4wd vauxhalls ARE coming soon, the new epsilon 2 platform is fully developed now, and is adaptable to both 2wd and 4wd.
The insignia is coming out with 4wd next year, and will be 300bhp or so.

I suspect an astra will follow relatively soon after.

Engines will include the mighty vectra vxr 2.8 v6 turbo, and it will come with an LSD option too.

Vauxhall arent dicking around these days, shame ford wont take the lead, they have most of the technology they need in the volvo range!
