New Forester/Standing Load

Dear Subaru fans! I’m new here in the forum and would like to welcome everyone! I really like the new Forester design, which also goes more towards SUV/road car. Unfortunately, according to my research, the car is only offered with a 150 hp petrol engine. In combination with automatic transmission (with me is basic condition, manual transmission I think nowadays for anachronism) the towing load is only 1500 kg! That is completely unacceptable for me, must have an 18 kg. 00 kg trailer pull! Is there no stronger engine for the car? Subaru builds otherwise great engines, which also bring good performance, see the 6-cylinder boxer in the outback! Or do you still have to wait a bit, because stronger engines are only in preparation? Please look forward to every constructive answer! Greeting Nissan driver
