To minimize latency, you'd want to pick the smallest single that will do the job right.

Single doesn't necessitate 'big', just 'big enough'.

If BMW's goal is no-lag, then they need a single turbo that is as small as possible, while still able to produce 300 hp before efficiency collapses.

What they end up choosing will dictate how much more top end you can get out of that setup.

It could be a little more efficient if it's 'just big enough'... or a lot better if it's got plenty of headroom.

I'm basically saying that just because it's a single, we shouldn't assume it's some 30R or whatever.
