We've seen beaucoup 1 Hatches over the last 3 years throughout Europe - including on the roads and in special exhibits in places as diverse as little Malta and the Canary Islands. I wouldn't describe the hatch's backseat as significantly inferior to the coupe's. And if a 1 Series hatchback 123d was available in North America, I would find that very appealing.
