At the Los Angeles Auto Show, our eye was particularly caught by a couple of new racing cars brought by Mazda and Porsche. The most striking of the pair is undoubtedly the Mazda RT24-P. Built to IMSA's new DPi regulations, it is based on a chassis developed by Riley and Multimatic and is powered by an evolution of Mazda's two-litre turbocharged engine. As part of the DPi regulations, Mazda was allowed to provide a bespoke exterior design, which the Japanese company did with great verve. The Mazda RT24-P, like the other DPi machinery, are expected to be considerably faster than the outgoing LMP2 and Daytona Prototype cars.
Porsche also broke new ground with the all-new 911 RSR. While it retains the familiar profile of the 911 road car, it is actually mid-engined. This allows for a better weight distribution and frees up space for a much larger rear diffuser. The new-for-2017 911 RSR will race on both sides of the Atlantic.
Also breaking cover at LA was the Alfa Romeo Stelvio, which is the Italian manufacturer's first SUV. It was displayed in the range-topping, 505hp Quadrifoglio guise.
McLaren Special Operations, meanwhile, used this opportunity to announce the development of a new three-seater supercar. It is code-named the BP23, and like the McLaren F1 it was inspired by, production will be limited to 106 examples. Although the first BP23 is not due to be delivered until 2019, all 106 available cars are already spoken for.
For the upcoming Dakar Rally, MINI will field the newly developed John Cooper Works Rally. Like its predecessors, it is powered by a very potent twin-turbocharged, straight six diesel engine.
