2013 BMW M135i by Tuningwerk

Posted on by +  

Tuner, tuner on the wall, who is fastest of them all? Tuningwerk from Germany just launched its upgrades for the factory BMW M135i hatch, a body style and trim name not sold in America. This upgrade goes far beyond engine management, with big changes under the hood, in the suspension and on the limited-slip diff out back.

Power is a quoted 355 horsepower for the light upgrade, and a whopping 443 horsepower with everything included. From a posh commuter car, this Tuningwerk M135i is a triple threat with its monster sprint pace, high-speed overtaking power that is on par with supercars , and its track and racing prowess

In the magic world of aftermarket performance, verified claims are always hard to nail down.

Even so, an extra 50 or more Tuningwerk horsepower creates quite a handful of a sports car, and one that is so powerful that driving it safely on the road can become part of the thrill and challenge.

Tuningwerk really cranks up the menace of the BMW 1 Series , and this humble hatchback is suddenly a lot more like the ‘breadvan’ Z3 M Coupe as a real banshee of power over-steer.

All good things. After all, hatchback car guy is grumpy when trouncing big Audi’s or Porsche ’s in stoplight drag races.

Tuningwerk Exterior Upgrades

It is always amazing how much lowered springs, larger wheels and a big brake kit can transform a relatively normal car into something much more special.

The transformation in this case leverages the original BMW ’s trendy new paint finish, but drops any remaining brightwork and includes a variety of contrast black pieces for the grille, lower air dams, and diffuser shroud out back.

Gloss-black wheels look great, but appear to have a slightly atypical camber setup from some angles. Bright red BMW M brake calipers look sharp on the otherwise grey M135i, creating a simple yet purposeful overhaul of the car’s hatchback style.

No doubt these enhancements would look even better on the closest equivalent American-market option: the 135i coupe and cabrio.

Black detailing is a nice touch.

Tuningwerk Interior Upgrades

The interior of the Tuningwerk project really loses the plot. Way too much 3M Di-Noc wraps much of the interior in a fake carbon fiber that really is not classy or a good long-term upgrade. The irony of wrapping panels in carbon style finish is that they become extremely delicate and fragile. A sharp fingernail will unravel lots of hard work.

The irony? Real carbon-fiber cabin accents are virtually indestructible!

Giant and ferocious racing seats are the real deal, and will be a punishing experience for biggies. A full racing roll cage is available, but probably far too involved for most people. Once you take any car interior apart completely to put a roll cage in, it will never feel quite right again as panels and interior pieces begin to work their way free.

Anyway, black Alcantara suede is a more welcome and tasteful addition, but the real focus for Tuningwerk clients is big power and handling gains.

Drivetrain, Engine and Brakes

Here’s the big action. In addition to a remapped and enhanced boost manager for the single turbo of the straight-six M135i, the Tuningwerk project adds a freer-breathing intake, an additional charge cooler for the turbo and a giant downpipe. As the auto world will enjoy next summer, the potential power of this engine is far, far beyond the current production cap of about 330 horsepower.

In theory, this engine is every bit as strong as the Nissan GT-R’s, so Tuningwerk’s power claims are not totally outrageous. From 355 horsepower to 443, the M135i becomes something completely different when the boost really hits.

Mini car, monster power. Fun times. A limited-slip differential, the big brakes kit, and KW Clubsport that are something called "inbuilt triple adjustable."

As good as lower and adjustable suspensions sound before installation, finding that perfect factory bliss again can be very tricky.

Conclusion

BMW M135i by Tuningwerk

Very few people have ever said, "Hey, my 135i is not quite fast enough and will almost never drift."

But adding more of both of those things is almost a sure recipe for making any car better. This M135i by Tuningwerk is actually a legitimate mechanical enhancement package, turning the fast a sporty 1 Series into a supercar chase vehicle.

LOVE IT
  • Looks really sharp and strong
  • Dynamic images of Tuningwerk M135i on track shows this puppy can handle
  • Just that little extra shove in the back versus the already-potent M135i
LEAVE IT
  • Unknown pricing, availablilty outside Germany, and long-term reliability of the tunes and components
  • Super sporty ‘Breadvan’ look is cool, but not an imported style over in the States
  • Paint is very refined and subtle considering the amount of terrifying pace on offer

The TUNINGWERK M135i VERSION

The top model of the recent BMW 1 series, the M135i with its exhaust gas turbo charged straight-six-engine, offers a quite excellent optimization starting basis for track day and street. Thus, nevertheless, sounds the credo of the Bavarian TUNINGWERK GmbH at Puchheim, west of Munich.

Tuningwerk Performance Upgrades

To take the relatively unspectacularly looking gray BMW M135i for a gray mouse could be a fatal error. Oftentimes, starting point no. 1 is the factory-set software, so also in this case. Moreover, the engine of the test car (with manual gear) is equipped by a two kgs lighter dual mass flywheel. Optionally, there is also available a single mass flywheel with about 4,5 kgs of weight economy and, also, a reinforced clutch. Both of these options are not possible for automatic gears.

Moreover, there are a modified turbo charger and an enlarged intercooler in function. On the left in the engine compartment has been installed an additional water cooler. The Puchheim experts have integrated a down pipe with 200 cells cat into the exhaust system, what is not serial, too. Depending on modification or configuration level, it is possible to reach an output of 360 to 450 PS (265 to 331 kW).

For aims of better driving dynamics, the TUNINGWERK masters have inbuilt triple adjustable KW Clubsport suspensions and also a limited slip differential on the rear axle. The front axle has been equipped by 245/40R18 and the rear axle by 265/35R18 Dunlop Direzza semi slicks having caused a lightly wings pull out. Additionally, there has been installed a BMW performance braking system with TUNINGWERK racing brake pads and steel flex pipes. The warm state braking values reach incredible 33 meters (about 100 ft.).

Tuningwerk Cockpit Upgrades

The interior design underlines the sportive ambitions of the TUNINGWERK M135i. Thanks to its adjusting opportunities, the Recaro pole position seats with in-house seat foundation allow also very big drivers to drive with hardhat. Optionally, a driver’s cage is also available.

During the first test drives on the Hockenheim GP course the „little sportsman“ made by TUNINGWERK has reached a remarkable 1:58 lap time.
