Hi Tadgh,

Indeed, 2.0-litre petrol engines in regular cars are going out of fashion, but you'll find many smaller petrol engines with turbocharging that are just as powerful. For example, the 1.5 TSI engine in the current Skoda Octavia makes 150hp and can tow up to 1,500kg. As a new car, that's just outside your budget, but you've not told us how new you mean, and what type of car you are looking for. Most that are towing a lot go for SUVs, 4x4s or estates, though you don't have to. 

Come back to us with a little more information and we'll do our best to steer you towards a good solution.
