Should You Upgrade to a Bigger Engine in 2025? An Expert’s Perspective
Navigating the automotive landscape in 2025 presents a fascinating paradox for car
buyers. With unprecedented advancements in powertrain technology, the classic dilemma of “bigger engine equals more power” is both truer and more nuanced than ever before. As someone who has spent the last decade immersed in the intricacies of automotive engineering, performance metrics, and the ever-evolving market, I’ve witnessed firsthand the shifts that make this decision more complex—and more critical—for consumers today. When you’re buying a car in the current climate, understanding engine choices isn’t just about horsepower; it’s about a holistic evaluation of performance, long-term costs, and evolving ownership experiences.
The conventional wisdom that a bigger engine inherently means higher horsepower still largely holds, especially when comparing naturally aspirated variants within the same vehicle lineage. However, 2025’s market introduces a plethora of highly sophisticated turbocharged 4-cylinder and 6-cylinder configurations that deliver astounding performance while often boasting superior fuel efficiency compared to their naturally aspirated predecessors. This blurring of lines means that simply looking at displacement numbers can be misleading. The question isn’t just about size, but about technology and optimization. Should you upgrade to the more potent option offered? Let’s dissect the benefits and drawbacks of opting for that higher-horsepower, often larger, engine, helping you make an informed decision on your next automotive investment.
The Irresistible Allure of More Power and Driving Thrills
There’s an undeniable, visceral appeal to high performance engines. The surge of acceleration, the responsiveness of the throttle, and the confidence to overtake effortlessly are fundamental aspects of a truly engaging dynamic driving experience. Historically, the larger engine option in a vehicle’s lineup has consistently translated to superior power output, and in 2025, that often still means more thrills behind the wheel. When we talk about luxury performance cars or sports car performance metrics, raw power remains a key differentiator.
Consider contemporary examples, such as the 2026 BMW 5 Series. The German automaker offers compelling choices for discerning drivers. The base 530i, equipped with its 2.0-liter TwinPower Turbo 4-cylinder, delivers a respectable 255 hp, pushing the car from zero to 60 MPH in approximately 5.9 seconds. For many, this is more than adequate for daily driving and provides a pleasant, refined experience. However, stepping up to the 540i xDrive means embracing a 3.0-liter TwinPower Turbo 6-cylinder engine, unleashing 375 hp and slashing the 0-60 MPH time to a brisk 4.4 seconds. This isn’t just a marginal improvement; it’s a significant leap in acceleration benchmarks and overall driver engagement. For enthusiasts seeking that extra punch, that effortless surge on the highway, or the sheer joy of rapid acceleration, the premium sedan power of the 540i xDrive becomes exceptionally tempting.
Similarly, within the more rugged, family-oriented segment, the 2026 Ford Explorer demonstrates this same dynamic. The popular SUV offers a robust 2.3-liter turbo 4-cylinder delivering 300 hp, which is a strong performer for a vehicle of its size, achieving an estimated 0-60 MPH in 6.0 seconds. Yet, the optional 3.0-liter turbo V6, standard in the ST trim and optional elsewhere, boosts output to a formidable 400 hp, dropping the 0-60 MPH time to an estimated 5.2 seconds. This makes a noticeable difference, especially when merging onto busy freeways, towing, or simply wanting a more assertive response from a family SUV performance vehicle. The distinction between turbocharged 4 cylinder performance and V6 engine technology is less about inherent superiority and more about the specific power delivery and emotional connection they forge with the driver. For certain segments, especially luxury performance SUVs, this upgrade is often seen as integral to the desired ownership experience.
It’s crucial to understand that horsepower vs torque plays a significant role here. While horsepower dictates top speed and overall “oomph,” torque is what you feel off the line and in the mid-range—the shove that pushes you back into your seat. Many modern, smaller displacement turbocharged engines excel at delivering strong low-end torque, giving a surprisingly punchy feel, but the larger, often multi-cylinder, turbocharged engines frequently offer a more expansive power band and sustained high-end thrust.
The Financial Reality: More Power, More Price
As satisfying as that extra horsepower can be, it’s rarely a free upgrade. One of the most significant factors influencing your decision will be the immediate financial outlay. Opting for the more powerful engine typically means a substantial increase in the vehicle’s base price, reflecting the advanced engineering, higher-grade components, and often, the inclusion of additional performance-oriented features that come bundled with the engine upgrade. When creating a car buying guide 2025, understanding these cost differentials is paramount.
Let’s revisit our examples from the 2026 model year, including factory-to-dealer delivery fees:
For the 2026 BMW 5 Series:
530i (2.0L 4-cyl): $61,075
530i xDrive (2.0L 4-cyl AWD): $63,375
540i xDrive (3.0L 6-cyl AWD): $68,275
The jump from the 530i xDrive to the 540i xDrive represents an increase of approximately $4,900. While this might seem modest in the context of a luxury vehicle, it’s a direct cost for enhanced premium sedan power.
