How to save battery on BMW i4?
To maximize battery range in your BMW i4, focus on both driving habits and vehicle settings. Start by switching to ECO PRO mode – it smartly adjusts acceleration response and aircon usage to stretch those extra kilometers. Make the most of the regenerative braking system too; in city traffic, one-pedal driving really cuts down on brake wear and helps top up the battery. With Malaysia's heat, keep the AC between 23-25°C and use recirculation mode. For longer drives, pre-cool the cabin using the My BMW App before you set off – it saves energy compared to cranking up the AC while driving.
Don't overlook tire pressure – keeping it between 2.4-2.6 bar reduces rolling resistance, which is key for efficiency. Charging overnight? Plug in between midnight and 8 AM to take advantage of off-peak electricity rates – much easier on the wallet. Here's a pro tip for tropical climates: avoid leaving the lithium battery at 100% charge for extended periods. Stick to an 80% daily charge to help maintain battery health long-term.
Since Malaysia's got its fair share of hills, plan your routes to prioritize highways when possible, and use the navigation system's range prediction feature to stay ahead. Combine all these tricks with BMW's clever battery thermal management, and you'll be getting the absolute most out of your electric driving experience.

Q
How many miles can a BMW i4 last?
When it comes to the BMW i4, a pure electric ride, how long it lasts boils down to two big factors: the battery pack's durability and how you drive and take care of it day in and day out. From what BMW's official figures and the industry standards tell us, under normal driving conditions, the i4's battery should hold up for roughly 150,000 to 200,000 miles (that's about 240,000 to 320,000 kilometers) before its capacity might start to dip down to 70-80% of what it was brand new. But even then, it'll still be good to roll.
Now, for our friends in Malaysia, that hot weather could potentially put a bit more strain on the battery life. But here's the thing: BMW's Battery Management System (BMS) does a solid job of keeping the temperature in check. A pro tip? Stick to regular maintenance schedules and try not to rely too much on fast charging if you want to squeeze more life out of that battery.
Another plus with EVs like the i4? Their mechanical setup is way simpler than your old-school gas guzzlers.

Q
How often should I service my i4?
When it comes to servicing your BMW i4, you'll want to stick to BMW's official recommendations: a routine service every 12 months or 10,000 to 15,000 kilometers, whichever comes first. Since the i4 is an all-electric ride, its maintenance needs are a bit different from your typical gas-powered Bimmer. The focus shifts more towards checking the battery system, electric motor, cooling setup, and brakes. That means longer intervals between services and generally lower costs – nice, right?
Living here in Malaysia with our hot and humid weather, it’s extra important to keep an eye on the battery cooling system and high-voltage components. Trust me, that extra attention goes a long way in keeping your i4 running smoothly for the long haul. And while you won’t be changing engine oil or oil filters anymore (say goodbye to those!), you still need to regularly check things like brake fluid, coolant, and the cabin air filter – those are still wear-and-tear items.
A quick tip: your i4 will actually remind you when it’s time for service, either through the infotainment system or the My BMW app. And when that time comes, do yourself a favor and head to an authorized BMW service center. They’ll use genuine parts and have the proper diagnostic tools, which is not only best for your car but also crucial if you want to keep that warranty valid. Let’s be real, regular servicing isn’t just about avoiding breakdowns – it’s about keeping that battery healthy and helping your i4 hold onto its value down the line. Smart move all around.
Q
Is it okay to charge an i4 to 100 every time?
When it comes to whether you should charge your BMW i4 to 100% every time, from a battery health standpoint, it's advisable to avoid frequent full charges in daily use, especially when using fast charging. Keeping the battery at 100% for extended periods can accelerate lithium battery degradation. The ideal approach is to maintain a charge level between 80% and 90% for your daily commute, and only fully charge it before long trips to maximize range.
For Malaysian users, the impact of the hot climate on battery life requires extra attention. When charging in high-temperature conditions, it's recommended to choose a shaded area and avoid direct sunlight. Additionally, utilize the vehicle's preset charging limit function (if available) to protect the battery.
It's worth noting that modern EV battery management systems are quite intelligent. Even when it shows 100% charge, the system typically reserves a buffer space. However, actively controlling your charging habits can still extend battery lifespan. If you frequently need to drive long distances, regular full charges are acceptable, but if you mainly use the car for short urban trips, keeping a moderate charge level is more battery-friendly.
Q
Does I4 mean turbo?
So, you're wondering if "I4" means turbo? Let's break it down. I4 stands for Inline-4, which refers to the engine's layout – four cylinders arranged in a straight line. But here's the thing: that layout alone doesn't tell you if it's turbocharged. An I4 can be naturally aspirated (NA) or turbocharged; it all comes down to the manufacturer's design and tech choices.
