It's possible to go too small. There's an optimal engine size/output for a given use case. Downsizing works because generally engines are above that optimal size.

Either they're above that optimal size, or below. No wonder sometimes a small naturally-aspirated engine may have an awful fuel consumption, while the very same engine in a turbocharged trim will be better suited.
