The 2025 BMW 3-Series starts at $45,950 and remains the sport sedan benchmark, with the M340i hitting 60 mph in just 3.7 seconds during Car and Driver testing[1]. BMW simplified the lineup by dropping the 330e plug-in hybrid, leaving two distinct choices: the 255-hp 330i for balanced daily driving or the 386-hp M340i for enthusiasts who want near-M3 performance without the price tag[2]. Updates for 2025 include the iDrive 8.5 infotainment system, revised suspension tuning, and new steering wheel designs—meaningful tweaks to a sedan that already topped its class.
What’s New for 2025
BMW made targeted improvements rather than wholesale changes. The iDrive 8.5 system brings redesigned menu layouts for quicker interactions[2]. Under the hood, the M340i gains slightly more horsepower (now 386, up from 382) along with refined 48-volt mild hybrid technology for quicker throttle response[1][2].
The biggest news? What’s gone. BMW discontinued the 330e plug-in hybrid for 2025[1]. If you wanted that 22-mile electric range for short commutes, you’ll need to look at the 2024 model year or consider the BMW i4 instead.
Visual updates include new exterior colors, redesigned wheel options, and two fresh steering wheel designs. The 330i gets a two-spoke wheel with a polygonal rim, while M340i models (and 330i M Sport) receive a flat-bottom three-spoke M wheel with a colored stripe at 12 o’clock—black on 330i M Sport, red on M340i[3]. Suspension tweaks aim to improve both comfort and handling, with Comfort drive mode now delivering lighter steering effort[1].

Performance and Driving Experience
Car and Driver called the 2025 3-Series “still king of the sports sedan hill”[1]. That’s not hyperbole. At the test track, the M340i xDrive hit 60 mph in 3.7 seconds and cleared the quarter-mile in 12.2 seconds at 112 mph[1]. The 330i xDrive ran to 60 in 5.2 seconds—quicker than BMW’s conservative 5.4-second claim[1].
Consumer Reports tested their 330i xDrive at 6.3 seconds to 60 mph, noting the four-cylinder turbo “delivers plenty of propulsion” with no turbo or transmission lag from a standstill[5]. Real-world? The 330i feels genuinely quick for a 255-hp sedan. It punches above its weight.
What the spec sheet doesn’t tell you: the 3-Series transitions seamlessly between daily driver and back-road weapon. Car and Driver praised its ability to shift “from relaxed-and-refined to sharp-and-playful”[1]. J.D. Power’s test driver found the 330i M Sport “every bit as enjoyable to drive as you expect,” with brakes that feel grabby in city traffic but perfect during spirited driving[6].
The catch? Steering feel. Every reviewer mentions it. The steering is responsive, accurate, and quick—but doesn’t deliver the tactile feedback that made older BMWs legendary[1]. Most buyers won’t notice. But if you’re coming from an E46 or E90, you might miss that connection.
And that ride quality. Edmunds calls it “a little too firm at times”[2]. The M Sport package—which dealers stock heavily—makes it firmer still. For daily comfort, consider the base suspension or add the Dynamic Handling package with adaptive dampers. One Edmunds owner praised the Adaptive M-suspension in comfort mode as striking “an excellent balance between suspension comfort and drivability”[7].
Trim Levels and Pricing
| Trim | 2025 MSRP | Key Standard Features |
|---|---|---|
| 330i | $45,950 | 255 hp, 48V mild hybrid, 18″ wheels, 12.3″ + 14.9″ curved display, sport seats, wireless CarPlay/Android Auto, HiFi 10-speaker audio |
| 330i xDrive | $47,950 | All 330i features + AWD |
| M340i | $60,200 | 386 hp, M Sport brakes/suspension/diff, 18″ M wheels, sport exhaust |
| M340i xDrive | $62,200 | M340i features + AWD |
Edmunds recommends the 330i for most buyers: “its four-cylinder packs a strong punch and this model gets all of the important technology hardware”[2]. Car and Driver agrees but suggests adding the M Sport package, Dynamic Handling package with adaptive dampers, and Premium package with head-up display[1]. That combination gets you closer to the memorable 3-Series sedans of the past.
