Yacht builders are designing zero-emissions yachts to compete with diesel-chugging rivals. They’re so quiet you can hear dolphins swim by.

On October 23, the auction house will present more than 230 automobiles from a single collection, including a couple of extremely rare examples.

The examples from Superformance and Downforce Motorsports will be available when their 1,200-mile road rally finishes on October 11.

The X-Expedition Cruise has much larger staterooms than a traditional cruise ship, offering a more private, exclusive experience.

Starting at $350,000, this utility vehicle from 1949 now comes with 350 hp and 600 ft lbs of torque.

The rare vehicles, once owned by privateer racer Marcel Petitjean, will be offered at an RM Sotheby’s online-only event.

Starting May 21, the nine-day sale will include two cars from Maranello that could fetch more than $2 million each.

Rescued from flames, the 540K Special Roadster has a revised history that may light a fire under prospective buyers.

With a body by Pinin Farina, the 250 GT Berlinetta Prototipo on offer carries an asking price of approximately $1.4 million.

Offered privately through Gooding & Company, this 1964 Porsche 904 Carrera GTS has its original engine.
