A genuinely good restaurant can take an ingredient everyone already knows well, a roast chicken, a simple loaf, and turn it into something worth queuing for, through nothing more than technique and presentation. The Bovensiepen Spider is exactly that kind of dish. Underneath the carbon garnish and the designer plating sits a BMW Z4, roasted a little longer and served on much nicer china, for a price that assumes you won’t ask what’s actually in the pot.
A Familiar Silhouette, Freshly Dressed
The long bonnet, the cockpit set well back, the short overhangs: these have defined the Z4’s shape since its first generation, and they define the Spider’s shape too. What’s new comes from designer Frank Stephenson, brought in to add a gloss-black front splitter with a double blade, enlarged front wheel-arch vents, a stretched rear spoiler and 20-inch forged wheels. It’s a genuinely handsome piece of restyling, confident rather than fussy, even if the proportions underneath give away exactly what’s on the plate.
Under the Bonnet: A Careful Reheat
Power comes from the familiar 3.0-litre twin-scroll turbo straight-six, the B58, fitted with a de-restricted intake with a ram-air duct and a four-outlet stainless steel sports exhaust. The result is 320 kW, or 435 PS, and 580 Nm of torque, enough for 0-100 km/h in 4.2 seconds and a limited top speed of 260 km/h, 295 km/h with the optional performance package. An eight-speed ZF automatic, retuned for sharper shifts in Sport mode, sends the power to the rear wheels. Worth noting for anyone reading the menu closely: the standard Z4 M40i already makes 340 PS from the same engine, and a basic chip tune gets well past 450 PS for a fraction of the outlay, so the extra seasoning here is deliberately mild rather than fiery, a curious restraint given Buchloe’s own history of building cars that quietly humiliated BMW’s own M division on the road.
A Cabin That Asks You to Order Extras
Inside, a low, well-integrated driving position sets the tone properly. Standard upholstery is Vernasca leather and Alcantara, with a Lavalina leather-trimmed steering wheel from the in-house saddlery. Anyone wanting the full leather treatment, leather-trimmed dashboard or Alcantara footwells pays extra for it, a slightly odd choice on a car that already starts well north of 115,000 euros and could reasonably have made its own signature material standard throughout the cabin rather than confined to the wheel rim alone.
On the Road: Refinement Over Fireworks
Bovensiepen calls its approach „Fine Driving,“ and the Spider backs that up with a carefully sorted chassis and a fabric soft top that keeps the roadster feeling properly purist rather than gadget-laden. This isn’t a car chasing lap times; at 1,585 kg DIN kerb weight and 3.6 kg per PS, it sits comfortably rather than aggressively in its class, with 281 litres of boot space that covers a weekend away and little more. The retuned eight-speed automatic and the sports exhaust’s four tailpipes add theatre to the experience without pretending the car is something it fundamentally isn’t, a track weapon in a roadster’s clothing.
A Third Course From the Same Kitchen
The Spider is the third dish this particular kitchen has sent out, after the 05 GT and the Zagato, and the pattern holds across all three: take a well-known BMW base, apply serious design and craft on top, and charge accordingly. The founders, Andreas and Florian Bovensiepen, run a genuinely small operation out of Buchloe, and that scale shows in the attention to detail rather than in outright horsepower bragging rights, a choice that will please some diners and frustrate others expecting something wilder.
Verdict: A Dish Worth Ordering, If You Know What You’re Paying For
At 115,500 euros for 99 hand-built examples, the Spider isn’t selling raw pace, since a tuned standard Z4 could out-muscle it for less. What it sells is presentation: a genuinely talented designer’s touch, in-house leatherwork, and the scarcity of a very short production run. Order it knowing exactly that going in, and the meal turns out to be a genuinely satisfying one. Order it expecting a completely different recipe underneath, and the bill for reheated familiarity might sting rather more than the plating suggests it should.
