BMW X6 M Stealth by Inside Performance

Inside Performance has unveiled their new BMW X6 M Stealth. Looking anything but stealth-like, the crossover has an AC Schnitzer wide body kit and a camouflaged-inspired wrap. There's also a gloss black grille, a KW coilover suspension and 22-inch Vorsteiner wheels with Continental Sport tires.
Moving on to the interior, Inside Performance has installed a data display that shows everything from boost pressure to the current torque and power outputs.
Speaking of the latter, the twin-turbo 4.4-liter V8 engine has been equipped with an optimized ECU and a stainless steel sports exhaust system. Thanks to these tweaks the engine develops more than 700 HP (515 kW) and 850 Nm (627 lb-ft) of torque.

BMW M5 by Switzer Performance

Switzer Performance has launched an upgrade kit for the BMW M5 (F10) available for 6,995 USD. The tuner has taken a break from its aftermarket programs for the Nissan GT-R and various Porsche models to focus on the German high-performance sedan. The car's soundtrack has been improved thanks to a new high-performance, stainless steel exhaust system.

It also features high-flow drop-in air filters and a removable engine control module working together with the stock systems for a higher boost from the engine's twin turbos. While the standard BMW M5's V8 4.4-liter twin-turbo produces 560 HP (412 kW) and 502 lb-ft (680 Nm), the version modified by Switzer churns 700 HP (515 kW) and 640 lb-ft (867 Nm).

The tuner has also announced starting this summer they will offer carbon-nano brake pads and Signature alloys for all 2013MY (and later) M5s.

Leib M3 GT 500 based on BMW M3

Leib Engineering recently launched an upgrade kit for the BMW M3 E92. They installed a proprietary high-grade steel exhaust system with a 100-cell HJS catalyzer and an X-pipe with middle silencers, end muffler and an M-key to control the sound. It lifted the output of the engine by 27.5 bhp (20.5 kW) while via engine software they were able to squeeze an additional 25 bhp (18.6 kW), for a grand total of 470 bhp (350 kW).

To stop the car efficiently the tuner fitted a Brembo braking kit with six-piston calipers and 380 x 32mm discs on the front axle and four-piston calipers with 320 x 28mm discs at the back. The high-performance coupe rides on 19-inch BMW M220 forged alloys with Michelin Pilot Sport Cup semi-slicks measuring 235/35 R19 front and 265/30 R19 rear.

In addition, Leib Engineering has developed a software update for the dual clutch gearbox and they say shifting times have been reduced. The ABS software was also tweaked and should enable shorter braking distances as it was customized to work specifically with semi-slicks.

BMW 1-Series F20 by Lumma Design

Lumma Design has recently launched a body kit for the BMW 1-Series (F20). The 1-Series is considered by many the least desirable model in BMW's lineup due to its rather awkward front fascia. Lumma Design has tried to improve the hatchback's looks by adding a front spoiler lip available for the variant without the M-Technik package. Priced at 249 EUR, the spoiler lip is easy to install and can be pre-painted upon request.

They are also providing a set of lowering springs for an additional 269 EUR which bring the 1-Series closer to the road by 35 mm. The stripe set seen in these photos costs 179 EUR and is available in a variety of colors.

Inside you can opt for anodized aluminum pedals (220 EUR) which have a non-slip surface or for velour floor mats with the tuner's logo priced at 179 EUR. As a final touch, Lumma Design can fit your 1-Series with 18-inch anthracite-polished wheels covered by 215/40 R18 tires. The wheels + tires kit costs 1,700 EUR.

BMW M5 by Hamann

Well known German tuning firm Hamann has decided to give the BMW M5 (F10) a whole new identity which surely won't be appreciated by many people.

The tuner is no stranger to aftermarket kits for the M5 but unfortunately things keep getting worse. While the first one was not bad at all, the Mi5Sion package showed in Geneva earlier this month left a lot to be desired. However, we might have to reconsider our opinion after seeing Hamann’s latest M5-based project.

This more extreme variant was displayed at the Auto Trader Live luxury car show in Dubai where it shocked the crowd with its in-depth customization. Just about everything on the outside has changed, including the double kidney grille, ventilated hood, double rear spoilers and diffuser. The cabin is a blend of Alcantara and leather in black, red and light blue colors.

It seems there is a market for such a car as Hamann plans to make 10 units, each priced at 235,000 USD.

BMW M6 (F13) by G-Power

Following a preview last November, G-Power has released complete details about their upgrade program for the BMW M6 Coupe (F13). The Bi-Tronik III power kit increases output of the V8 4.4-liter twin-turbo engine from 560 HP (412 kW) and 680 Nm (501 lb-ft) to 640 HP (471 kW) and 777 Nm (573 lb-ft).

As a result of these changes, the M6 will reach 62 mph (100 km/h) from a standstill in only 3.8 seconds (0.4s quicker than stock model), on its way to a top speed of 196 mph (315 km/h), whereas the standard model with M Driver's Package can reach 189 mph (305 km/h).

It sits on 21-inch Silverstone RS alloys by G Power shod in Michelin Super Sport tires measuring 265/30 ZR21 front and 305/25 ZR21 rear. Other changes include a coilover suspension, in-house ceramic braking system and a custom titanium exhaust system which is 12 kg (26.4 lbs) lighter than the standard one and comes with 100mm carbon tailpipes.

