Should You Buy an EV? Well, it depends. Maybe you should — but hey, I’m not here to tell you what to do. People buy new cars for all kinds of reasons, not just EVs. But if you’re getting one specifically to help the environment, there’s something important to keep in mind — and not many people think about it when shopping for a new car. It’s kind of like that time I bought a reusable water bottle to be more eco-conscious...then lost it after a week and never actually used it. Not exactly the eco-friendly move, right? (don’t worry, now I have a reusable bottle which I actually use 🙂) The truth is, making new stuff — cars included — usually isn’t great for the environment. So if you’re going to buy one, make sure it’s something you really need and that you’re actually going to use it the right way. Say you’re thinking about swapping your current car for a brand new EV — you know, doing your bit for the planet, cutting those tailpipe emissions, and cruising in quiet, guilt-free style. Good move, right? Well...mostly. But before you ditch your current ride, there are a few things you might not be aware of. Lifecycle Emissions: The Big Picture Like the fact that building an EV actually creates more CO₂ than building a regular petrol or diesel car , largely due to the energy-intensive production of lithium-ion batteries. According to the International Energy Agency (IEA), while EVs are far cleaner to operate, they typically start off with a larger carbon footprint than internal combustion engine vehicles. So while electric cars are undeniably cleaner to drive, the picture’s a bit more complicated when you zoom out and look at the whole lifecycle. The Comparison: Petrol vs EV Let’s say you currently drive a VW Tiguan, BMW 3 Series, or a similar car. It’s got some years on it, but it runs well — which is no surprise, especially if you service it at BM Tech  😊. You drive about 15,000 km a year, mostly around the city and suburbs. Now you’re eyeing a brand new EV. I’ll use the Tesla Model 3 Dual Motor as our benchmark — not to endorse a brand, but to keep the numbers consistent. Annual CO₂ Emissions: Petrol car:  ~205 g/km x 15,000 km = ~3.1 tonnes CO₂/year EV (charging from the Australian grid):  ~87 g/km = ~1.3 tonnes CO₂/year Sources: Australian Government - National Greenhouse Accounts Factors Electric Vehicle Council - EV Emissions Yes, EVs are cleaner to drive — even in Australia’s coal-heavy grid — but the upfront impact of production still matters. Manufacturing Emissions: The Catch Building a typical petrol SUV can emit 7–10 tonnes of CO₂ . But a similar-sized EV? More like 14–16 tonnes , mostly due to the battery. According to research published by Transport & Environment (Europe’s leading clean transport NGO), battery production accounts for a significant chunk of an EV’s lifecycle emissions — though this is improving with cleaner production methods. Since your Tiguan, Audi A4, BMW, or whatever you drive is already built, you’re not adding anything new to the environment by keeping it. But the new EV would start with a carbon footprint nearly double that of a new petrol car. That means it would take around 5–6 years  of regular driving before the EV breaks even environmentally. If it’s a bigger EV like a Kia EV9, you’re probably looking at 7+ years . So... Should You Buy One? Honestly, it depends. If your current car is still in good shape (at BM Tech we can certainly help you with that), the greenest car you can drive is the one you already own — at least for a few more years. Keeping it maintained and not trashing it early is actually more sustainable in the short term than buying a brand-new EV tomorrow. But if your plan is long-term — say, to keep your next car for 7–10 years or more  — then yes, EV will more than pay off its carbon debt. By the way, we also work on EVs at BM Tech and have qualified technicians for that. And as Australia’s grid gets cleaner in the years ahead, those emissions per km will keep dropping. So don’t feel like you need to jump into a brand-new EV just to prove you’re being eco-conscious. But if you are going to upgrade, do it with a plan to keep it for a good while — that’s when the real savings kick in. Alex Topin at BM-Tech, 2025.

