First revealed this past June at the M Drivers Club meeting at the Salzburg-Ring in Austria, BMW tuner, G-Power, has taken the ferocious 5.0L V10 engine from a BMW M5 and transplanted it to a previous generation E46 M3 CSL.

In stock form, the M3 CSL is already quite potent with 360 hp and 370 Nm of torque, however, status-quo is not the way to go for the northern Germany based tuning firm. Despite the added weight of the V10 engine, the power to weight ratio still improves from 3.9 kg/hp to 2.7 kg/hp. The engine conversion alone for G-Power is still not enough as they seduce 43hp more for a total of 550hp and 38 Nm of torque to 558 Nm. 0 to 100 km/h drops from 4.8 sec to 4.2 and 0 to 200 km/h comes in a scary 11.6 seconds. Top speed surges from 285 km/h to 335 km/h. To handle all of that brute power, G-Power turned to suspension manufacturer, KW Automotive, to extensively test and tune the suspension.

Externally, the M3 CSL is unchanged according to G-Power, however, we noticed an additional air intake hole on the passenger side of the front bumper - nice touch nonetheless. G-Power has mounted their concave 10-double spoke Silverstone Diamond wheels pictured here in 21-inch. Despite the added weight from the faux screw fittings which give a two-piece appearance, the Silverstone wheels are in fact lighter than the stock M wheels.

In addition to the E46 3 Series, G-Power offers this V10 engine conversion for the current E91 3 Series Coupe and M3 as well as the Z4 and X5. Currently in development by G-Power is a twin-supercharger kit for the 5.0L V10 engine expected to produce in entry level form 640hp and in further levels up to 750hp. No word yet on model applications for this twin-supercharged kit.

Spectacular heart transplant
spectacular modification for BMW M3 V10
550 hp / 580 Nm / Vmax: 335 km/h
perfectly tailored to higher performance tuned suspension
new SILVERSTONE wheel in 20 Zoll
G-POWER, the guarantor of three decades of high-value BMW tuning, once again demonstrates their expertise in the field of motor design modifications. Current modification is for no less a figure than the BMW M3 E46 CSL! It receives a G-POWER revised V10 motor out of the current BMW M-series. With considerably more than 500 hp, the CSL is promised more significantly improved driving performance, yet remains practically unchanged in appearance: a wolf in sheep’s clothing.

Heart transplant brings a quantum leap!
With the BMW M3 CSL, northern German refiners G-POWER present a further exemplar for BMW series vehicles equipped with V10 motors. First time vehicle presentation was held June 2007 at the Salzburg-Ring in Austria during the M Drivers Club meeting; official partners of G-POWER. The modulation of the larger V10 aggregate to the significantly smaller M3 CSL engine compartment is mastered by G-POWER with flying colours. Directly consequential to the V10 series aggregate from the M5 is a substantial increase in performance alone, yet G-POWER would not be G-POWER if there wasn’t more to be had. Pertaining to engine tuning, G-POWER’s customers benefit from 26 years of collected experience. Balancing this experience, the V10 elicits 550 hp and catapults to an acceleration of guaranteed 580Nm. In contrast to the original six-cylinder in-line engine with 360 hp and 370 Nm, the results are really quite impressive. The remaining facts are no less spectacular. Despite a somewhat higher vehicle total weight of 1550kg, G-POWER with it’s “heart tranplant” sank the power to weight ratio from a good 3,9 kg/hp to a superior 2,7 kg/hp. Instead of 4,8 seconds from 0-100 km/h, G-POWER CSL V10 reached this mark in a breath-taking 4,2 seconds. Even more important in reference to super sports cars, is the speed acceleration to 200 km/h. With 11,6 seconds, the G-POWER CSL V10 leaves all others with scarcely a chance. Often the top speed of this bolide surpasses even those more powerful engines from Stuttgart-Zuffenhausen or Maranello, Italy: 335 km/h is a quantum leap versus the 285 of the original M3 CSL!

This V10 “operation” from G-POWER is available for the complete palette of the BMW models. Whether the current 3-series coupé, Z4, X5 or new M3, G-POWER rises and meets each challenge. Additionally, G-POWER is already working on a bi-compressor kit for the V10 engine and shall be setting further milestones in the higher divisions of the distinguished BMW refinement segment. The targeted performance of the first level lays by approximately 640 hp and for those especially power hungry, further levels can liberate up to a possible 750 hp .
Clearly, for more security even further alterations on the CSL technology are necessary. Based on brute performance, G-POWER took on the suspension as well. Working closely with suspension manufacturer KW automotive, which is very succsessful in racing at Nuerburgring-Nordschleife, the northern Germans compiled an extensivey tested suspension system. It is perfecty adjusted to the car´s power and is suitable for race track and road use as well.

Wheel SILVERSTONE for CSL
G-POWER equips the otherwise externally unaltered M3 CSL with its newest wheels. G-POWER’s affinity to racing sports is clear to anyone by name alone: SILVERSTONE.

The new G-POWER SILVERSTONE DIAMOND wheel is provided a “concave” rim contour design specially developed for the latest BMW vehicle generation but suis older models such as the M3 E46 CSL perfectly as well. With this new, for G-POWER protected design, a pure BMW wheel was generated exclusively adjusted to the BMW brake outlines. Through this optimized spatial relationship, G-POWER improves additional brake ventilation. The special interpretation of multi-spoked design SILVERSTONE rims instantaneously makes the entire wheel unit exceptionally unique!

In addition, this wheel already more than satisfies the exacting safety requirements imposed by Bavarian manufacturer’s. They feature BMW stipulated run-flat capabilities in conjunction with approved tires! Furthermore, they are lighter in weight than the BMW factory M–wheels. The reduced unsprung weight has a noticable positive impact on comfort, even in conjunction with ultra low profile tires!

The new wheel, with ist striking appearance due to it’s unusual shaped 10-double spoke design, is manufactured in OEM quality. Naturally, they are “made in Germany”! Immediately eye-catching are the extravagant screw fittings that seem to signify a multiple pieced structure. Completely on the contrary though as it’s a one-pieced wheel that through its characteristics, is quite exquisite. The latest G-POWER technique of surface coating SILVERSTONE DIAMOND wheels effectively prevents brake dust and dirt from “baking” onto the wheels. This makes the wheel particularily easy to care for. The silver-graphite-coated spider with its brightly shining “diamond cut” face, creates a fascinating and dynamic effect, blending harmoniously with all BMW exterior colours. Customers acquire a wheel with a classic and stylish appearance.

The SILVERSTONE program is available in sizes 18 ” through 21” in widths from 8.5” to 10.5”. Presented here, M3 CSL rolls on SILVERSTONE 21-inch wheels.
