You’re looking at the most luxurious Cadillac ever, the new £300k Celestiq, a limousine leviathan aimed squarely at Rolls-Royce and Bentley. What do you get for all that money? The most technologically advanced vehicle in Cadillac’s history, which means everything from a 55-inch HD screen across the dash, via trick chassis systems, to active aero. It also rides on GM’s Ultium Platform, a dedicated EV architecture that in Celestiq guise mates an 111kWh battery with two motors, for four-wheel drive and over 600bhp. Tech is only half the story though. Each Celestiq will be hand-built at the new Artisan Center [sic], at General Motors’ Global Technical Center [sic] campus, in Michigan, USA. And only after each one has been customised by the owner – in collaboration from Caddy’s designers – at the nearby Cadillac House at Vanderbilt. It’s an ultimate flagship to lead Caddy into the electric era, so we sent Top Gear’s deputy editor Ollie Kew over to America to take a look.
