At what amount of power is an engine not weak? At 300 hp? At 350 hp? At 400 hp?
Who decides that? You?
Whatever you say, is your opinion. Not a statement of facts.
In the 80s , a 150 hp engine was considered powerful enough for sports cars! The Mustang had a 119 hp V8! The most exotic car by then, the Lamborghini Countach, had 370 hp V12 engine. Now, this power 150-200 hp, is considered appropriate only for small and cheap vehicles. 450 hp is enough for a big, flagship , luxury SUV in a time where a family sedan like the Toyota Crown has up to 340 hp hybrid engine? I have my opinion, and everyone in this page have their opinion, too.
