The BMW X7 from dAHLer Competition Line

The BMW X7 isn’t a small car, it’s probably the largest BMW ever made at 5.16 meters long, 2.00 meters wide, 1.80 meters high its overall weight is at least 2.4 tons, so she’s massive, but also a true BMW when it comes to driving dynamics, and that’s exactly what Swiss-based dAHLer wanted to emphasize when they created their Competition Line package for this gargantuan SUV.

The engineers at dAHLer Competition Line started out by liberating the thundering sound of the large 4.4-Liter V8 twin-turbo engine, so a quartet of massive exhaust tips show the work put into a custom exhaust that releases the growl from the front into the world, and the X7 from dAHLer roars with a simply beguiling sound.

The base for this impressive dAHLer modified BMW comes from the X7 M50i, as there isn’t a real X7 M from Germany at this moment, dAHLer Competition line offers a pair of power upgrades that should satisfy your needs, and if the base X7 was built before July 2020 they even remove the electronic speed limiter, unfortunately, that is no longer possible on the later model.

The Stage 1 boost takes the G07 X7 M50i standard 390 kW (530 hp), 750 Nm (553 ft-lb) 4.4-Liter Biturbo V8 up to a more impressive 463 kW (630 hp) and 830 Nm (612 ft-lb). But wait, there is more, dAHLer is already working on Stage 2, and with that, they promise 475 kW (646 hp) and 850 Nm (627 ft-lb), and just in case you don’t happen to own the top of the line X7 M50i, dAHLer even offers their performance upgrades for the other gasoline-powered X7 models, and even the diesel-engined ones.

As you probably noticed from the photos, this X7 comes with a lowering module for the factory original dual-axle air suspension with an automatic leveling system that fitted on all X7 models by BMW, not only does it look amazing, it also lowers the center of gravity that’s so troublesome on all high-riding SUV models, hence it improves driving dynamics.

The wheels on this demo BMW X7 by dAHLer Competition Line are massive 23-inch CDC1 FORGED units, these are weight-optimized and reduce the unsprung and rotating mass despite being 11-inch wide, as can be expected, these wheels can be finished in any shade the client desires, dAHLer advises the fitment of 295/35R23 tires, but if you prefer a staggered look, you can also opt for 285/35R23 on the front axle and massively wide 325/30R23 on the rear axle, which is what I would go for the be honest.

The car in these photos is even more special, dAHLer calls it the ‘Edition Dark Shadow’, and they intend to build only 500 units of this special unit, this car comes with a matt finished body and a glossy black rear diffuser and M-look mirror covers, naturally, the interior hasn’t been overlooked either, and aside from custom mats and a nice pedal set, the speedometer has been extended to 330 Km/h.

M340i xDrive DCL dAHLer competition line

The BMW M340i comes from the factory as a ‘Mild Hybrid’, this means there is a starter-generator and a battery added to reduce fuel consumption and increase overall power output, the 48-volt adds up to 11 hp (8 kW) to the normal combustion engine to get you off the line quicker during acceleration, in this model the engine is the B58 unit with 374 hp (275 kW) and 500 Nm of torque.

But Dahler Competition Line AG from Bern, Switzerland, takes this mild hybrid to another level after their overhaul, which is available in two levels, the Power Boost level 1 brings power output to an impressive 435 hp (320 kW) and torque up to 610 Nm (450 ft-lb), and as this tuning is WLTP-E6d tested and approved for sale in the EU and Switzerland, you even keep the factory warranty on your brand new BMW M340i.

Going for the Power Boos level 2 ‘powered by dAHLer’ option will get you to 455 hp (334 kW) and 640 Nm (472 ft-lb) and will in the near future come with an increased setting for the top speed limiter, but you’ll could run into some issues with the factory warranty from BMW themselves, so that’s a risk you might need to take in this case.

To make sure the looks of the BMW M340i dAHLer fit the sound from the exhaust, you might want to get their stainless steel exhaust system, specially tuned to the series GPF. It comes with quad ceramic-coated 90mm tailpipes, a top-quality ceramic coating is not only highly practical, with outstanding features such as hardness and resistance to wear, electrical insulation, low thermal conductivity, and a consistently reproducible surface structure, it also has a highly refined look.

Dahler Competition Line AG is also preparing an Eventuri intake system and they offer an additional, CAN bus-controlled exhaust valve controller so you can have a more subtle sound when you drive in the city, but unleash the sporty, signature dAHLer sound on the highway.

If your BMW M340i comes with the EDC Electronic Damping System from the factory, you can install an upcoming Competition coilover suspension “Built by dAHLer” with DDC plug and play, but for now, they already offer a Competition coilover suspension that can be manually adjustable in height and hardness, however, if you’re only going for looks, a set of sport springs is also a possibility.

But you will have to get a set of ultra-light 20-inch “dAHLer CDC1 FORGED” wheels, 9×20 inches at the front with 235/35ZR20 tires and 10×20 inches at the rear with 275/30ZR20 tires (Michelin Pilot Sport 4S) to finish of the mild aero tuning from dAHLer in the form of a front splitter, a rear spoiler, special M Style mirror caps, a carbon-fiber roof antenna cover, and a front grille design in three different looks.

Dähler BMW X5 M50i

The BMW X5 is a large SUV in European standards, it might not be considered large in the United States market, but you have to admit the M50i version that comes with a 4.4-Liter twin-turbocharged V8 engine with 530hp and 750 Nm (553 lb-ft) of torque isn’t underpowered, but there is also an X5 M available with even more power … 600hp and a 0 to 60mph time of only 3.8 seconds, for a large SUV that weighs 5,425 lbs, that’s a train coming down the street at that speed.

But what if you want something a little different than a factory original X5 M, and preferably with more power? In comes Dähler Competition Line AG, located in Switzerland, they offer a ‘Power boost level 1’ option for the cheaper X50i model (MSRP $82,800 against $105,100 for the X5 M) that boosts the power from 530hp to 630hp and adds 90Nm on top too, 840Nm in total now, which betters the X5 M from BMW.

And the best part is that, even with the increased, limited top speed of 270 km/h, the X5 M50i DCL Dähler Competition Line has been WLTP-E6d-temp tested and approved for sale in the EU and Switzerland, with a corresponding supplementary warranty in addition to factory warranty … but wait, there is more … Dähler is already working on a ‘Power boost level 2’ package that promises even more power … 700hp here we come.

The X5 M50i “babbles” and “blubbers” with the unmistakable, unadulterated V8 sound that so many fans love, and Dähler created a 4-pipe stainless steel exhaust system for their car, with four ceramic-coated tailpipes that show some impressive size … 101mm in diameter, not only does it look amazing, it also works in perfect harmony with the factory-installed gasoline particulate filters (GPF).

Unfortunately, the CAN bus-controlled valves in the exhaust, allowing the driver to control the sound level at any rpm or speed, isn’t EU/CH approved, so you can’t use it on the open road … but it will wake up the neighbors if you start your Dähler BMW X50i in the morning with the valves open.

The BMW X5 M50i comes with an EDC electronic damping system, so the lowering springs from Dähler had to be custom made for this car, they not only lower the car to the tarmac, but they also increase driving stability, decrease rolling movements … and they just make the car look better, at the moment Dähler is even working on a complete coilover suspension that will come with adjustable height and hardness.

Standard fitment on the BMW X5 M50i are 20-inch wheels, the X5 M comes with 21-inch from the factory … naturally, Dähler had to top those, so they came up with massive 23-inch forged wheels, called CDC1 FORGED these 11-inch wide wheels receive massive 305/30 R23 tires, and they are still up to 35% lighter than conventional light-alloy wheels.
