Yes - more power, more downforce, more track pace to make a more track/race-focussed car. Just like the McLaren F1 GTR. And the McLaren P1 GTR. That's why a Speedtail GTR doesn't make any sense. Sure, more power is doable (it's always doable), but downforce and track pace are the antithesis of the Speedtail's purpose - it's not a track car. Except maybe a drag strip. Plus with a big fat wing on the back it would look like the Nissan R390.
