Day 2 at the International CES

If you have never seen a 110-inch, ultra-high-definition TV screen, where every molecule of digital delirium dances across the screen in pulses of pixelated promiscuity, well, you're really missing out.

For our part, we sat transfixed before it more like the monkeys in 2001: A Space Odyssey.

Mini John Cooper Works WRC: the roll cage in detail

Mini claims it’s created the safest WRC car ever – with a little help from Prodrive.  And to prove the point, they’ve opened up the Mini Countryman WRC’s innards and spilled some of the secrets of its rollcage.

Vauxhall Ampera: Try for 30 days – and then give it back

It’s a clever scheme, because the Ampera is a good car.
