High-performance Porsche 911s are understated compared to their flamboyant Italian rivals. If you want a car that can be used daily and outperform virtually everything else on the road but without drawing too much attention, you get a nice 911 Turbo.

Now, there’s been no shortage of VW people carriers modified with a Porsche engine – but this one probably takes the cake.

That’s because this overhauled VW Multivan is powered by an actual 911 Turbo engine. This was brought to our attention by Carscoops reader Nasyr Jakypbek, who tipped us off about this sleeper that’s currently listed for sale on Mobile.de in Cologne, Germany.

From the outside, this Multivan looks just like any other. The only ‘sporty’ components it features are black wheels and tinted headlights. Step inside and everything in the Multivan also appears normal. There are two plush seats up front and two rows of two seats facing each other in the rear. It looks like a relaxing and calming place to travel around in.

However, there is one area of the interior that stands out. Look just ahead of the driver’s seat and you’ll notice a Porsche steering wheel and the gauge cluster from the 911 Turbo.

Sitting under the luggage compartment at the rear of the Multivan is where all the action is happening. Found below a hatch is the 911 Turbo engine and while the listing doesn’t say specifically which Turbo engine is used, it allegedly pumps out 581 HP.

The VW Multivan apparently cost more than 250,000 euros ($280,000) to build and has only ever traveled 16,298 km (10,127 miles). The asking price? A cool 139,800 euros ($157,000). To put this into perspective, a brand new, 992-gen 911 Carrera 4S Cabriolet has an MSRP of $133,400, excluding taxes, title, destination and delivery fees.

True, this is a people carrier that can go really, really fast and looks quite discreet from the outside – but would you spend that kind of money on it?