The power boost will set you back 5,200 EUR, ceramic braking kit (front axle) is 14,460 EUR, wheels + tires combo is 8,325 EUR, while the coilover suspension is an extra 2,179 EUR. If you want the aforementioned titanium exhaust system prepare 5,985 EUR.

Hamann BMW M6 Mirr6r

German tuner Hamann has brought its BMW M6 Mirr6r to this year's Geneva Motor Show. Based on the latest BMW M6 Coupe, this custom version has received a new aerodynamic package with wider wings, rear spoiler, air intakes, side skirts and a built-in carbon fiber rear diffuser. The latter works together with the carbon fiber rear spoiler to guarantee an optimal airflow. We should mention the diffuser houses two stainless steel tailpipes on both sides.

The vehicle sits on 21-inch Unique Forged Formula or Edition Race alloy wheels with Vredestein Ultrac Vorti R tires measuring 265/30 ZR21 front and 305/25 ZR21 rear. The suspension has received sport springs that bring the M6 Coupe closer to the ground by 35mm.

As for the interior cabin, Hamann used a lot of Alcantara and they installed aluminum pedals and foot rest. Illuminated chrome trims as well as other types of materials are also available upon request.

Alpina XD3 Biturbo

Alpina has presented its own take on the BMW X3 today at the kickoff of the 2013 Geneva Motor Show. At its heart is a straight-six, full-aluminum 3.0-liter engine with two turbochargers, common-rail direct injection and variable turbine geometry. It has a maximum output of 350 HP (257 kW) at 4,000 rpm and a peak torque of 700 Nm (516 lb-ft) reached between 1,500 and 3,000 rpm.

Despite the powerful engine, the Alpina XD3 Biturbo manages to have a fuel consumption of only 6.8 liters / 100 km (41.5 mpg US or 34.5 mpg UK) while CO2 emissions stand at 180 g/km. This was possible thanks to the ZF eight-speed automatic transmission designed specifically for this model.

Other highlights of this heavily modified X3 include electronically-adjustable dampers, 20-inch Alpina Classic wheels with Michelin Pilot Super Sport low-profile tires, custom exhaust manifold, stainless steel exhaust system with dual double-ended tailpipes, along with several interior enhancements such as a sport steering wheel with blue/green stitching, door sills, floor mats, gear indicator and a digital speed read-out.

Lumma Design CLR 6 M

Following last year's preview, Lumma Design has fully revealed the BMW CLR 6 M which will be showcased in Geneva next week.

Changes include a carbon fiber bonnet sporting dual vents, a redesigned front spoiler and more generous air intakes. The back shows a new diffuser and a custom stainless steel exhaust system with a quad-pipe configuration. Each pipe has a 100mm diameter and is made from carbon fiber, just like the rear wing.

To make room for the 21-inch alloys they had to install front and rear wheel arch extensions. These rims are shod in 275/30 R21 tires at the front and 325/25 R21 at the back.

Lumma Design mentions the body kit is compatible with all F12 and F13 6-Series models, from the 640i to the range-topping M6.

BMW 6-Series GranCoupe by Hartge

Hartge has developed an aftermarket program for the BMW 6-Series GranCoupe 640i and 640d models. In its standard configuration, the inline-six 3.0-liter turbocharged engine of the 640i produces 320 HP (235 kW) and 450 Nm (332 lb-ft), but with Hartge's modifications it outputs 367 HP (270 kW) at 5,900 rpm and 520 Nm (383 lb-ft) reached at 2,950 rpm.

The 640d makes use of a 3.0-liter diesel generating 313 HP (230 kW) and 630 Nm (465 lb-ft). After making the necessary tweaks, Hartge was able to raise its output to 362 HP (266 kW) at 4,400 rpm and 730 Nm (538 lb-ft) at 1,800 rpm.

The additional power was possible by increasing the airflow by using an in-house stainless steel exhaust system with Hartge's stainless steel middle and rear silencers with dual 80mm round tailpipes.

Aside from the power boost, the 640i can be fitted with sports springs lowering the four-door coupe by 25 mm and 20 mm (front/rear). The 640d can also be lowered by 30 mm and 25 mm, respectively. The exterior packs the tuner's emblem on the hood and boot lid, while inside the car receives bespoke floor mats, aluminum emblem on the steering wheel and aluminum pedals. Various wheels are available in different styles and sizes.

BMW M3 by RS Racing

RS-Racingteam has introduced a new tuning program for the BMW M3. Designed to deliver "more adrenaline for your senses," the RS-M3 is a track-focused model that features an adjustable sports suspension, a rear spoiler and 19-inch alloy wheels. While the exterior is fairly restrained, the cabin loses the rear seat, carpeting and door pads. RS Racing then adds a roll cage, carbon fiber door panels and sports seats with six-point harnesses. Thanks to these modifications, the RS-M3 weighs 190 kg (419 lbs) less than the standard model.

Under the hood, the 4.0-liter V8 engine has been tuned to produce 450 HP (331 kW) and 431 Nm (318 lb-ft) of torque. This enables the car to accelerate from 0-100 km/h in 4.6 seconds, 0-200 km/h in 14.7 seconds and onto a top speed of 299 km/h (186 mph). The RS-M3 is currently available and pricing starts at €80,000 ($106,760).
