ROAD­GO­ING VALKYRIE NOT EX­TREME ENOUGH? YOU NEED THE TRACK VER­SION. AS­TON TEASES VALKYRIE AMR PRO

VANTAGE - - Bulletin - WORDS RICHARD MEADEN PHO­TOG­RA­PHY AS­TON MARTIN

WE HAVEN’T EVEN SEEN a fin­ished Valkyrie road car yet, but al­ready As­ton Martin is teas­ing us with ren­der­ings and juicy de­tails of its even more ex­treme, track-only Valkyrie AMR Pro.

To be fair to As­ton, this ultra-ex­treme ver­sion of the Valkyrie was al­ways part of the plan. In­deed, a num­ber of cus­tomers who or­dered a road car also or­dered the track ver­sion. The ul­ti­mate BOGOF deal? Some­how we doubt it.

So what sep­a­rates the AMR Pro from the ‘reg­u­lar’ Valkyrie? As you can see from the ren­der­ings, most of the dif­fer­ences are aero-re­lated. In­deed all the aero­dy­namic sur­faces are said to have changed – most no­tice­ably the much larger front and rear wings – along with what As­ton calls ‘new ac­tive aero control strate­gies’. All in the pur­suit of more down­force.

There are sig­nif­i­cant de­tail changes in other ar­eas of the car. The 6.5-litre V12 will de­velop more power thanks to cal­i­bra­tion changes and re­laxed emis­sion con­trols. The out­put of the Ri­mac hy­brid sys­tem re­mains un­changed, but will de­ploy and re­cover its en­ergy more ag­gres­sively.

Un­usu­ally, the wheels have been down­sized to 18in di­am­e­ter front and rear so that they can run on Miche­lin rac­ing tyres – as de­vel­oped for LMP1 cars in the World En­durance Cham­pi­onship – while the brakes are now car­bon-car­bon, as they are per­fectly suited to cir­cuit use and of­fer max­i­mum per­for­mance.

Fur­ther weight sav­ings will be made – quite some­thing as the road car is al­ready tar­get­ing 1000kg – thanks to the use of a poly­car­bon­ate wind­screen and side win­dows, plus the re­moval of the road car’s heater/de-mis­ter blower and in­fo­tain­ment screens. The ex­haust sys­tem will also be lighter, as will the car­bon­fi­bre body­work. New sus­pen­sion up­rights and car­bon­fi­bre wish­bones are F1-spec, like­wise the moulded driver’s seat.

Un­sur­pris­ingly, the Valkyrie AMR Pro prom­ises mind-bend­ing per­for­mance. Ac­cord­ing to Red Bull’s sim­u­la­tions, it will be ca­pa­ble of giv­ing a con­tem­po­rary F1 or LMP1 car a run for their money. No won­der, with sus­tained cor­ner­ing forces in ex­cess of 3.3g and brak­ing de­cel­er­a­tion of more than 3.5g. Pre­dicted top speed? Ap­proach­ing 250mph.

Whether any of the own­ers will be ca­pa­ble of ex­tract­ing this per­for­mance re­mains to be seen, but they will all be put through an in­ten­sive and com­pre­hen­sive driver devel­op­ment pro­gramme, with ac­cess to the same fa­cil­i­ties as As­ton Martin Red Bull Rac­ing’s F1 driv­ers.

Just 25 of the AMR Pro Valkyries will be built, with de­liv­ery sched­uled for 2020. The price is hard to pin down, as As­ton Martin has said from the on­set that the road car would cost be­tween £2m and £3m. Given the more ex­treme na­ture of the AMR Pro, its rar­ity and likely value in years to come, we’d es­ti­mate a price of £3.5m plus taxes. Need­less to say, don’t bother rum­mag­ing down the back of your sofa for loose change: they’re all sold.

Above and below Ren­der­ings show Lmp1-style aero treat­ment, de­signed to gen­er­ate more down­force. Under the skin, 6.5-litre V12 will gen­er­ate even more power than the road ver­sion, which is thought to be tar­get­ing 1000bhp
