Deemed the Bugatti Veyron of the Sea (we’d actually take the XSR48 over a Veyron anyday), the exotic XSR48 Superboat is capable of producing 1600hp from two bi-turbo diesel engines and can even push out 2400hp through an optional two bi-turbo gas powered Supercharged V8. Under the sleek supercar-inspired exterior lies the luxurious cabin which is surrounded in a contemporary setting with plush furniture and various other amenities. Overall, the XSR48 is a stunning feat of design and engineering and anyone with wallets big enough to tackle the price tag on one of these machines should definitely get their checkbook ready. [$2.4m]
