap we had been drifting it out of the tight corners with full confidence.
Although it doesn’t rev as laborious as different trendy flat-plane crank V8s, its peak energy and torque arriving at a comparatively modest 6700rpm, the snarly Mercedes-AMG engine is epic.
What’s extra, the instant-on torque from the e-motors makes the Valhalla really feel punchier and extra responsive any of the non-hybrid Aston V8s, a sensation amplified by the fast shifts from the dual-clutch transmission.
There’s lots happening below the pores and skin of the Valhalla, however you’re by no means conscious of it. There is likely to be a pair of e-motors on the entrance axle immediately various the torque to assist with flip in response and nook exit, however you by no means really feel them.
The steering is direct and communicative, telegraphing camber and floor adjustments and slip angles as clearly as if the Aston was a light-weight rear-drive automobile.
It’s ultra-high tech, the Valhalla, nevertheless it feels remarkably analogue from behind the wheel. And such is the coherence of the chassis and powertrain, you may shortly discover stability and tempo on this quick and highly effective mid-engine Aston.
The one time we may really feel the entrance axle’s e-motors at work is after we switched between the Sport+ and Race modes.
Completely different mapping means Sport+ mode delivers extra hybrid intervention, and the automobile pulled a contact extra strongly out of Stowe’s tight corners. However the interplay between the interior combustion engine and the e-motors was completely seamless.
Aerodynamics is the one space the place there’s a clear hyperlink between the Valkyrie and the Valhalla. “We took the lively aero learnings from the Valkyrie and fine-tuned them,” confirmed Aston Martin automobile efficiency director, Simon Newton.
“However the activity was a bit extra advanced with Valhalla as a result of now we have much more drivetrain choices to stability.”
The Stowe circuit isn’t large enough to evaluate the effectiveness of the lively aerodynamics of the Valhalla, although in Race mode we may watch the lively rear wing shifting its angle of assault between the excessive downforce and drag discount settings and snapping to consideration to behave as an air brake below heavy braking.
What’s most spectacular concerning the Valhalla is that regardless of a powertrain format and applied sciences which can be unfamiliar territory for Aston Martin, it appears like an Aston Martin. It has the identical mixture of efficiency and approachability that makes the present Aston Martin lineup so interesting to drive. It’s quick however not threatening as you strategy its limits.
That’s excellent news for a coming technology of Aston Martins that, just like the Valhalla, will all have 745kW or extra plug-in hybrid powertrains, and electrically pushed entrance axles.
“We’re on a journey with hybrids,” confirms Mr Newton, “it’s thrilling what we’ve discovered from the Valhalla venture; how you can leverage the methods to essentially amplify the standard Aston driving expertise and take it to the following stage.”
