What Size Is a BMW 328i?

The BMW 328i is a compact executive sedan (or wagon in some years) with dimensions that typically measure around 182–183 inches (about 4.62–4.66 meters) in length, 71–72 inches (about 1.80–1.82 meters) in width, and 55–57 inches (about 1.41–1.45 meters) in height, depending on the generation and body style. These measurements place it firmly in the compact luxury segment, offering a balance between city-friendly size and usable interior space.

Understanding the BMW 328i: Model Context

The BMW 328i designation has been used across several generations of the 3 Series, primarily in the E36, E46, E90/E91, and F30/F31 ranges. Although its engine and technology have changed, its fundamental role has remained the same: a compact premium car that is smaller than a midsize sedan but larger and more comfortable than a typical economy compact.

Key Dimensions by Generation

The exact size of a BMW 328i depends on the generation and body style. Below is a breakdown of the most common modern 328i models and their approximate dimensions to clarify how the car has grown over time.

F30/F31 3 Series (2012–2018): The Best-Known Modern 328i

For most current shoppers and owners, “328i” usually refers to the F30 (sedan) or F31 (wagon) sold in markets worldwide from model years 2012 to 2015/2016 (in some regions through 2018). This is one of the most common versions on the road today.

The following list summarizes the typical exterior dimensions of the F30 328i sedan, which most people mean when they ask about the size of a BMW 328i.

• Body style: 4-door sedan (F30) or 5-door wagon/touring (F31)
• Overall length: approx. 182.0–182.5 in (about 4,623–4,635 mm)
• Overall width (without mirrors): approx. 71.3 in (about 1,811 mm)
• Overall width (with mirrors): approx. 79.1 in (about 2,009 mm)
• Height: approx. 56.3 in (about 1,430 mm)
• Wheelbase: approx. 110.6 in (about 2,810 mm)
• Front track: approx. 60.3–60.8 in (about 1,531–1,545 mm)
• Rear track: approx. 61.3–62.0 in (about 1,557–1,575 mm)
• Curb weight (varies by spec): roughly 3,300–3,600 lb (about 1,497–1,633 kg)

These measurements make the F30 328i slightly larger than earlier 3 Series generations, with more legroom and trunk space, while staying compact enough for tight city parking and agile handling.

E90/E91 3 Series (2005–2013): The Previous Generation 328i

The E90 (sedan) and E91 (wagon) 328i models are smaller than the F30 but still fall in the compact executive category. They are often cross-shopped in the used market, so their size is relevant for comparison.

The following list details the approximate exterior dimensions of the E90 328i sedan.

• Body style: 4-door sedan (E90) or 5-door wagon/touring (E91)
• Overall length: approx. 178.2 in (about 4,527 mm)
• Overall width (without mirrors): approx. 71.5 in (about 1,815 mm)
• Height: approx. 55.9 in (about 1,420 mm)
• Wheelbase: approx. 108.7 in (about 2,760 mm)
• Curb weight (varies by spec): roughly 3,300–3,500 lb (about 1,497–1,588 kg)

Compared to the F30, the E90 328i is a little shorter and has a slightly shorter wheelbase, which translates to marginally less rear-seat space, though both generations occupy a similar footprint on the road.

Older Generations: E36 and E46 328i

Earlier eras of the 328i—particularly the E36 (mid‑1990s, mostly outside the U.S.) and E46 (late‑1990s to mid‑2000s)—were notably smaller than modern models. Enthusiasts often describe them as more compact and lighter, with tighter interior space but excellent maneuverability.

The following list outlines approximate sizes of the E46 3 Series 328i/330i sedan, which is a useful reference for how much the car has grown over the decades.

• Body style: 4-door sedan, 2-door coupe, convertible, wagon (market-dependent)
• Overall length (sedan): approx. 176.0–176.7 in (about 4,470–4,490 mm)
• Overall width: approx. 69.2 in (about 1,758 mm)
• Height: approx. 54.0–55.7 in (about 1,372–1,415 mm)
• Wheelbase: approx. 107.3 in (about 2,730 mm)
• Curb weight: roughly 3,100–3,400 lb (about 1,406–1,542 kg), depending on trim and equipment

These dimensions show that earlier 328i models were shorter and narrower, giving them a distinctly smaller footprint compared with the more modern F30 generation.

Interior Space and Practicality

Beyond exterior measurements, the size of a BMW 328i is also defined by how much room it offers for passengers and cargo. Modern 328i models are designed to comfortably fit four adults and, in many cases, a fifth in the rear middle seat for shorter trips.

The following list summarizes typical interior and cargo space characteristics, focusing on the F30 328i, which is a representative modern version.

