The new BMW Z4 is a good looking car. I wasn’t really convinced about that initially, as the pictures don’t really do it color. After spending some time with it, especially in the top-dog guise, M40i, I was convinced otherwise. The thing is, tuners make it look even better, while also adding a bit of power to the mix. After seeing what Manhart plans to do with it, we’re now checking out what Dahler came up with.

The Swiss tuner released a couple of photos of the car this week and it is, as usual, an all-black ordeal. The Dahler Z4 comes in black, with black leather and a couple of grey accents here and there. In usual fashion, the changes are subtle and I kind-of like that on a tuned car. A sleeper works better for me than a full-on, heavily modified car that would attract more attention. Being underestimated feels better on the long run.

Since this is the European model we’re talking about, the B58 engine under the hood makes 340 HP and 500 Nm (369 lb-ft) of torque on the M40i. That’s in standard guise. The Dahler version takes things up to 408 HP and 620 Nm (457 lb-ft) of torque. That’s with the OPF intact, mind you. If that’s what they can do with the car in European-spec, the US version could probably reach 450 HP. Unfortunately, they didn’t provide a new 0-100 km/h (62 mph) acceleration time but they do claim the car will be able to do 300 km/h (186 mph) now.

The car also got a new exhaust with 90 mm (3.5-in) tailpipes, new lowering springs and a couple of splitters both up front and round the back. The 21″ wheels wrapped in Michelin 245/30 and 295/25 rubber might be a bit too much though, as I found the 19″ wheels to be pushing it already, in terms of stiffness. It’s a great overall package though, as Dahler got us used to.