In the Malaysian market, plenty of brands like Proton, Perodua, Toyota, and Honda offer models with I4 engines. Some of these do pack turbo power to boost performance and fuel efficiency – think the Proton X50's 1.5T GDI mill or the turbocharged 1.8L in the Toyota Corolla Cross. Turbos work by compressing incoming air, cranking up power output – perfect if you crave a more spirited drive. On the flip side, naturally aspirated I4s often shine with smoother power delivery and lower maintenance costs.
So which one should you pick? It boils down to your needs. Turbocharged I4s are great if you enjoy a sportier, more aggressive driving style, while NAs tend to be the reliable workhorses for daily commuting. Malaysian buyers should weigh up factors like budget, how they'll use the car, and personal preference when choosing between these two setups.

It’s a setup that really shines in Malaysia’s mix of stop-and-go city traffic and open highway cruising.
Reliability? It’s proven itself in markets worldwide, and maintenance costs sit at a reasonable level for a luxury brand. Here’s the thing about Malaysia, though—our hot climate is tough on turbocharged engines, especially when it comes to cooling. But BMW’s dialed in the I4’s cooling system specifically for this kind of heat and humidity, so it stays steady even when the mercury spikes.
If you’re someone who cares about driving feel but also needs day-to-day practicality, the I4 engine checks a lot of boxes. It’s smooth, responsive, and holds its own against rivals in its class. A quick tip for anyone eyeing one: stick with factory-approved oil and keep up with regular servicing. That’s how you’ll keep that engine performing at its best for the long haul.
Q
Can an BMW i4 beat a v8?
The question of whether the i4 can "beat" a V8 really comes down to which specific models you're comparing and, more importantly, how you plan to use the car. Take the BMW i4, for instance. As a pure electric vehicle, its instant torque delivery and acceleration can definitely outshine some naturally aspirated V8 fuel-powered vehicle, especially off the line and in short sprints. The electric motor's immediate power response translates to that gut-punching acceleration – the i4 M50, for example, hits 100km/h in just 3.9 seconds, which can absolutely hang with a fair number of V8 performance cars.
But here's the thing: a V8 engine's ability to deliver sustained power at high revs and that intoxicating exhaust note? That's something electric cars still struggle to replicate. Especially during high-speed cruising or when you're really pushing it on a track for extended periods, the character and stamina of a big-displacement, multi-cylinder engine still shine through.
For folks in Malaysia, you've also got to factor in the real-world ownership experience. Things like how widespread charging infrastructure is and your typical driving range needs – the i4's range and how quickly you can top it up might end up being limiting factors.
Technologically speaking, the i4 represents the exciting future of new energy, while the V8 stands for that timeless mechanical allure. They both have their merits. If you're someone who values environmental friendliness and cutting-edge tech, the i4 makes a strong case. But if raw, emotional driving thrills are what you're after, the V8 is still a classic choice for good reason.
It's worth noting that as motor and battery tech keep advancing, EV performance is getting closer and closer to – and sometimes even surpassing – traditional fuel-powered vehicle. But that unique charm of an internal combustion engine? I don't see that disappearing anytime soon.

Latest Q&A
Q
What does gear size mean?
Gear size refers to the geometric characteristics of gears calculated through core parameters such as module, number of teeth, and pressure angle, which essentially reflect the physical specifications and meshing capability of gears. As a fundamental parameter, the module (m) is defined as the ratio of the pitch to the circumference π (m = p/π), directly determining the tooth height and tooth thickness. For example, the tooth height of a gear with a module of 0.5 is 1.125 mm (2.25 × 0.5), while that of a gear with a module of 1.0 doubles to 2.25 mm. Gear size calculation covers key data such as reference circle diameter (d = mz) and addendum circle diameter (da = d + 2m). For instance, the reference circle diameter of a gear with 16 teeth and a module of 0.4 is 6.4 mm. It should be noted that gears that mesh with each other must have the same module; otherwise, normal transmission cannot be achieved. The standardized design of gear sizes (such as the module series specified in JIS B 1701) ensures manufacturing compatibility, while the modified gear technology can adjust the center distance to meet non-standard requirements. These parameters collectively affect the torque transmission efficiency and mechanical strength of gears, and are core considerations in the design of transmission systems such as automotive gearboxes.
Q
What is the gear ratio of 1 to 7?
