And slower engine speeds translate into further reduced fuel consumption and emissions. All BRABUS ECO PowerXtra® kits are backed by the one-of-a-kind BRABUS Tuning Warranty® of up to three years up to 100,000 kilometers/62,000 miles (see BRABUS warranty conditions as of November 2006).

During the development of the new ECO PowerXtra® modules the BRABUS engine specialists focus strongly on increasing torque at low engine speeds. During everyday driving the BRABUS-tuned common-rail turbodiesel engines always demonstrated much better pulling power from low rpm. During normal driving, the vehicle can usually be operated one or two gears higher than the production car. The need for downshifting during acceleration is also reduced.

The results are not just excellent performance but thanks to the slower engine speeds better fuel economy and reduced emissions. All BRABUS ECO PowerXtra® kits meet strict Euro 4 emission limits and all can be also installed in vehicles equipped with diesel particulate filter. The new with BRABUS ECO PowerXtra D6 BLUE performance kit for the Mercedes E 300 BLUETEC makes BRABUS the first automobile tuner to meet ultra-stringent EURO V exhaust limits which won’t go into effect until 2011.

Depending on the specific model, BRABUS ECO PowerXtra® kits increase maximum power output by up to 53 hp (52 hp SAE net) / 39 kW and peak torque by up to 100 Nm (74 lb-ft). The plug-and-play-type auxiliary control modules can be installed by any authorized Mercedes-Benz dealer in less than an hour.

To ensure the greatest possible safety for both driver and vehicle, the C-Tronic® Diesel POWER has correction maps that guarantee the engine's reserves are only used when the operating parameters are within the appropriate range. Thus, the coolant temperature is monitored and the additional power only generated when the engine is running at a temperature between 65° and 100° C. Additionally, two microprocessors ensure the optimum settings are selected regardless of the operating conditions.

Carlsson C-Tronic® CD 22 for C/E 220 CDI engines
The new generation of C-Tronic® performance kits for four-cylinder CDI models of the C and E Classes provide a power increase of 34 bhp. Thus, the engine generates 204 instead of 170 bhp and a torque of 480 instead of 400 Nm. The result is a second off the time for the 0-100 km/h dash and a reduction of no less than seven seconds in the 80 – 180 km/h time.

Carlsson C-Tronic® CD 32 for all 320 CDI engines
The Carlsson C-Tronic® CD 32 has been developed for all Mercedes Benz models fitted with the current basic 320 CDI engine. The increase in power amounts to 42 bhp so that the modified engine produces 269 compared to 224 bhp. Torque rises to a massive 612 Nm, which is available from 1,600 to 2,300 rpm. No less impressive are the performance figures, which improve by around a second for the sprint from 0 to 100 km/h.

Easy installation with works warranty
Thanks to the new plug & drive installation, the Carlsson C-Tronic® is quick and easy to fit. The vehicle can be returned to standard without difficulty at any time and the precise multi-dimensional map-based control ensures an immediate engine response and significantly more driving pleasure. Carlsson gives a three-year warranty on the new generation of C-Tronic® supplementary control units.

Greater driving pleasure – with a clear conscience
The environment also benefits from the C-Tronic® Diesel performance kits. Through the intelligent use of modern technology, the C-Tronic® reduces average fuel consumption by up to 10 %. At the same time, pollutant emissions, e.g., environmentally harmful exhaust gases, such as CO2 and NOX, are slashed by around 10 %.

Naturally, the C-Tronic® meets the special requirements of the particle filter in full and also shows the technological advantage of Carlsson engineering: the C-Tronic® takes account of all important data from the particle-filter system, e.g., exhaust back pressure, exhaust temperature, when generating the increase in power to utilise them in the interests of a cleaner environment.
