Bentley on Friday launched extra technical particulars on the renewable-fuel Continental GT3 race automotive it plans to run on the 2021 Pikes Peak hill climb, scheduled for June 27.

The British automaker is hoping for a 3rd Pikes Peak class report, this time within the Time Assault 1 class. Bentley took the report for manufacturing SUVs with the Bentayga in 2018, and the production-car report with the Continental GT in 2019.

As a result of it is competing within the Time Assault 1 class this yr, Bentley was allowed to enter a modified automobile. Particularly, a modified model of a automotive raced within the in style GT3 class earlier than Bentley’s exit on the finish of 2020.

The GT3 racer is powered by the identical twin-turbo 4.0-liter V-8 used within the Continental GT highway automotive, however tuned to supply 750 hp and 737 lb-ft of torque at sea degree. Whereas the thinner air at altitude (the Pikes Peak beginning line is at 9,300 ft above sea degree) robs engines of energy, Bentley claims the engine could have a better output for the race.

Modifications embody extra increase stress (greater than 31.9 psi, Bentley stated), new connecting rods, pistons, and a carbon-fiber consumption manifold to deal with that additional stress, plus customized Inconel exhaust manifolds from Akrapovič.

The engine runs on what Bentley calls 98RON renewable racing gas. Bentley did not present a lot element, solely saying that the gas is a “mix of superior biofuels,” and calling it a “technological stepping stone” to industrial renewable fuels with as much as 85% fewer greenhouse-gas emissions.

Modifications to the remainder of the automotive embody an upgraded cooling system, water-cooled brakes, and Pikes Peak-specific suspension settings, together with lowered camber and the softest-possible springs and anti-roll bars, permitting extra weight switch beneath braking, Bentley stated. The gearbox is identical unit utilized in the usual GT3, with a particular lubricant from Mobil 1.

Skinny air means aerodynamic components do not generate as a lot downforce as they’d at sea degree. To compensate for that, Bentley put in the biggest rear wing it is ever fitted to a automotive, plus a two-plane entrance splitter and separate dive planes on the entrance for steadiness. At sea degree, these components generate 30% extra downforce than the usual GT3, Bentley stated.

Growth was break up between the U.S. and the U.Okay. Bentley performed chassis-development testing at California’s Willow Springs racetrack, and high-altitude testing in Aspen, Colorado, with dyno testing of an engine operating the 98RON gas within the U.Okay.

To drive the Continental GT3, Bentley tapped three-time Pikes Peak champion Rhys Millen. He earned Bentley’s two earlier Pikes Peak data, however can he make it three for 3? We’ll discover out quickly.
