Q
What is the idle mode of the Mercedes R-Class?
The idle mode of the Mercedes R-Class typically refers to the state where the engine maintains a low rotational speed (approximately 600-800 rpm) while stationary, allowing electrical systems like air conditioning and audio to continue operating. Equipped with either M272 or M273 engines featuring electronic throttle control, the vehicle automatically adjusts idle speed to ensure smooth operation and minimize vibrations.
For variants with the ECO Start/Stop system (available in certain international models), the engine automatically shuts off under specific conditions (such as when braking or stationary) to conserve fuel, restarting upon brake release. While idling with air conditioning is common in Malaysia's hot climate, prolonged idling may increase carbon buildup risk - occasional brief operation at 2000 rpm is recommended to help clear deposits.
Mercedes' sophisticated idle control technology generally prevents noticeable vibrations or unstable rpm, though abnormal symptoms (excessive rpm fluctuation) may indicate throttle body contamination or sensor malfunction requiring dealership inspection. As a premium family vehicle, the R-Class performs well in idle refinement with superior noise suppression and smoothness compared to conventional models, complemented by smooth power delivery when stationary thanks to its 7G-Tronic transmission.

The Mercedes-Benz R 63 AMG (W251) has an electronically limited top speed of 250 km/h, a traditional speed restriction for AMG models, though its powertrain potential could theoretically achieve higher velocities. This high-performance MPV is powered by a 6.2L V8 naturally aspirated engine (M156) producing 510 horsepower and 630 Nm of torque, paired with an AMG SpeedShift 7-speed automatic transmission that enables a 0-100 km/h sprint in just 4.6 seconds - remarkable performance for a 7-seat luxury tourer.
Under Malaysian road conditions, such capability far exceeds practical requirements while significantly increasing fuel consumption (combined cycle approximately 6-7 km/L). Notably, the R 63 AMG maintains stability even at high speeds, supported by its AMG sport suspension, large brake systems, and refined aerodynamic design.
Although now the Mercedes-Benz R 63 AMG is discontinued, this model is still a popular collector's item for those seeking both performance and practicality in the used vehicle market. However, as one of AMG's more special creations, the R 63 AMG is rare in Malaysia.
Q
Is Mercedes R-Class equipped with air suspension system?
The Mercedes R-Class is equipped with an air suspension system. As an advanced suspension technology, it significantly enhances both ride comfort and handling performance.

Q
How Many CC is Proton Persona?
The Proton Persona has a displacement of 1597 cc. CC (Cubic Centimeter) is equivalent to a cubic centimeter and is the same as a milliliter (mL). In the automotive field, it is used to represent the engine's displacement. All models of the Proton Persona are equipped with a 1.6 - liter displacement engine. The intake form is natural aspiration (NA), and the cylinder arrangement is an in - line 4 - cylinder. The engine's maximum horsepower is 109 PS, the maximum power is 80 kW, the maximum power speed is 5750 rpm, the maximum torque is 150 N·m, and the maximum torque speed is 4000 rpm. Such a power configuration can meet the needs of daily urban commuting and general road driving. Different versions of the models vary in terms of configuration, comfort, etc., but the core engine displacement remains the same.
Q
What is the Engine in Proton Persona?
Currently, the Proton Persona is equipped with a 1.6-liter naturally aspirated four-cylinder gasoline engine, codenamed CamPro IAFM+. This engine is independently developed by Proton. It has a maximum output power of 107 horsepower (about 80 kilowatts) and a torque of 150 Newton-meters. It is paired with either a 5-speed manual transmission or a CVT continuously variable transmission. The overall performance is smooth, and its fuel economy is suitable for daily driving.
The CamPro series of engines is one of Proton's signature technologies. The IAFM+ (Intelligent Air-Fuel Module with Variable Length Intake Manifold) technology enhances the low-speed torque performance by optimizing the intake efficiency, which meets the driving needs of the multi-urban road conditions in Malaysia. It's worth mentioning that since Proton collaborated with Geely in recent years, some new models have started to adopt turbocharging technology. However, as an economy car, the Persona still continues with the mature and stable naturally aspirated configuration. This setup is more attractive to local consumers in terms of maintenance cost and reliability.
If you have higher requirements for power, you can pay attention to Proton's models equipped with the 1.5TGDI turbocharged engine. Nevertheless, the Persona is more positioned towards practicality and cost-effectiveness, making it suitable for family users who focus on daily commuting.
Q
What is the Gearbox Type of Proton Persona?
The Proton Persona comes with two types of transmissions: MT (Manual Transmission) and CVT (Continuously Variable Transmission). Some models of the 2019 version are equipped with the MT gearbox. It has a simple structure, can withstand large instantaneous torque, and delivers outstanding power performance. Most other models from different years are mainly fitted with the CVT transmission, which performs well in terms of smoothness and fuel - efficiency. During driving, gear shifts are smooth, and it can effectively reduce fuel consumption, providing drivers with a comfortable driving experience. Different transmission types meet the diverse needs of consumers. The MT is suitable for drivers who enjoy the fun of manual control, while the CVT is more popular among users who pursue a smooth driving feeling.
