I see small cars here in Germany towing huge camping trailers all the time (ask Frank, he's Dutch, they love to town their caravans all over Germany ). And there is an old SAAB video that shows Stiq Blomqvist torwing his 99 Turbo race car with a his daily driver 99 Turbo. American tow ratings are awfully low for whatever reason. If you are worried I would install a transmission oil cooler.
