BMW Z3

Which BMW Z3 Version Should You Buy?

The BMW Z3 choice depends chiefly on whether you value lower fuel consumption, stronger acceleration or an Automatic gearbox. In the supplied Coupe catalogue, the first generation runs from March 1996 to January 2000 with 10 listed modifications, followed by a restyling from January 2000 to December 2002 with 11 listed modifications. Every version is Gasoline and RWD.

The BMW Z3 choice depends chiefly on whether you value lower fuel consumption, stronger acceleration or an Automatic gearbox. In the supplied Coupe catalogue, the first generation runs from March 1996 to January 2000 with 10 listed modifications, followed by a restyling from January 2000 to December 2002 with 11 listed modifications. Every version is Gasoline and RWD. The 1.9 MT with 118 hp is the economy-focused option at 7.8–7.9 l/100 km combined, while the restyled 3.0 MT is the performance leader with 231 hp, 300 Nm, 0–100 km/h in 6 seconds and a 250 km/h maximum speed. Buyers wanting a middle ground should compare the 2.2 MT, 2.5 MT and earlier 2.8 MT versions.

BMW Z3 generations and version changes

The original BMW Z3 generation covers March 1996 through January 2000 and is listed as a Coupe with 10 modifications. Its engine sizes extend from 1798 cm³ in the 1.8 MT to 2798 cm³ in one 2.8 AT entry. Outputs range from 115 hp to 193 hp, and both Manual and Automatic transmissions appear. The Automatic versions use 4 gears, while every listed Manual has 5 gears.

The restyled first generation covers January 2000 through December 2002 and is also listed as a Coupe, now with 11 modifications. It retains 1.9 MT and 2.0 MT choices while adding 2.2 MT, 2.2 AT, 2.5 MT, 2.5 AT, 3.0 MT and 3.0 AT entries. Every listed transmission has 5 gears. The highest output rises from 193 hp in the original generation to 231 hp after restyling, an increase of 38 hp. The best listed 0–100 km/h time improves from 6.9 seconds to 6 seconds, while the highest maximum speed rises from 229 km/h to 250 km/h.

BMW Z3 engine options and specs

Repeated names below are distinguished by output or other database specifications. This matters particularly for the two original-generation 2.8 MT entries, the two original 2.8 AT entries and the two restyled 2.0 MT records.

All listed engines use distributed injection (multi-point). Calculated from displacement and output, the 118 hp 1.9 MT produces about 62.3 hp per litre, the 170 hp 2.2 versions about 78.3 hp per litre, the 187 hp 2.5 versions about 75.0 hp per litre and the 231 hp 3.0 versions about 77.5 hp per litre. The original 140 hp 1.9 versions reach about 73.9 hp per litre. These ratios provide a direct comparison of catalogue output relative to engine capacity; they are not additional measured specifications.

BMW Z3 performance, fuel consumption and mpg comparison

For the original 140 hp 1.9 pair, choosing the 1.9 MT rather than the 1.9 AT cuts the listed 0–100 km/h time by 1 second and raises maximum speed by 9 km/h, although Manual fuel consumption is not measured. Among the restyled 2.2 versions, the 2.2 MT is 1 second quicker to 100 km/h, 4 km/h faster and uses 0.4 l/100 km less combined than the 2.2 AT.

The restyled 3.0 MT is 0.3 second quicker to 100 km/h than the 3.0 AT, has an 8 km/h higher maximum speed and consumes 0.7 l/100 km less combined. Against the 118 hp 1.9 MT, it provides 113 hp and 120 Nm more, reaches 100 km/h 4.4 seconds sooner and adds 54 km/h to maximum speed, while requiring 1.6–1.7 l/100 km more combined.

BMW Z3 dimensions, weight and capacity

External length, width, height and wheelbase are not measured in the supplied data. Wheel sizes are also not measured for every version, so no catalogue-based wheel-size comparison is possible. All versions have 110 mm of ground clearance and a 51-liter fuel tank.

Kerb weights in the original generation range from 1160 kg for the 1.8 MT to 1310 kg for the 2.0 AT among versions with measurements. Gross weights run from 1410 kg for the 1.8 MT to 1580 kg for the 2.0 AT. The original 2.8 AT with 192 hp has a kerb weight that is not measured, while its gross weight is 1570 kg.

For the restyled generation, measured kerb weights range from 1220 kg for either 118 hp 1.9 MT record to 1345 kg for the 2.2 MT. Gross weights range from 1490 kg for the 1.9 MT to 1575 kg for the 3.0 versions. Kerb weight is not measured for the 2.2 AT and 3.0 AT.

Calculated weight-to-power figures sharpen the buying comparison. The original 1.8 MT carries about 10.1 kg per hp, the original 118 hp 1.9 MT about 10.3 kg per hp, and the original 193 hp 2.8 MT about 6.5 kg per hp. In the restyled range, the 2.2 MT is about 7.9 kg per hp, the 2.5 MT and 2.5 AT are about 6.8 kg per hp, and either measured 3.0 MT is about 5.6 kg per hp. Weight distribution and weight-reduction results are not measured.

Which BMW Z3 version to choose

Choose the 1.9 MT with 118 hp if measured fuel economy is the priority. Its 7.8–7.9 l/100 km combined figures are the lowest in the data, and its 1220 kg kerb weight is also at the low end of the measured range. The trade-off is performance: 0–100 km/h takes 10.4 seconds and maximum speed is 196 km/h.

Choose the original 1.9 MT with 140 hp if you want more output from the same 1895 cm³ displacement without moving to a six-cylinder version. It adds 22 hp over the 118 hp 1.9 MT and cuts 0–100 km/h time by 0.9 second, but its fuel consumption is not measured. The 1.9 AT preserves the 140 hp and 180 Nm ratings but is slower and heavier: its measured kerb weight is 1225 kg, 40 kg above the 1.9 MT with 140 hp.

Choose the restyled 2.2 MT for the strongest documented balance of six-cylinder output, acceleration and measured economy. It has 170 hp, reaches 100 km/h in 7.9 seconds and returns 9.2 l/100 km combined. Compared with the restyled 2.0 MT with 190 Nm, it adds 20 hp and 20 Nm, cuts the acceleration time by 1.1 seconds and reduces combined consumption by 0.7 l/100 km, although its measured kerb weight is 75 kg higher.

Choose the 2.5 MT or 2.5 AT if 187 hp, 237 Nm, 7.5-second acceleration and a 225 km/h maximum speed meet your target. Their performance figures and measured 1270 kg kerb weights are identical, so the catalogue data gives no performance penalty for choosing Automatic. Fuel consumption for both is not measured.

Choose the restyled 3.0 MT for maximum performance. It combines 231 hp and 300 Nm with the best 0–100 km/h time and maximum speed in the supplied data. At 1305 kg, it has the best calculated weight-to-power result among versions with measured kerb weight. Choose the 3.0 AT only when Automatic operation matters more than the Manual model’s 0.3-second acceleration advantage, 8 km/h speed advantage and 0.7 l/100 km combined-consumption advantage.

The data contains no prices, sale listings, reliability results, problem records, repair histories or engine-swap information. Consequently, “extra money” cannot be quantified and no version can be ranked by purchase price or reliability. On measurable catalogue specifications alone, the 1.9 MT with 118 hp is the economy choice, the 2.2 MT is the balanced choice, and the 3.0 MT is the performance choice.