Options add up fast. The Premium Package runs around $1,600 and brings hands-free passive entry, head-up display, and heated steering wheel[1]. The Driving Assistance Professional package adds hands-free highway driving—useful tech, but you’re paying extra for features competitors include standard[2].
A well-equipped 330i easily crosses $55,000. One YouTube reviewer tested an M340i that stickered at $67,125[8]. At that price, you’re knocking on M3 territory.
Interior and Technology
BMW’s curved display setup dominates the dashboard: a 12.3-inch digital gauge cluster paired with a 14.9-inch infotainment touchscreen under one continuous glass panel[1]. The high-resolution screens remain readable in direct sunlight, and the iDrive 8.5 interface responds quickly[1].
Standard tech includes wireless Apple CarPlay and Android Auto, in-dash navigation, SiriusXM satellite radio, and a 5G Wi-Fi hotspot[1]. Wireless smartphone charging comes standard too. Optional features include augmented-reality navigation directions projected onto the head-up display, a Harman/Kardon stereo upgrade, and BMW’s hands-free highway driving system[1].
One Edmunds owner described the interior as “lovely and expensive-feeling in a tasteful manner, featuring comfortable and supportive seats, high-grade materials on all surfaces, and very well laid-out controls”[7]. Car and Driver echoes this: “Nothing feels cheap inside the 3-series”[1].
Cargo space stands out against competitors. With 17 cubic feet, the 3-Series trunk held six carry-on suitcases in Car and Driver testing—more than both the Alfa Romeo Giulia (five) and Mercedes C-Class[1]. Fold the rear seats and you get 17 total with luggage, compared to 15 in the Giulia[1].
Fuel Economy and Real-World MPG
EPA estimates rate the rear-wheel-drive 330i at 25 city/34 highway/28 combined[1]. The M340i xDrive manages 23/32/26[1].
Here’s where it gets interesting. Car and Driver recorded 42 mpg on their 75-mph highway fuel economy loop with a rear-drive 330i—well above the 34 mpg EPA highway estimate[1]. The M340i xDrive returned 33 mpg on the same test[1]. Consumer Reports measured 29 mpg overall in mixed driving with their 330i xDrive, calling it “the most efficient offering in the luxury compact sedan class”[5].
Premium fuel required across the board. The 15.6-gallon tank delivers over 500 miles of highway range in the 330i—solid for road trips. For more on what fuel BMWs require, check our detailed guide.
Safety Features and Ratings
NHTSA awarded the 2025 BMW 3-Series a 5-star overall safety rating[9]. IIHS gave it “Good” ratings across all crashworthiness tests[10].
Standard safety equipment includes forward-collision warning and automated emergency braking[1]. That’s it. And that’s the frustrating part.
Adaptive cruise control, blind-spot monitoring, and lane-keeping assist? Optional[2]. The Parking Assistance package practically parks the car for you—but costs extra[1]. Mercedes and Genesis include much of this standard. If driver-assist tech matters, budget for the Driving Assistance packages.
Competitor Comparison
| Spec | 2025 BMW 330i | 2025 Mercedes C300 | 2025 Audi A5 | 2025 Genesis G70 |
|---|---|---|---|---|
| Base MSRP | $45,950 | $49,600 | $47,595 | $43,850 |
| Horsepower | 255 hp | 255 hp | 261 hp | 252 hp |
| 0-60 mph | 5.2 sec (tested) | 5.9 sec | ~5.5 sec | 5.9 sec |
| EPA Combined MPG | 28 mpg | 28 mpg | 30 mpg | 26 mpg |
| Trunk Space | 17 cu ft | 12.6 cu ft | 13.5 cu ft | 10.8 cu ft |
| Free Maintenance | 3 yrs/36k mi | None | 1 yr | 3 yrs/36k mi |
The Audi A5 (which replaces the A4) brings a brand-new platform and competitive tech, though the 3-Series still leads on driving dynamics[2]. The Mercedes C-Class delivers more luxury and more standard safety features but costs $3,650 more[2]. The Genesis G70 undercuts on price and offers more equipment, but both Edmunds and Car and Driver note it’s showing its age[2].
