Tiny Slovenian supercar maker Tushek emerged out of nowhere in 2012 with its 450-horsepower (335-kilowatt) coupe, the Renovatio T500. Seven years later, and Tushek is back with a product more than twice as powerful: the TS 900 H Apex. It’s making its debut at the Salon Prive in the U.K. next month.

The Tushek TS 900 pumps out more than 900 horses, as its name implies.

It also has a removable hardtop roof – which allows you to experience all that speed sans roof – and supercar-esque scissor doors.

“The Tushek team is delighted to be back at Salon Privé,” Tushek founder and Slovenian race car driver, Aljosa Tushek, notes. “Over the past years, we have...