Cruise control has long been celebrated for enhancing driver comfort during extended journeys. If you've ever driven from Melbourne to Lakes Entrance, for example, you will know what I mean. Beyond reducing fatigue, many drivers are curious about its impact on fuel efficiency. Does utilising cruise control lead to noticeable fuel savings? The answer isn't straightforward; it depends on various factors, including driving conditions, terrain, and the specific vehicle in use. Understanding Cruise Control Essentially, cruise control is a system that automatically maintains a vehicle's speed without continuous driver input on the accelerator pedal. Early versions mechanically locked the throttle at a set position, but modern systems are electronic and more sophisticated. Advanced variations, known as Adaptive Cruise Control (ACC), can adjust speed based on traffic conditions, maintaining a safe following distance from the vehicle ahead. Cruise Control and Fuel Efficiency The primary advantage of cruise control in terms of fuel efficiency lies in its ability to maintain a constant speed, thereby reducing unnecessary acceleration and deceleration. On flat terrains and open highways, this steadiness can lead to fuel savings. According to a study by Natural Resources Canada, setting cruise control at 80 km/h resulted in up to 20% fuel savings compared to fluctuating speeds between 75 and 85 km/h. Kia That said, however, the benefits of cruise control are not universal across all driving conditions. In hilly or mountainous terrains, cruise control may strive to maintain a set speed uphill, causing the engine to work harder and consume more fuel, not to mention the annoying noise this makes. Conversely, it might not adequately utilise engine braking downhill, leading to potential safety concerns and inefficient fuel use. In such scenarios, manual control allows the driver to anticipate changes in terrain and adjust throttle input more judiciously, optimizing fuel consumption. Adaptive Cruise Control (ACC) and Fuel Consumption Adaptive Cruise Control represents a significant advancement over traditional systems by incorporating sensors to monitor traffic and adjust speed accordingly. While ACC enhances safety and convenience, its impact on fuel efficiency is nuanced. Research from Argonne National Laboratory indicates that current ACC systems may be approximately 2% less energy-efficient than skilled human drivers, particularly during steady cruising conditions. VMS Taps This slight inefficiency arises because ACC systems react to the behaviour of preceding vehicles rather than anticipating traffic flow, leading to minor but frequent adjustments in speed. Human drivers, especially those practicing eco-driving techniques, can often predict traffic patterns and adjust their driving more smoothly, conserving fuel. Factors Influencing Fuel Efficiency with Cruise Control Terrain : As previously mentioned, flat terrains are ideal for cruise control to maximize fuel efficiency. In contrast, hilly terrains may negate its benefits. Traffic Conditions : In heavy traffic, constant speed adjustments are necessary, making cruise control less effective. It's best utilised in light traffic conditions where steady speeds are attainable. Driving Habits : Drivers who naturally maintain a steady speed may see less dramatic fuel savings from cruise control compared to those with variable speed tendencies. Vehicle Type and Technology : Modern vehicles equipped with advanced cruise control systems and fuel-efficient technologies may experience different impacts on fuel consumption compared to older models. Best Practices for Using Cruise Control Optimal Use : Engage cruise control on highways with minimal traffic and flat terrains to maximize fuel efficiency. Stay Attentive : Always remain vigilant. While cruise control manages speed, the driver is responsible for steering and monitoring road conditions. And if your cruise control sounds as if it's straining or stuck in between gears, that's a good indicator human pedal control is a better option. Adapt to Conditions : In adverse weather or on slippery roads, it's advisable to disengage cruise control to maintain full control over the vehicle. Understand Your Vehicle : Familiarise yourself with your vehicle's cruise control features and limitations by consulting the owner's manual. Conclusion Cruise control can contribute to fuel efficiency, particularly during steady-speed driving on flat highways. However, its effectiveness is influenced by terrain, traffic conditions, and individual driving habits. While it offers comfort and can reduce driver fatigue, it's essential to use cruise control judiciously and remain attentive to driving conditions.

