AC Schnitzer Tuning Program for BMW Z4 (E89)

Under the hood, Schnitzer upgraded the turbocharged 3.0-liter engine (sDrive35i) so it now produces 360 hp. Thanks to the extra 60 hp, the Z4 accelerates from 0-100 km/h in 4.9 seconds before hitting a top speed of 286 km/h (178 mph).
Other performance modifications include a stainless steel sport exhaust system (with chromed 'racing' tailpipes) and a revised suspension.
To enhance the Z4's good looks, Schnitzer added an aerodynamic body kit with a new front spoiler, a chrome grille, aggressive front fenders (with integrated air vents), and a two-piece rear spoiler. The styling can be further accented by a wide variety of custom AC Schnitzer wheels available in 18, 19 or 20 inches.
Inside, the company adds an aluminum cover for the iDrive controller and an aluminum pedal set.

BMW M3 E92 V10 by Manhart Racing

As the lengthy name implies, Manhart has shoehorned the M5/M6's 5.0-liter V10 engine into a M3 coupe. The company didn't stop there as they removed the speed limiter and added a seven-speed SMG gearbox, a DME steering system, and a titanium exhaust with four 84mm (3.3") tailpipes. Thanks to all these modifications, the 550 hp M3 V10 accelerates from 0-100 km/h in 3.9 seconds before topping out at 334 km/h (208 mph).
In terms of styling, Manhart outfitted the car with new front and rear spoilers, a rear diffuser, a Bilstein coilover suspension, and 20-inch BBS 'Challenge R' wheels. Inside, the company added carbon fiber trim, alcantara and leather upholstery, and a new steering wheel "with illuminated rocker switches, ¼ mile and side acceleration displays."

Hamann Tycoon EVO Based on BMW X6

Way back in January tuner HAMANN unveiled a new TYCOON wide body kit for the BMW X6. For the upcoming Frankfurt Motor Show the company will showcase the latest version of this model called the TYCOON EVO. Visual differences with its predecessor include new front wings, LED daytime running lights and side skirts that widen the body by 60mm.

The rear is dominated by the new sporty exhaust system with its centre double tailpipes. HAMANN promises that its sound is particularly throaty for exceptional aural pleasantries. In its vicinity are back wing extensions and a roof spoiler. Fitted to keep it on tar are special ultra-forged and polished 23-inch wheels wearing 315/25 R 23 size rubber.

No HAMANN car is complete without the engineers delving deep under the belly to unearth something more potent than what the factory offers. At the bottom of the petrol range is the xDrive35i which normally has a healthy 225kW (306hp) and 400Nm. This has been increased to 265kW (360hp) and 540Nm respectively. As such, the speed limit increases to 275km/h (171mph).

The diesel derived from the xDrive30d which usually has 173kW (235hp) and 520Nm, now has 195kW (265hp) and a flying 600Nm of torque. The second diesel motor from the xDrive35d has had its power and torque increased to 235kW (320hp) and torque to 660Nm from an early 2,000rpm.

At the top end is the xDrive50i-based V8 which has been convinced to churn out 368kW (500hp) at 5,600rpm and 700Nm of torque. It will almost hit 300km/h (186mph) if left unchecked.

HAMANN will kit out the interior with such things as a three-spoke steering wheel, aluminum foot pedals and lots of carbon fibre pieces.
