The Cadillac DPi-V.R has won both the 24 Hours of Daytona and 12 Hours of Sebring with Wayne Taylor Racing so far this year, so it comes as little surprise that IMSA officials have slowed the Prototype with Balance of Performance changes ahead of the Long Beach Grand Prix.
Wayne Taylor Racing and Action Express Racing’s Cadillac DPi-V.R racecars will use taller first and second gear ratios at Long Beach – a change that is intended to counteract the high amounts of torque the 6.2-liter V8 engine produces low in the rev range. The cars have also received a smaller fuel tank (now measuring 66L in capacity instead of 68L) and a 0.5mm smaller refuelling restrictor.
The Cadillacs will not only be slower at Long Beach – some of the competition will be faster. The Mazda RT-24P and Nissan-Onroak DPi entries have received a turbo boost increase, which should help speed up both cars when accelerating out of the corners. The Tequila Patron ESM Nissan Prototype has received 2 liters less fuel capacity (to 78L) and the Riley-Multimatic LMP2 has received a 2.0mm smaller refuelling restrictor.
The 2017 Bubba Burger Grand Prix from Long Beach will kick off with qualifying on April 7th before the race goes green on April 8th.
