The BMW 3 Series remains the benchmark sport sedan — a rigid, responsive chassis paired with the refined cabin expected of a premium vehicle. For drivers across Riverside and nearby communities like Corona, Moreno Valley, and Ontario, the 3 Series balances highway efficiency with sharp, confident handling. The 2026 edition carries that legacy forward with updated technology, standard driver-assistance, and a new 48-volt mild-hybrid system on both engines.
The 2026 3 Series is offered in two core sedan models. The 330i is the well-equipped entry point, powered by a 2.0L turbocharged four-cylinder paired with an eight-speed automatic. The M340i steps up to a 3.0L turbocharged inline-six — the B58, now rated at 386 hp — with M Performance hardware. Both are rear-wheel drive as standard, with BMW’s xDrive all-wheel drive available for roughly $2,000 more.
| Trim | Starting MSRP | Engine | Drivetrain |
|---|---|---|---|
| 330i | $48,850 | 2.0L I4 turbo | RWD standard (xDrive available) |
| M340i | $63,050 | 3.0L I6 turbo | RWD standard (xDrive available) |
MSRP for new vehicles covers manufacturer/distributor equipment and logistics fees, all of which are subject to revision. It does not account for taxes, registration, dealer-installed additions, or other local charges. MSRP is not a retail advertisement; actual dealer pricing will vary. The dealer sets the final price.
The 330i focuses on a balance of agility and efficiency, returning an EPA-estimated 28 city / 35 highway / 31 combined MPG in rear-wheel-drive form. The M340i delivers a far more aggressive power curve from its inline-six while still posting a respectable 27 city / 33 highway / 29 combined MPG (RWD). Adding xDrive trims those figures slightly. Both engines run on premium unleaded.
| Trim (RWD) | City MPG | Highway MPG | Combined MPG |
|---|---|---|---|
| 330i | 28 | 35 | 31 |
| M340i | 27 | 33 | 29 |
EPA-estimated fuel economy figures are for comparison purposes only. Your actual mileage will vary depending on driving conditions, how you drive and maintain your vehicle, battery age/condition, and other factors.
Wheel options range from 18-inch dual-spoke designs on the 330i to 19-inch M dual-spoke wheels, and Adaptive M Suspension is available for real-time damping adjustments.
This generation makes several formerly optional features standard. Highlights across the 2026 lineup include:
| Feature | Availability & Detail |
|---|---|
| BMW Digital Key | Standard — lock, unlock, and start via smartphone; share with up to five people |
| Lane Departure Warning | Standard |
| Pre-Collision Safety System | Standard |
| BMW Curved Display | Standard infotainment display |
| IIHS Small Overlap Front | “Good” crash-test rating |
| Adaptive M Suspension | Available |
| Blind Spot Monitoring | Available |
| xDrive All-Wheel Drive | Available on 330i and M340i |
Yes. The 330i comes standard with rear-wheel drive and can be configured with xDrive all-wheel drive for an additional cost. xDrive distributes power between the front and rear wheels for added traction in rain or on loose surfaces.
The standard suspension is tuned for a fixed balance of comfort and sport. Adaptive M Suspension uses electronically controlled dampers that adjust stiffness in milliseconds based on road conditions and your selected driving mode.
The 3 Series is typically equipped with run-flat tires, designed to be driven a limited distance after a puncture. A space-saver spare is available as an optional add-on.
The BMW Digital Key lets you use a compatible smartphone to lock, unlock, and start the vehicle, and to share digital keys with up to five other people.
The 3 Series has performed well in safety evaluations, earning a “Good” rating from the IIHS in the small overlap front crash test. Standard features include Lane Departure Warning and a Pre-collision safety system, with Blind Spot Monitoring available.