Edmunds says choosing the 3-Series “was an easy decision” years ago, but “it’s no longer the only game in town.” That said, “if you prioritize exemplary handling, we think the BMW’s price premium is warranted”[1].
Reliability and Ownership
Consumer Reports flagged concerning reliability data. Their 2025 survey shows the 3-Series “is less reliable than other cars from the same model year”[11]. Owner complaints include infotainment screen blanking issues—one owner reported the screen went blank “10-15 times when starting vehicle” and even during highway driving[11].
Kelley Blue Book owner reviews mention “high maintenance costs and issues with the suspension, steering, and exhaust noise”[12]. That’s the honest reality of BMW ownership once the warranty expires. For context on long-term ownership, see our guide on what mileage BMWs start having problems.
On the positive side, BMW’s warranty coverage competes well: four years/50,000 miles bumper-to-bumper, four years of roadside assistance, and—the real differentiator—three years/36,000 miles of complimentary scheduled maintenance[1]. Neither Mercedes nor Audi (beyond year one) matches that maintenance coverage.
Pros and Cons
What Works
- M340i xDrive hits 60 mph in 3.7 seconds—faster than BMW’s 4.1-second claim and competitive with cars costing $20k more[1]
- Real-world fuel economy beats EPA estimates by significant margins—42 mpg highway versus 34 mpg rated in Car and Driver testing[1]
- 17 cubic feet of trunk space beats every German competitor in the segment, fitting six carry-on bags without folding seats[1]
- Three years of complimentary maintenance saves hundreds versus Mercedes and Audi, which cover less or nothing[1]
What Doesn’t
- Ride quality feels firm and busy, especially with M Sport suspension—rough roads become tiresome on daily commutes[2]
- Standard safety equipment is minimal—adaptive cruise, blind-spot monitoring, and lane-keeping cost extra while competitors include them[2]
- Consumer Reports reliability scores are below average, with owners reporting infotainment screen blank-outs during driving[11]
- No more plug-in hybrid option—the 330e’s discontinuation leaves EV-curious buyers without a middle ground before the i4[1]
FAQs
Is the 2025 BMW 3-Series worth buying?
For driving enthusiasts who prioritize handling over features, yes. No competitor matches the 3-Series’ combination of chassis dynamics, powertrain refinement, and available performance. But if you want more standard safety tech for less money, the Genesis G70 deserves a test drive. And if ride comfort matters more than cornering prowess, the Mercedes C-Class trades handling sharpness for daily livability[1][2].
Should I buy the 330i or M340i?
The 330i satisfies most buyers. Its 255 hp feels quicker than the numbers suggest, Consumer Reports called it “plenty of propulsion,” and you save $14,250 over the base M340i[5]. Choose the M340i if straight-line speed matters—3.7 seconds versus 5.2 to 60 mph—or you want the sportier chassis tuning and exhaust note. Edmunds says the M340i lets you “have a lot of fun behind the wheel without having to pay M3 prices”[2].
What changed between the 2024 and 2025 BMW 3-Series?
The updates are evolutionary, not revolutionary: iDrive 8.5 software with faster menus, slightly more power for the M340i (386 hp vs 382 hp), new steering wheel designs, fresh color options, and suspension tuning that prioritizes comfort in relaxed driving modes[1]. The biggest loss? BMW dropped the 330e plug-in hybrid entirely for 2025[2].
Is the 2025 BMW 3-Series reliable?
Consumer Reports data suggests below-average reliability for the 2025 model year, with owners flagging infotainment issues and electronic glitches[11]. The B48 four-cylinder and B58 inline-six engines themselves have proven durable across BMW’s lineup. The three-year/36,000-mile complimentary maintenance helps offset ownership costs during the warranty period[1].