by Alex Topin, BM Tech Piezo injectors – once considered a revolutionary breakthrough in fuel injection technology – have had quite a journey in the automotive world. From their promising debut to their eventual decline in gasoline engines, the story of piezo injectors is a fascinating tale of innovation, challenges, and practical realities. While they still have their place in some applications, they’ve taught the automotive industry an important lesson: advanced technology isn’t always the best solution for every scenario. What Are Piezo Injectors? Piezo injectors are a type of fuel injector that utilises the piezoelectric effect  – a phenomenon where certain materials generate an electrical charge when subjected to mechanical stress. This effect can be reversed, allowing these materials to change shape or deform when voltage is applied. By harnessing this property, piezo injectors can achieve ultra-fast response times, incredible precision, and multiple injection events  in a single engine cycle. The Initial Success of Piezo Injectors These qualities made piezo injectors a game-changer  when they first appeared in gasoline engines. Compared to traditional solenoid injectors , which rely on electromagnetic force to operate, piezo injectors were touted as superior in every way. Their lightning-quick response times – as low as 0.2 milliseconds  – made them ideal for advanced fuel injection strategies like stratified injection , which delivers multiple, precise fuel doses during a single stroke, improving combustion efficiency and reducing emissions. At first, the automotive world was excited. Mercedes-Benz  pioneered the use of piezo injectors in its CLS 350  models, while BMW  adopted them for its N54 engine , followed by early versions of the N55  and N63  engines. Engineers believed that piezo injectors were the future of fuel injection systems, especially for high-performance and luxury vehicles  where cutting-edge technology is a key selling point. Why Did Piezo Injectors Fail in Gasoline Engines? Despite their impressive advantages, piezo injectors quickly proved to be problematic in real-world applications , particularly in gasoline engines. Several key factors led to their decline: 1. Reliability Issues Piezo injectors are highly sensitive to high temperatures , which are common in gasoline engines. The extreme heat caused the piezoelectric crystals to degrade  over time, leading to a loss of precision and performance. Additionally, their intricate design made them prone to mechanical wear, clogging, and carbon buildup , reducing durability compared to solenoid injectors. 2. High Costs Piezo injectors are expensive to manufacture due to the high-quality materials  required and the complexity of their design. This made them a costly choice for automakers. For consumers, high replacement costs and repairs  added to the frustration. 3. Challenges in Gasoline Applications Unlike diesel engines, which operate at higher fuel pressures and lower temperatures , gasoline engines presented unique challenges that piezo injectors struggled to overcome. High operating temperatures, nozzle shape, and aging piezoelectric crystals  all contributed to their failure in many applications. The Shift Back to Solenoid Injectors As reliability and cost issues became apparent, automakers started reverting to solenoid injectors . BMW, once a strong advocate of piezo technology, transitioned back to solenoid injectors for newer engines. The BMW N, S, and B engine families  now exclusively use solenoid injectors, which are simpler, more reliable, and cost-effective . Other manufacturers followed suit, favoring the proven performance of solenoid systems. Are Piezo Injectors Completely Gone? Not entirely. Piezo injectors still have a place in certain diesel engines , where their benefits can be fully realized without the drawbacks that plagued their use in gasoline engines. Diesel engines operate at higher fuel pressures and cooler temperatures , making them better suited to piezo injectors . However, even in diesel applications, some manufacturers are returning to solenoid systems  due to cost and longevity concerns. Lessons from the Piezo Injector Experiment The journey of piezo injectors highlights the challenges of pushing technological boundaries . While their introduction marked a leap forward in fuel injection precision and performance , their real-world implementation emphasized the importance of practicality and reliability . Advanced technology isn’t always the best choice if it comes at the expense of durability, cost, and ease of service . The Future of Fuel Injection Systems Today, most modern engines rely on evolved solenoid injectors , which now offer improved precision, faster response times, and the ability to operate at much higher fuel pressures  than earlier models. Combined with advancements in engine management systems , solenoid injectors can match or even surpass  the performance of piezo injectors without the associated drawbacks. So, the next time you pop the hood of a modern car, take a moment to appreciate fuel injectors working tirelessly  to keep the engine running smoothly. While piezo injectors may have faded from gasoline engines, their story serves as a reminder of the delicate balance between innovation and practicality  in the automotive world.
