Marque promised a flagship, and it delivered in the most literal sense.

Lexus has unveiled its ‘fourth flagship’ and, well, it’s not quite what we expected. The LY650 is based on the Lexus Sport Yacht concept from 2017, taking the brand’s design ethos and giving it a distinctly nautical bent.

The company says the ship’s strong bow, broad hips, flowing roof line, and curved deck accents accurately move the company’s L-finesse design theme from the road to the water.

The yacht is easily the biggest Lexus vehicle to date. It measures 19.96 metres, or just over 65 feet, in length, hence the name, and is 5.72m wide. It has three staterooms, and can sleep up to six people. Makes the LS look a bit pedestrian, doesn’t it?

According to the company, Shigeki Tomoyama, one of Toyota’s executive vice presidents, drove the LY project out of a desire to “present a dream-like vision of the luxury lifestyle, one where the Lexus Yacht expands the potential of Lexus mobility to the ocean”.

The LY650 comes standard with a 12.8-litre common-rail straight-six Volvo Penta IPS1200 diesel engine, which makes 588kW of power thanks to a twin-entry turbo and a supercharger. A 735kW 12.8-litre Volvo Penta IPS1350 diesel engine is available at extra cost.

The LY650 will be built, sold and serviced by the Marquis-Larson Boat Group, which is based in the village of Pulaski in Wisconsin.

Lexus expects the first LY650 to completed by the second half of 2019, and the boat will make its official debut towards the tail-end of the year.
