Cadillac's New Celestiq Night Test Looks Like A $400,000 Secret

Cadillac’s most expensive car has gone even darker. The latest hand-built Celestiq wears a deep midnight-blue finish, dark wheels and almost no bright trim. Cadillac calls this one-off the Night Test, and it looks more like a private luxury lounge than a traditional electric sedan.

The Celestiq already stands far apart from the rest of Cadillac’s lineup. Since deliveries began last summer, the ultra-luxury EV has slowly made its way to a small group of wealthy customers. Each car receives plenty of attention to detail, but this particular 2027 model takes the bespoke approach even further.

Cadillac says the Night Test draws inspiration from its racing heritage. The exterior uses a deep blue paint with dark two-tone wheels, while the usual shiny trim gives way to subtle accents that keep the whole car looking low-key. It’s a clever direction for a car that usually makes a statement from a mile away.

The same theme continues inside. Black and white seats create the main contrast, with vertical detailing running through the center sections. Metallic trim adds some texture around the doors, while carbon fiber appears on the center console. The huge glass roof remains, as do the two individual rear seats that turn the back of the Celestiq into a much more private space.

Cadillac describes the Night Test as a one-of-one creation built around a single design vision. The company says every surface and material contributes to the car’s quiet, disciplined character. That sounds like Cadillac’s way of saying the owner wanted something expensive without making it look flashy.

That kind of customization comes at a price. The Celestiq already costs around $350,000, and this specially commissioned example likely pushes the final bill toward $400,000.

Underneath, the 2027 Cadillac Celestiq Night Test packs some serious hardware. A 111-kWh battery powers two electric motors and all four wheels, producing 655 hp and 646 lb-ft of torque. Despite stretching 217.2 inches from nose to tail, the big Cadillac can hit 60 mph in 3.7 seconds. It can also travel roughly 303 miles on a full charge.

The cabin brings just as much technology. A massive 55-inch display stretches across the dashboard, joined by an 11-inch Front Command Center and an 8-inch Rear Command Center. Rear passengers get their own 12.6-inch screens, while Cadillac’s Super Cruise system handles much of the driving on compatible roads.

The Night Test shows what happens when Cadillac gives a customer almost complete freedom to shape a Celestiq. The result doesn’t need wild colors or excessive chrome to stand out. Its appeal comes from restraint, and for a $400,000 hand-built EV, that might be exactly the point.
