McLaren mysteries: Some things you might not know about the P1 and its maker

The McLaren P1 is one of the most spectacular supercars in the world, and it's been an object of fixation for enthusiasts since it debuted as a concept last fall in Paris. The basics are well known: a 903-hp hybrid powertrain, carbon-fiber for almost everything, and taut, curvaceous styling that introduces McLaren to a fresh generation. The P1 grew out of a somewhat hokey mission statement that McLaren produced back in 2009.

BAC Mono: Fancy a Drive?

RS Academy grabs the first two BAC Monos Last month we reported on a new single-seat road car that offers more thrills than a garage full of hypercars for less than the cost of an M5 – the BAC Mono. The brothers Briggs - Briggs Automotive Company – have created the beautifully built, finished and specified Mono as the world’s only single-seat production car (well, the only one that’s actually made it in to production, anyway). Weighing no more than Kylie after a heavy diet, the Mono can scoot to 60mph in just 2.8 seconds before running out of steam somewhere around 170mph.

Jaguar XKR-S (2011) at 2011 Geneva motor show

Jaguar has turned up the power and sharpened the handling on the flagship XKR coupe for the 2011 Geneva motor show. The result: the XKR-S, claimed to be the fastest production Jaguar sports car ever. For 2011, Jaguar is returning the XKR-S to the top of the XK range. CAR readers may recall the well regarded 2008 limited edition that last carried the badge.  The XKR-S has an uprated version of the 5.0-litre supercharged V8 found in the standard XKR. Power moves up to 542bhp (from 510bhp), and torque swells to 501lb ft (up from 461lb ft) thanks to lots of ECU tweakage.