For the 2026 Ford Explorer:
Active (2.3L 4-cyl): $40,025
ST-Line (2.3L 4-cyl): $46,715
Tremor (2.3L 4-cyl): $50,025
Tremor (3.0L V6): $54,757 (estimated)
Platinum (2.3L 4-cyl): $52,525
Platinum (3.0L V6): $57,250 (estimated)
ST (3.0L V6): $56,465
Here, the premium for the V6 engine in comparable trims can range from roughly $4,700 to $5,000. These figures are crucial for any performance car budget. This upfront cost isn’t just about the engine itself; it often reflects a higher trim level that includes other features like larger wheels, upgraded braking systems, or specific exterior/interior styling cues that reinforce the performance theme. Evaluating the upgrade package value means looking beyond just the engine.
Furthermore, higher-performance models often fall into higher insurance risk categories. This translates to increased insurance costs for high horsepower cars. It’s a hidden cost that can add hundreds, if not thousands, to your annual car ownership costs. This is an area frequently overlooked by eager buyers but critical for smart car buying strategies.
The Long-Term Impact: Fuel Economy and Ownership Costs
The financial implications of opting for a bigger engine extend far beyond the showroom. The “ugly truth,” as it’s often called, is that you’ll continue to spend more money at the pump, day after day, for the lifespan of the vehicle. In 2025, with fluctuating fuel prices and an increasing societal focus on sustainability, fuel economy optimization is a major factor for many. The laws of physics largely remain: more power often demands more fuel.
Let’s look at the latest available 2025 EPA-estimated fuel economy numbers for our examples:
BMW 5 Series:
530i (RWD): 28/35/31 MPG (City/Highway/Combined)
530i xDrive (AWD): 27/35/30 MPG
540i xDrive (AWD): 26/33/28 MPG
The difference between the 530i xDrive and 540i xDrive is a noticeable 2 MPG combined. Over years of ownership, especially with premium fuel requirements often associated with high performance engines, this translates into significant additional expenditure. For example, driving 15,000 miles a year at current fuel prices could easily add several hundred dollars annually to your operating costs.
Ford Explorer:
4-cylinder (FWD/RWD trims): 20/29/24 MPG
V6 (AWD trims): 18/25/21 MPG
The Explorer’s V6 option, while delivering exhilarating performance, also comes with a notable penalty at the pump, particularly in combined driving. This 3 MPG combined difference over the 4-cylinder model will add up significantly, impacting your overall long-term car investment.
Beyond fuel, maintenance costs high performance vehicles can also be a factor. While modern engines are incredibly durable, the increased stresses on a higher-output engine, especially one that is frequently driven enthusiastically, can potentially lead to higher wear on components like brakes, tires, and even transmission fluids. While not universally true for all upgrades, it’s a consideration, especially for specialized high performance engines.
Another consideration in 2025 is the emerging landscape of electric vehicles. While this article focuses on internal combustion engines, the conversation around “performance” increasingly includes the instant torque and silent acceleration of EVs. When evaluating overall ownership costs and long-term trends, the electric vehicle acceleration versus gasoline performance debate factors into the broader context of automotive innovation 2025. Many high CPC keywords like “hybrid powertrain efficiency” also reflect this growing trend of balancing power with environmental and economic consciousness.
Beyond the Numbers: Real-World Usability and Resale Value
An experienced hand will tell you that understanding car specifications goes beyond raw numbers. How much of that extra power can you actually use in daily driving? Unless you’re frequently engaging in track days or living in an area with unrestricted highways, the incremental benefits of, say, a 400 hp engine over a 300 hp engine might be marginal in typical stop-and-go traffic. The sheer instant torque of many modern turbocharged engine benefits means even a smaller, well-engineered engine can feel exceptionally sprightly and responsive for everyday tasks. For many, the base engine provides ample power for merging, passing, and accelerating confidently without needing to constantly tap into the full potential of a larger, thirstier counterpart. This brings us to the core of the debate: what are your priorities? Are you truly in search of ultimate sports car performance metrics, or is competent, refined power sufficient for your needs?
Furthermore, consider resale value performance models. While a performance-oriented trim might initially command a higher price, its depreciation curve can sometimes be steeper than more economical counterparts. Demand for high-performance vehicles, while strong, can also be more niche. Conversely, a vehicle with a notoriously weak or underpowered base engine might also suffer on the used car market. The sweet spot is often an engine that balances adequate power with reasonable efficiency and reliability. The goal is a sound vehicle depreciation trends strategy.
