Satria Neo Powertrain Delivers Better Performance With Improved Engine Management

Proton Satria Neo is powered by a 1.6 litre twin cam multivalve version of Proton's own CamPro engine which has been revised and developed to produce better performance and a flatter, more even torque delivery while ensuring strong fuel economy and low emission output.

Responsiveness has been improved as a result of a revised Step4 engine management program as well as better tuning and balancing of the total package.

Developed in collaboration with Lotus the CamPro is a strong, reliable, modern, fuel efficient engine and complies with stringent Euro 4 emission requirements.

The free revving 1.6 litre, multi-point fuel injected four-cylinder CamPro engine produces 82 kW of power at 6000rpm and 148Nm of torque at 4000rpm.

The lightweight all-alloy CamPro1.6 engine has a 76mm bore and an 88mm stroke with a compression ratio of 10:1.

Behind the Satria Neo's single centre mounted chrome tail pipe is an integrated exhaust system designed for silence and efficiency and to reduce noise vibration and harshness. The exhaust's improved airflow design also aids performance and fuel consumption.

The CamPro 1.6 litre engine gives Satria Neo a 0-100kmh acceleration time of 11.5 seconds and a top speed of 190km/h.

The combination of Satria Neo's revised CamPro 1.6 litre engine and a low overall kerb weight (1159 kg), allows it to achieve excellent fuel consumption of just 7.2 litres per 100kms combined average (ADR81/01).

During the development of the CamPro Proton engineers subjected the engine to more than one million kilometres of testing and development before it entered mass production.

Proton engineers subjected CamPro to more than two million kilometres of testing in the most extreme range of conditions, from the heat and dust of the Australian outback to the cold and snow of the Arctic Circle in Sweden.

Testing was conducted on engine rigs and dynamometers as well as on the road with running prototypes accumulating more than 27,000 hours of running.

A HVAC cooling test was also performed on the CamPro in Japan as Proton and Lotus engineers set out to create a bullet-proof engine designed for performance, reliability, durability and fuss free, affordable maintenance.

Lotus played a key role in CamPro helping achieve a more linear torque progression for better acceleration and driveability.

The CamPro engine in Proton's new Satria Neo is controlled by the latest generation engine management system the EMS 700 designed and built in Malaysia by Proton.

The EMS 700 interfaces with an on-board digital information display capable of presenting a range of information to the driver.

The on-board system can calculate average fuel consumption, journey time, distance to empty in kilometres.

Satria Neo has 12 months or 15,000km service intervals between oil changes.

The new car is equipped with either a five-speed manual transmission or an optional four-speed Automatic transmission.

The manual (FSM41) five speed transmission features an overdrive fifth gear along with nicely spaced ratios to give smooth seamless performance across the rev range with a final drive ratio of 4.052:1.

The electronically controlled four-speed automatic (F4 A21) has been re- calibrated to give smoother shifts and a more even power delivery with a direct drive on third and an overdrive on fourth and a final drive ratio of 4.042:1

Automatic versions of the GXR variant are fitted with Cruise Control.
