BMW Z3 Vs Z4: Which One Is the Worth Investment?

Blessed with a loyal fanbase, BMW has never failed to deliver on its impactful legacy. BMW Z3 and Z4 are two legendary releases from BMW in the last decade. 

The Z3 is the first released convertible modern roadster, preceding the BMW Z4.  Furthermore, the Z3 has a traditional look, whereas the Z4 is more stylish. Their price also varies because of higher horsepower and more comfort features. 

Some other dynamics at play make these two cars separate from each other. But it mostly comes down to your preferences. Both of these cars are stellar in both looks and performance. So, hop on as we explore their differences further!

BMW Z3 Overview

The first thing that comes to mind when talking about the BMW Z3 is “humble”. It is the predecessor of the Z4, rocking a more traditional and petite attire. 

This car rocks six cylinders and can provide a silky smooth riding experience on the right tracks. The combination of price and such performance is hard to come by in today’s market. 

Furthermore, the Z3 got its trademark features from one of the earliest releases from BMW, the Z1. The main inspiration that drove the release of the Z3 was BMW’s classic, the 507 roadsters. The Z3 inherited the 507’s bottle shape from the front to the rear. 

It also includes gill-shaped vents. These vents carried the BMW roundel. This tradition continued till the release of the second generation Z4. But on the latest releases, this was abandoned. 

When it comes to performance, the Z3 has a larger engine capacity compared to the Z2. And because of the six-cylinder build, it also boosts increased engine stability. 

Having more cylinders means shorter breaks between strokes. This makes the engine perform more efficiently.
