In 2018, the horsepower output of the Volvo XC90 depends on the engine model you choose. The T5 version, which is common in the Malaysian market, is equipped with a 2.0-liter turbocharged four-cylinder engine that can produce approximately 250 horsepower. The T6 version, on the other hand, uses a 2.0-liter turbocharged + supercharged dual-charging system, reaching 316 horsepower. The top-of-the-line T8 plug-in hybrid version has a combined horsepower of up to approximately 407, demonstrating Volvo's strength in high-efficiency powertrain technology. For Malaysian consumers, the horsepower performance of the XC90 is more than enough to meet the diverse local road conditions. Whether it's for city commuting or long-distance travel, it can provide ample power. It's worth mentioning that Volvo's Drive-E engine series is well-known for its modular design. Through different tuning, it can balance performance and fuel economy. This technical concept also enables the XC90 to remain competitive in the luxury SUV market. The hot climate in Malaysia places high demands on the engine's heat dissipation performance. The XC90's turbocharging system is equipped with advanced intercooler technology, which can effectively maintain the stability of power output.

The 2018 Volvo XC90 doesn't feature a wet belt design. Instead, it uses a more traditional timing chain. This kind of chain is usually located inside the engine and lubricated by engine oil. It has a longer service life and higher reliability, and generally doesn't need to be replaced regularly like a belt. Wet belts are commonly seen in small - displacement engines of some European brands. They run while being immersed in engine oil, but there may be an issue of aging after long - term use. The timing chain is more suitable for the durability requirements of large SUVs like the XC90. For Malaysian car owners, the timing chain has lower maintenance costs and is more suitable for the local hot and humid climate, as chains aren't as susceptible to high temperatures and humidity as belts. However, regardless of which timing system is used, regularly checking the engine oil condition and having timely maintenance are still the keys to ensuring the long - term stable operation of the engine. It is recommended that car owners follow the maintenance cycle recommended by Volvo and use engine oil that meets the specifications to maximize the engine's lifespan.

The 2018 Volvo XC90 does come with the Head-Up Display (HUD) feature in some high - end models. This technology can project crucial driving information such as vehicle speed and navigation instructions onto the windshield, allowing drivers to access the information without looking down, which improves driving safety. It's particularly suitable for the congested city traffic in Malaysia and long - distance driving scenarios. However, the HUD was not standard across all models. It ​​was typically found on higher trims​​ or ​​as part of an optional package​​. It is recommended that potential buyers carefully check the configuration list or consult local dealers to confirm the specific configuration of the vehicle they're interested in. Regarding the Head - Up Display technology, it was first used in the aviation field and has now become a common feature in luxury cars. Besides Volvo, brands like BMW and Mercedes - Benz also widely adopt it. Different brands' HUDs have their own characteristics in terms of projection brightness, information richness, and customization functions, but the core purpose is to reduce the driver's line - of - sight deviation. This technology also adapts well to the strong sunlight in Malaysia's hot climate because most HUD systems have an automatic brightness adjustment function. If you're interested in the XC90, you can also pay attention to other safety technologies introduced around the same time, such as the City Safety system and Pilot Assist semi - autonomous driving assistance. These features together reflect Volvo's brand concept centered around safety.

Among the configurations of the 2018 Volvo XC90 available in the Malaysian market, some high - end models (such as the Inscription or R - Design versions) can be optionally equipped with an Air Suspension system. However, it is not a standard feature across the whole range. You need to confirm this based on the actual sales configuration list or the owner's manual of that year. The air suspension can change the vehicle's body height by adjusting air pressure, which can enhance comfort (such as filtering out bumps) or practicality (such as lowering the loading height of the trunk), making it suitable for Malaysia's diverse road conditions. If your vehicle is equipped with this function, you can adjust it in the "Driving Mode" or "Chassis Settings" on the central control screen. However, be aware that the long - term maintenance cost is relatively high (for example, the airbags need to be replaced when they age). Similar configurations are also commonly offered in German luxury SUVs of the same class, such as the Mercedes - Benz GLE or the BMW X5. Volvo's tuning is more inclined towards the Nordic comfort style, which is suitable for family users. If you're buying a used XC90, it is recommended to check if the suspension airbags are leaking by lifting the vehicle or to check the original factory maintenance records to confirm the configuration.

The 2018 Volvo XC90 available in the Malaysian market is mainly powered by a 2.0-liter four-cylinder turbocharged and supercharged twin-charged engine (T6 version) and a 2.0-liter four-cylinder turbocharged plug-in hybrid system (T8 version). There are no V6 or V8 engine options. In recent years, Volvo has been committed to the research and development of environmental-friendly and efficient powertrain technologies. Therefore, all its models are based on four-cylinder engines. By combining turbocharging, supercharging and hybrid technologies, it has achieved performance comparable to that of traditional six-cylinder or eight-cylinder engines while taking fuel economy into account. For Malaysian consumers, the T6 version of the XC90 has an output of around 320 horsepower, and the combined output of the T8 hybrid version can reach up to around 400 horsepower, which can fully meet the needs of daily driving and long-distance travel. In addition, Volvo's Drive-E powertrain system performs excellently in terms of reliability and environmental protection, meeting the increasingly strict global emission standards. If you're interested in luxury SUVs with larger displacements, you can also consider V6 or V8 models offered by other brands. However, the advantage of the XC90 lies in its balanced performance, advanced safety technology and the luxurious feel of Nordic design.
