Look, here’s the deal. The Bovensiepen family—the same guys who spent decades creating something truly exceptional out of BMW called Alpina, until the Bavarians snatched the brand—are back in the game. They are now operating under the Bovensiepen name, and their new Z4-based Spider roadster is a massive slap in the face to the corporate machine in Munich.

Frank Stevenson completely overhauled Externook. Yes, the same madman who designed the brutalist brick X5 and the old-school rocket carrier Z8. All that remains of the pitiful civilian Z4 are the door handles. The face now looks like the car wants to eat you alive, and a titanium Akrapovič maw sticks out the back, a roar that will drown out any playlist.

We went through the engineering with a sledgehammer. The stock B58 «six-cylinder» was tuned up to 435 horsepower and 580 Nm of torque. The roof? It’s a heavy-duty folding mechanism that tucks itself into the trunk in 20 seconds while you’re stopped at a light and tapping your fingers. This beast hits 100 mph in 4.2 seconds.

But the juiciest part is the context in which this entire story unfolds. While Munich managers in dull ties are charting electric car sales, the Bovensiepen family first rolled out a Zagato coupe based on a four-cylinder with a monstrous 611-horsepower engine, and now this ultimate cabriolet. In the end, they simply take the best donor components from BMW, reassemble them without fear or apology, and sell them to those who understand the difference between factory stamping and true engineering finesse.

This is pure, high-octane testosterone for those who are sick of an eco-friendly future. If you wanted to buy a new Alpina—forget it. Better to give a fortune to the legacy heirs and get a car that sounds louder than your problems.
