I lived in England for the first 40 years of my life and drove since i was 18.

I have honestly never seen or heard of a car in England that would struggle to do 75mph, unless maybe a smart car.

It is true that engines are usually smaller but then i have always thought that North American cars have ridiculous engines.

I used to have a 2.3 litre Chev Cavalier in Canada, it wasn't super fast and even if it was the roads here have a 50mph (80Km) limit for the most part so are pretty slow.

My last car in England back in 2003 was a 1.6 Vauxhall Vectra, it was a 4 door Saloon with 5 on the floor and like most cars I had in England went damn quick. The roads in England are 60mph out of town and the motorways are 70mph officially but I always found that below 85 plod left me alone.

None of my cars had big engines and none had any problems getting to 100mph.

I will add that because of the price of petrol, the first question we have for the dealership is usually what does it do to the gallon. The optimal speed for fuel economy is always quoted at 56mph and it has to be taken into account when people compare the fuel economy of European and North American cars that the US has a smaller gallon than Europe, or Canada.