The gear ratios from 1st to 7th gear in an automobile transmission refer to the rotational speed ratio between the input shaft and the output shaft at each gear position. Their numerical design directly affects the vehicle's power output and fuel efficiency. Taking manual transmissions as an example, the 1st gear ratio is usually between 3.0:1 and 5.0:1, achieving high torque output through a large gear ratio, which is suitable for starting or climbing. As the gear position increases, the gear ratio gradually decreases. For instance, the 5th gear ratio is approximately 0.7:1 to 1.0:1, while the 6th or 7th gear (more common in high-performance or energy-efficient models) may further drop to around 0.6:1 to reduce the engine speed during high-speed cruising. The gear ratio distribution logic of automatic transmissions is similar, but the specific values vary due to differences in brand technologies. For example, the 1st gear ratio of some 7-speed dual-clutch transmissions is about 4.7:1, and the 7th gear ratio may be 0.6:1. It should be noted that the actual gear ratio is comprehensively influenced by the vehicle's positioning, engine characteristics, and final drive ratio. For example, the low gear ratios of commercial vehicles may be as high as 6:1 or more to meet heavy-load requirements, while the overdrive gear is designed to improve fuel economy through a gear ratio of less than 1. It is recommended to consult the technical manual of the specific vehicle model to obtain accurate data.
Q
What is the D4 on a car?
D4 is a gear identifier for automatic transmission vehicles, indicating that the transmission can automatically shift between gears 1 and 4, making it suitable for most daily driving scenarios. During normal driving, the system automatically selects the appropriate gear based on vehicle speed, engine RPM, and road conditions. For instance, it starts in first gear and progressively shifts up to fourth gear as speed increases to optimize power delivery and fuel efficiency. Common automatic transmission gear positions include P (Park), R (Reverse), N (Neutral), and D (Drive). Within the Drive mode, sub-modes like D3 restrict the transmission to third gear maximum, which is ideal for hill climbing or overtaking, while D4 is better suited for steady-state driving conditions such as highway cruising. In certain vehicle models, D4 may also refer to engine technology specifications—Toyota's D4-series engines, for example, employ direct fuel injection—though this interpretation depends on specific model context. While proper use of D4 enhances driving smoothness, switching to lower gears is recommended in challenging conditions (e.g., steep inclines or heavy traffic) to maintain better vehicle control.
Q
What does the 1/2/3 mean on my car's gear shift?
The numbers 1, 2, and 3 on a car's gear shift typically appear in manual transmission vehicles or the manual mode of automatic transmissions, each representing different gear ratios and power output ranges. Gear 1 is the starting gear, providing maximum torque, suitable for moving the vehicle from a standstill or climbing steep slopes. Gear 2 is used for low-speed driving or gentle inclines, serving as a transition between Gear 1 and Gear 3. Gear 3 is suitable for medium-speed driving, such as urban roads or situations with speeds between 40 to 60 kilometers per hour. These numbered gears adjust the relationship between engine speed and wheel speed to achieve more efficient power delivery and fuel economy. For automatic transmission vehicles with manual mode (e.g., M or S mode), drivers can manually select gears 1 through 3 to handle specific road conditions, such as using lower gears during long descents to employ engine braking and reduce brake system strain. Proper understanding and use of these numbered gears can improve driving safety while optimizing vehicle performance.
Q
How do you calculate gears?
There are three main methods for calculating the gear ratio. The first is based on the number of gear teeth, with the formula: gear ratio = number of teeth of the driven gear ÷ number of teeth of the driving gear. For example, if the driving gear has 20 teeth and the driven gear has 40 teeth, the gear ratio is 2:1, meaning that for every full rotation of the driving gear, the driven gear rotates half a turn. The second method uses the inverse relationship of rotational speeds, with the formula: i = rotational speed of the driving gear ÷ rotational speed of the driven gear = number of teeth of the driven gear ÷ number of teeth of the driving gear. If the driving gear rotates at 3000 rpm and the driven gear at 1500 rpm, the gear ratio is also 2:1. The third method combines torque and power parameters, with the formula: transmission ratio = operating torque ÷ (9550 ÷ motor power) × motor input speed ÷ service factor, which requires integrating motor performance and operating condition data.
Gear ratio design directly affects vehicle performance. A large gear ratio (e.g., 1st gear) is suitable for climbing or heavy loads, as it increases torque but sacrifices speed. A small gear ratio (e.g., 5th gear) is beneficial for high-speed cruising and reducing fuel consumption. Modern transmissions optimize shift smoothness and fuel efficiency through multi-speed dense gear ratios (e.g., 8-speed transmissions). Additionally, electronic gear ratio technology can improve control precision by adjusting the pulse equivalent—for instance, optimizing the pulse equivalent from 2.44 μm/pulse to 1 μm/pulse can significantly enhance machining accuracy. A reasonable gear ratio configuration needs to balance power output, fuel economy, and driving comfort.
