Hennessey Cadillac Escalade gets 557 hp

The 2015 Cadillac Escalade is about as American as an SUV can be. We didn't find the 420-hp, 6.2-liter V8 lacking in any way, but if you want something with a little more grunt, Hennessey Performance Engineering and its HPE550 upgrade should help. Hennessey says the HPE550 Escalade package bumps output to 557 hp and 542 lb-ft of torque with the help of a belt-driven supercharger producing 6 psi.

Lotus Elise (2010): a new face for evergreen roadster

By Tim Pollard First Official Pictures 16 February 2010 15:19 Lotus has just whisked the covers off the new, sleeker 2011 model year Elise – with a new fish-eyed face inspired by the Evora and a one-off 2007 'concept toy car' made for model car specialists Hot Wheels.

McLaren P1 (2013) CAR's race-speed Goodwood ride

The McLaren P1 leaves the startline like a shard of shrapnel riding the percussion wave of an explosion. It needs high-definition slow-mo to describe it, like those films of a bullet shattering an apple, or the slow-motion shots of an F1 car skipping over a kerb, front wing flexing, tyres deflecting, all that physics captured in beautiful, drowsy detail. In my mind, when I re-live the first moments of my ride up the Goodwood hillclimb in McLaren’s new hypercar, I see the release of energy in the same 1500-frames-per-second style.