• Seating capacity: 5 passengers (2 front, 3 rear)
• Front headroom: approx. 40–41 in (about 1,016–1,041 mm)
• Front legroom: approx. 42–42.1 in (about 1,067 mm)
• Rear legroom: approx. 35–35.1 in (about 889 mm)
• Rear headroom: approx. 37–38 in (about 939–965 mm), slightly less with sunroof
• Trunk volume (sedan): roughly 13.0–13.7 cubic feet (about 368–388 liters)
• Cargo volume (wagon): significantly larger, with rear seats up or folded, depending on configuration

In practical terms, this makes the 328i suitable as a daily family car for many buyers, while still remaining compact enough to feel nimble in dense urban traffic and tight parking spaces.

How the 328i Compares in Size to Other Segments

To better understand the 328i’s size, it helps to compare it to other common car categories. This places the BMW 328i firmly in context as a compact luxury sedan rather than a small city car or a full-size family sedan.

The following list compares the BMW 328i (F30) with typical car segments, using approximate dimensions for reference.

• Versus compact economy cars (e.g., Honda Civic, Toyota Corolla): The 328i is similar in length or slightly longer, but generally wider, with a more substantial stance and more rear-wheel-drive–oriented proportions.
• Versus mainstream midsize sedans (e.g., Honda Accord, Toyota Camry): The 328i is usually a bit shorter in overall length, with a tighter rear seat but a more compact overall footprint.
• Versus larger luxury sedans (e.g., BMW 5 Series, Mercedes E‑Class): The 328i is clearly smaller, with less rear legroom and trunk space, reflecting its role as a step below the midsize luxury class.
• Versus compact crossovers/SUVs: The 328i is lower and often shorter, offering less cargo height but generally superior handling and a lower center of gravity.

These comparisons underscore that the BMW 328i occupies a sweet spot for drivers who want premium features and solid space without stepping up to a larger, more cumbersome vehicle.

Why the Exact Size Varies

Even within a single generation, the size of a BMW 328i can vary slightly due to trim, equipment, and regional specifications. Factors like sport suspension, M Sport body kits, different wheels, and roof rails on wagons can all affect height and overall width at a fine level of detail.

The following list explains key factors that can influence the precise measurements of a given 328i.

• Body style: Sedan vs. wagon/touring vs. coupe or convertible in older generations.
• Trim packages: M Sport or performance packages may add different bumpers or side skirts, slightly altering length and width.
• Wheel and tire setup: Wider wheels and tires can change track width and overall stance.
• Market differences: Some regions have different bumper standards or equipment that can marginally alter dimensions.
• Model year changes: Facelifts (LCIs in BMW terminology) sometimes bring subtle changes to bodywork.

While these adjustments rarely change the basic classification of the 328i as a compact executive sedan, they explain why official figures may differ slightly from one specification sheet to another.

Summary

The BMW 328i is a compact executive car whose size has gradually increased across generations but has consistently remained in the compact luxury segment. Modern versions such as the F30 sedan measure roughly 182 inches in length, 71 inches in width, and 56 inches in height, backed by a wheelbase of about 110 inches. Earlier generations like the E46 and E90 are slightly smaller but follow the same basic footprint. Overall, the 328i offers a balanced size: large enough to carry four adults and their luggage in comfort, yet compact enough to feel agile and manageable in everyday urban driving.

Is a BMW 328i a fast car?

Whether a 328i is fast depends on the model year and condition, but generally, it is considered a peppy and capable car that is not as fast as the M3 or 335i variants. For example, a 2016 328i can reach 60 mph in about 5.2 seconds, while older, less powerful versions may take around 7.4 seconds. Modern versions often have turbocharged engines with quick acceleration for daily driving, but modifications can significantly increase performance.
 
Performance by model year

• Older models (e.g., 2008): With a 230 horsepower inline-six engine, a 0-60 mph time of around 6.3 seconds was achievable. This is considered quick for its time but not in the “fast” category by today’s standards. 
• Newer turbocharged models (e.g., 2016): A 2016 328i with a turbocharged engine can reach 60 mph in approximately 5.2 seconds, which is quite fast for a non-M car. 
• Modern turbocharged models (e.g., 2014): A 2014 328i xDrive with a 2.0L turbo-four engine can accelerate to 60 mph in about 5.7 to 5.8 seconds. 

Performance considerations

• Stock vs. modified: Stock 328is are quick, but modified versions can be much faster. For example, one modified 328i reportedly reached 60 mph in around 5.6 seconds and ran the quarter-mile in 13.7 seconds. 
• Transmission: An automatic transmission can be slightly slower than a manual, but the difference can be minimal. 
• M vs. non-M models: The M3 and 335i models are significantly faster than the 328i. 
• Driving experience: While a 328i can be very fast, it is also designed as a family sedan. It may not feel as fast as a dedicated sports car, but it provides a good balance of performance and comfort for daily driving. 

How big is a BMW 328i?

The BMW 328i height measured from the ground to the top of the car is 1508 mm, the width is 1828 mm and the length is 4824 mm.

Why are used BMW 328i so cheap?

As said, they are cheap because of higher costs to repair. Generally, parts are more expensive and can be more difficult to source, being less popular (you could be off the road until they’re located and shipped).
