The 2023 BMW Z4 delivers confident handling and punchy turbocharged engines in a package refined enough for daily driving[1]. Starting at $52,800 for the sDrive30i and $65,300 for the M40i, this two-seat roadster bridges the gap between affordable sports cars and premium Porsches[2]. The key update for 2023 is the M Sport package becoming standard on the four-cylinder model, enhancing both performance and visual appeal[1].
BMW made the M Sport package standard on the sDrive30i for 2023, eliminating the need to option it separately[1]. This package includes M Sport suspension for sharper handling, an aerodynamic body kit, and an M Sport steering wheel[1]. A new 19-inch wheel design with matte black finish and diamond-polished edges is available, along with the M Shadowline lighting package featuring black headlamp inserts[1].
Three new paint colors joined the lineup: Thundernight Metallic, Portimao Blue Metallic, and Skyscraper Grey Metallic[1]. Unlike the mechanically similar Toyota GR Supra, the Z4 remains automatic-only for 2023[1]. For those exploring MSRP definitions, the Z4 pricing represents competitive positioning in the premium roadster segment.
| Trim | MSRP | As-Tested | 0-60 mph |
|---|---|---|---|

Prices include destination. Data from Car and Driver testing[1][3]
Used 2023 Z4 prices currently range from $38,257 for the sDrive30i to $51,241 for the M40i[4]. The Z4 holds its value better than most vehicles, with a 44% depreciation rate after five years compared to the 60% average[5]. Understanding BMW maintenance costs helps budget for long-term ownership.
The 2.0-liter turbocharged four-cylinder produces 255 hp and 294 lb-ft of torque[1]. Car and Driver tested it at 5.1 seconds to 60 mph—peppy but slightly slower than a Porsche 718 Boxster[1]. The Dynamic Handling package adds M Sport brakes and an M Sport differential for additional traction[1].
EPA fuel economy rates at 25 mpg city and 32 mpg highway[1]. With the 48V mild hybrid system, real-world efficiency often exceeds estimates during normal driving[6].
The turbocharged 3.0-liter inline-six delivers 382 hp and 369 lb-ft of torque[1]. This engine achieves 60 mph in just 3.5 seconds and covers the quarter-mile in 12.0 seconds at 116 mph[1]. On Car and Driver's 75-mph highway test, the M40i far exceeded its EPA rating with an impressive 37 mpg[1].
Adaptive M Sport dampers provide a versatile ride, though even in Comfort mode, the suspension favors communication over cushion[3]. The Z4 pulled 1.00 g on the skidpad during testing[1]. For those comparing BMW performance models, explore our 2023 BMW M3 review.

The Z4 may have the best interior in its class, featuring luxe materials, exceptional panel fitment, and excellent control placement[1]. Comfortable seats with sizable bolsters hold occupants firmly during spirited driving, and even drivers taller than six feet fit comfortably[1].
Standard equipment includes:
The well-insulated cloth roof seals tightly. With the top up, the interior is impressively quiet—so little wind or road noise it almost feels like a coupe[1]. The top folds in seconds with a button push, and a standard wind blocker minimizes buffeting even at high speeds[1].
Storage includes several cabin bins, a felt-lined cubby near the steering wheel, a netted shelf behind the seats, two big cupholders, and a center console compartment[1]. The 10-cubic-foot trunk accommodates luggage for a weekend road trip[1]. For BMW technology features, see when CarPlay became available.

BMW's complimentary maintenance coverage is a standout benefit not offered by the Nissan Z[1]. Learn more about BMW fuel requirements and coolant specifications.
