The modern roadster is becoming an endangered species, largely because car makers keep asking it to justify itself with spreadsheets. Two seats? A fabric roof? Barely enough luggage room for a determined weekend? The accountants see inefficiency. The rest of us see a Tuesday evening transformed by one unnecessary detour.
Enter the Bovensiepen Spider, a 99-car act of cheerful defiance from Buchloe. BMW wound up Z4 production earlier this year, but the appetite for a long bonnet, a straight-six and some sky above your head has plainly survived the factory shutdown. Bovensiepen has read the room — admittedly, a very wealthy room — and decided that the answer to roadster scarcity is more craftsmanship, more power and far fewer examples.
A sports car with its priorities facing forwards
Look at the shape and the message is wonderfully uncomplicated. The bonnet stretches out, the cockpit sits well back and the overhangs are clipped short. There is no attempt to make this thing resemble a crossover that has misplaced its roof. Frank Stephenson collaborated on the exterior components, and the proportions make the Spider feel like a celebration of the familiar rather than a desperate hunt for novelty.
That matters. Too many expensive cars now compete by stacking visual drama upon visual drama until every surface appears to be shouting into a ring light. The Spider takes the more grown-up route. It is low, clean and confident enough to let the basic roadster silhouette do the work. Familiarity is not a crime when the familiar thing is this handsome.
The straight-six is the whole point
Bovensiepen’s preliminary figures put the turbocharged straight-six at 435 PS and 580 Nm. Those numbers are stout without becoming cartoonish, but the more revealing figure is the claimed power-to-weight ratio of 3.6kg per PS. This is a roadster, after all. It should feel alert and alive, not like a cruise missile carrying a conservatory.
The engineering changes sound pleasingly focused. Bovensiepen has opened up the intake path, added a ram-air channel, enlarged the intake silencer and reduced restriction through its sports exhaust. The suspension receives retuned dampers and longer auxiliary springs at the rear. None of that guarantees magic, but it shows attention being spent where enthusiasts can appreciate it: response, control and character.
On the manufacturer’s provisional numbers, 0–100km/h takes 4.2 seconds and the standard top speed is 260km/h. A Performance Package raises that ceiling to 295km/h, aided by extra differential cooling and an underbody V-brace. Almost nobody needs that. Marvellous. Sports cars lose their sparkle when every feature must survive a household budget meeting.
Exclusivity is the clever bit — and the annoying bit
Only 99 Spiders are planned, each hand-built. That instantly gives the car occasion and protects Bovensiepen from pretending it wants to fight Porsche at industrial scale. The family business has deep engineering roots, an authorised BMW service operation and a Buchloe base where low-volume attention to detail is a credible proposition rather than brochure perfume.
Yet the number also exposes the frustration at the heart of this car. The Spider represents precisely the sort of simple, charismatic idea enthusiasts keep requesting, then places it beyond the reach of almost everybody who would adore it. That is the boutique-car bargain: a specialist can build what a giant manufacturer no longer will, but only by making scarcity part of the product.
A glorious refusal to move on
The Spider will not rescue affordable open-top motoring, and it is not trying to. Its value is symbolic. In a market filling with tall bodies, filtered controls and power outputs deployed mainly for internet bragging, here is a compact two-seater shaped around an engine, a driver and the possibility of good weather.
Bovensiepen could have chased fashion. Instead, it has built a beautifully old-fashioned argument with modern engineering underneath it. Ninety-nine buyers will get the keys. Everyone else gets something nearly as useful: proof that the roadster is not dead. It is merely hiding in Buchloe, avoiding the accountants and waiting for the sun.
