2011 BMW Z4 99d by AC Schnitzer

The Geneva Motor Show is ready to crack itself open in just a few hours, but AC Schnitzer has decided to release some details on its line-up for Switzerland a little early.

The first package from the German tuner is called the Z4 99d and uses a diesel engine that delivers 190 HP and 420 NM of torque. With this amount of power, plus a weight reduction of 230 kilos (507 lbs.), the tuner has managed to obtain a 0 to 60 mph sprint time of just 6.9 seconds, while top speed is 146 mph. This performance is accompanied by a fuel consumption of 3.8 liter diesel per 100 kilometers and a CO2 emission of just 99.18 g/km.

AC Schnitzer also spent some time on the exterior of the BMW Z4 with an interesting paint job. We don’t know just how we feel about the green, blue, and black swirl paint yet, but it may just fit the BMW nicely.

UPDATE 02/28/2011: This review has been updated with the BMW Z4 99d’s full specs, as well as new images.

Exterior and Interior

For the exterior package, AC Schnitzer has opted for new lightweight composite materials such as carbon, magnesium, and titanium. The package includes a carbon front spoiler, an anodized matt silver front grille, carbon sports fenders, new bonnet vents, a 2-piece rear spoiler, carbon rear skirt insert, carbon roof, and carbon boot lid.

The AC Schnitzer 99d sits on AC Schnitzer Type VIII lightweight 19" forged BiColor rims wrapped around 225/35 ZR 19 tires. These lightweight wheels, along with the AC Schnitzer lightweight 4-pot high performance brake system, reduces the BMW’s total weight by 35kg (77lbs).

The interior received some attention as well with a new sports steering wheel, painted interior panels, carbon racing seats with the 99d logo, and aluminum foot rest and pedals.

The engine for the 99d by AC Schnitzer was borrowed from the Z4 320d EfficientDynamics Edition and after an AC Schnitzer upgrade, it now delivers a total of 190 HP and 420 Nm torque (up from a standard of 163 HP) and emits only 99g/km CO2. The emission for the 99d is less than any standard BMW vehicle available at this time. The 99d delivers a 0 to 60 mph sprint time of just 6.9 seconds, while top speed is 146 mph.

AC Schnitzer hasn’t released any details as far as pricing is concerned, so if you are interested, you’d be better off giving them a call. We imagine the complete package will knock out a few thousand from your bank account.

Since its official launch back in 2009, the BMW Z4 has seen plenty of interesting tuning packages. AC Schnitzer itself has developed other tuning packages for the Z4, with one of them improving the engine’s output to a total of 360 HP and attaining a top speed of 177 MPH.

One of the most impressive packages for the Z4 was offered by Hamann . Their package delivers a total of 360 HP at 5230 rpm and a peak torque of 540 NM available in the engine speed range of 1300 to 5000 rpm. Also, as with the previous AC Schnitzer kit, the top speed was raised to 177 mph.

  • Powerful diesel engine
  • Impressive aerodynamic package
  • Extensive use of carbon fiber
  • Quite slow for a sports roadster
  • Not sure about the swirly paint design


I must say that their paint job on the Z4 99d is totally awesome. The color combination did well on its exterior.

The combination of the colors white and green have contributed to the boost of its appeal. The paint job is done exquisitely.

Wow, very customized color paint, I like the green and gray scheme paint on the white tuning car. Definitely, one of the stunning concepts and eye-catching features.

It seems that they have made this roadster to be a less powerful car. I wonder if its remove rooftop have something to do with it.

The bad thing about diesel is that they have a less power output. Well, I’m really concerned in the speed of the car over its styling. I guess this production is a failure.

As expected from the BMW, their detailing is kind of impressive as well as its performance. IMO. comparing to the work of Hamman, this one seems to be an ordinary looking.

I would praise the awesome aerodynamic kit offer on this. However, i just don’t like the retro- styling on its body. BTW, I hope to see a better performing and lighter version of roadster.

Yeah. I have to agree that the performance of this car is quite impressive for a car that was powered with diesel. And the detailing for the exterior is great as well. BTW, it has an awesome aerodynamic kit.

Oh yes! This diesel powered car is quite powerful and the aerodynamic kit offer is impressive. Although, I think that its speed is kind of slower. BTW, I love those stickers.

What have been said in the article is contradicting! It was said that it would have a powerful engine and yet it has a slow speed. I don’t get it. BTW, the retro- styling of this car is kind of impressive.

Oh yeah! I love the sticker design of this car. The aerodynamic package is quite impressive but the engine performance is not powerful at all. I think its kind of slow since it can sprint the 60 mph for 6 sec.

Yeah, its kind of slower for a roadster, its not even worth to be called a sportscar. I think AC Schnitzer focus more on the design of this car that they almost forgot about the engine.

Well, aesthetically, I like the design especially the sticker of this car. However, i think that the engine performance is less powerful to be a sportscar.

Yeah, AC Schnitzer is also one of my favorite tuners too. Their works are actually rather simple in design, but they really fit into the base car’s image. Just take a look at their BMW’s

AC Schnitzer really never fail to impress me every time I see their works. The way they did this BMW is really rather good looking. Hope they can showcase more of their works this year.

BMW lost me on the Z4 when they dropped the M coupe and switched to a folding hard top. If the is were a soft-top and a bit better tuned suspension, I think a good portion of the review complaints would be mitigated.

the BMW Z4 is a fantastic car. It may not have the steering feel it used to, or perform as well in the slalom as I/L anticipated, but i think it still makes for an excellent sports car.
(just no more silly comments comparing it to a Mercedes SL, please).
