The British company is putting rivals like Porsche and Lamborghini on notice.

McLaren's street car-building division doesn't have the heritage of much older sport car brands like Porsche and Lamborghini. The company doesn't see that as an issue, however.In a move sure to draw the ire of its rivals, a spokesperson for the company told Australian publication CarAdvice it strongly believes it builds better cars than anyone else on the market.

"At McLaren, we like to think we've got the only authentic sports car setup in the market," said Paul Burnham, the chief engineer for the brand's Sports Series line.

To prove his point, he explained there's not a lot that separates the different members of the company's lineup. They all feature a carbon fiber tub, hydraulic power steering instead of an electric setup, and a twin-turbocharged 3.8-liter V8 engine mounted right behind the passenger compartment.

"It's one of the reasons why the 570S gets slimmer tyres than the new 720S Super Series car, otherwise there isn't a lot that separates these two cars, as far as grip levels go," he added.

We'd be surprised if Porsche, Lamborghini, Ferrari, and the rest of the world's supercar manufacturers issue an official statement in response to McLaren's comments. However, an executive from a rival automaker might decided to speak his or her mind during one of the countless interviews that will come out of the upcoming Frankfurt Auto Show.
