Who has never been afraid to receive a pound of lead see a rocket on the highway? Faced with such a request, Jaguar is neither one nor two, and fly to the rescue of potential targets that we are with the XJ Sentinel.

One of the brands featured at the Concours d’Elegance at Pebble Beach this year will be Jaguar , whose models are honored to be unveiled. The festivities of the 75th anniversary continuous!

Um, we’re sure there’s something sensible to be said about this Porsche concept, but we’re not altogether capable of coherent expression at present. We want to own one of these so badly, we don’t even care if it has an engine. And boy does the 918 Spyder have an engine. A 3.4-liter V8 petrol burner is combined with electric motors to put out 500bhp, while featuring the mind-altering acceleration to go from a standing start to 62mph in just 3.2 seconds.

What is it?

The XKR 75 may be saddled with a somewhat ham-fisted name – one that reflects how many such cars Jaguar will produce over the next year or so – but it’s also the fastest production Jaguar in history, assuming you don’t count the largely hand-assembled XJ220 of yesteryear. In many ways, it’s the car Jaguar has always wanted to build but has never quite had the courage to do so. Having said that, on paper the 75 doesn’t appear to be that much more thrusting than the regular XKR, despite costing a full £10k more than the regular model at £85,500. The key mechanical differences involve the engine, suspension and exhaust. Officially the 75 has another 20bhp and 26lb ft more than the XKR on which it is based. The suspension is also lower and stiffer while the exhaust has been replaced with a sports item that is both louder and more free-flowing – all of which sounds fairly predictable on the surface, and perhaps not entirely deserving of another 10 grand. What’s it like? In reality, the 75 feels like an entirely different animal compared with the regular XKR.
