Audi shows S3 Sportback (2013) – but is a used S3 a better buy?

Here’s Audi’s S3 Sportback, the five-door version of the 296bhp Quattro hot hatch unveiled last year. The S3 Sportback takes 5sec flat to accelerate from 0 to 62mph, that’s one-tenth of a second quicker than Audi’s official figure for its three-door stablemate. That’s because the initial 5.1sec S3 time was only an estimate, and Audi’s subsequent tests have shown the three-door S3 actually dipping below five seconds in the 0-62mph sprint.

Vintech P550 Tribute – Porsche 550 reborn (2012)

Camaro, Sonic fill the Chevrolet stand at SEMA

Custom Camaro and Sonic models lead the way at the Chevroletstand at SEMA this year, with a green electroluminescent Hot Wheels Camaro leading the pack.

The idea was to get the same metallic finish that shined on the first 1:64 scale Hot Wheels Camaro, one of the original 16 die-casts that debuted from Mattel in 1968.
