See what Milwaukee uses for road de-icing

There are a few different ways to make icy roads drivable, including spreading sand and salt on them. Here in Detroit, we use tons and tons (and tons) of rock salt on our crumbling roads in part because we're sitting on unbelievably massive salt deposits. Wisconsin is sitting on massive deposits, too -- of cheese brine.

McLaren P1 – the new F1 / P12 arrives

The McLaren P1 – spiritual successor to the legendary McLaren F1 – has been revealed ahead of a public debut at Paris 2012. It’s been a long time coming, but the new McLaren P1 – the name for what we’ve thought of as the McLaren P12 or new F1 – has finally been unveiled. As expected, the new McLaren P1 has more dramatic styling than the MP4-12C with its aerodynamic parts matt black and the flowing contours of the dramatic body painted, with headlights offering a nod to McLaren’s logo and a roof scoop that’s reminiscent of the F1′s.

Porsche shows Cayenne can do off-road – just like the new Range Rover Sport

Porsche shows the new Cayenne S Diesel can do off-road The Porsche Cayenne has come in for some stick since it first arrived a decade ago as the first SUV from Porsche. The world declared the Cayenne too ugly to look at – well, that was the opinion of a certain Mr Clarkson – but anyone who’s lived with a Cayenne will know just how focused it is; it feels like a high-riding M5 to drive and, despite the misconception that sporty SUVs don’t do off-road, it’s remarkably capable when the going gets tough. We’re sure it’s just a coincidence that the 2013 Porsche Performance Drive – from Chisinau to Bratislava – is taking place just after the new Range Rover Sport arrived as a truly capable sporty SUV – with its Land Rover off-road credentials still intact – but the event has given Porsche the chance to show the new Cayenne S Diesel can also do off-road with aplomb.
