Over the weekend, Porsche released the first details of the thoroughly revised 919 Hybrid, which is due to race in this year's FIA World Endurance Championship. While the hybrid drivetrain of last year's car is carried over, the new-for-2015 Porsche 919 boasts a completely new aerodynamics package.
Ahead of the car's Monte Carlo Rally debut next week, Volkswagen revealed the second generation Polo R WRC. This is the second generation of the two-time World Rally Championship winning machine, which builds on the existing machine but features an updated drivetrain and a revised exterior. Retained to drive the Polo R WRC are Sebastien Ogier, Jari-Matti Latvala and Andreas Mikkelsen.
McLaren, meanwhile, have published addition images of the upcoming P1 GTR. Based on the sophisticated road-going supercar, this is a trackday only machine and will be powered by a hybrid drivetrain capable of more than 1000 bhp at full pelt. The P1 GTR will be launched at the Geneva Motor Show early in March.
Rounding up our coverage from the Scottsdale auctions, we have added the results for the sales from RM Auctions, Bonhams and Gooding. The weekend was topped by RM Auctions, who sold this Ferrari 250 LM for just over $9.6 million.
