Daimler X300: Which Version Should You Choose?
The Daimler X300 was offered as a Sedan from 1993 to 1997 in one generation and five listed versions. The main choice is between the 4.0-litre Inline 6 engine and the 6.0-litre V-shaped 12-cylinder engine, followed by a choice of Manual or Automatic transmission. Among versions with measured performance, the 326 hp 4.0 AT is the quickest and fastest, reaching 100 km/h in 6.3 seconds and 250 km/h.

Among versions with measured performance, the 326 hp 4.0 AT is the quickest and fastest, reaching 100 km/h in 6.3 seconds and 250 km/h. The 241 hp 4.0 MT is the quickest naturally aspirated 4.0-litre option at 7.4 seconds, while the comparable 4.0 AT takes 8.2 seconds. The 6.0 MT and 6.0 AT offer 318 hp, but their acceleration, top speed, torque, and weight were not measured, so the supplied data cannot establish that either is quicker than the 326 hp 4.0 AT.
Daimler X300 generation and version range
The Daimler X300 has one listed generation, produced from 1993 to 1997 exclusively as a Sedan. This generation contains five versions: a naturally aspirated 241 hp 4.0 AT, a naturally aspirated 241 hp 4.0 MT, a compressor-equipped 326 hp 4.0 AT, a 318 hp 6.0 MT, and a 318 hp 6.0 AT. Because there is only one generation in the data, there are no generation-to-generation changes to compare.
All five versions use Gasoline engines, RWD, independent spring suspension at the front and rear, and ventilated disc brakes at both ends. They also share 130 mm of ground clearance and an 80-litre fuel tank. The major differences therefore concern engine output, cylinder arrangement, boost, transmission, measured performance, and—where figures are available—weight.
Daimler X300 engine and specs comparison
| Version | Power | Torque | Displacement | Fuel | Cylinders | Layout | Boost | Gearbox | Drive |
|---|---|---|---|---|---|---|---|---|---|
| 4.0 AT (241 hp) | 241 hp / 177 kW at 4800 rpm | 375 Nm at 4000 rpm | 3980 cc | Gasoline, 95 | 6 | Inline | No | 4-speed Automatic | RWD |
| 4.0 MT | 241 hp / 177 kW at 4800 rpm | 375 Nm at 4000 rpm | 3980 cc | Gasoline, 95 | 6 | Inline | No | 5-speed Manual | RWD |
| 4.0 AT (326 hp) | 326 hp / 240 kW at 5000 rpm | 512 Nm at 3050 rpm | 3980 cc | Gasoline, 95 | 6 | Inline | Compressor | 4-speed Automatic | RWD |
| 6.0 MT | 318 hp / 234 kW; power rpm not measured | Torque not measured | 6000 cc | Gasoline; fuel grade not measured | 12 | V-shaped | No | 5-speed Manual | RWD |
| 6.0 AT | 318 hp / 234 kW; power rpm not measured | Torque not measured | 6000 cc | Gasoline; fuel grade not measured | 12 | V-shaped | No | 4-speed Automatic | RWD |
The naturally aspirated 4.0 AT and 4.0 MT have identical engine figures: 241 hp, 177 kW, and 375 Nm. Their calculated specific output is approximately 60.6 hp per litre. Choosing between them is therefore primarily a transmission and performance decision rather than an engine-output decision.
The compressor-equipped 4.0 AT produces 326 hp and 512 Nm from the same 3980 cc displacement. Compared with either naturally aspirated 4.0-litre version, it adds 85 hp and 137 Nm. Its calculated specific output is approximately 81.9 hp per litre, about 21.3 hp per litre more than the 241 hp engine.
The 6.0 MT and 6.0 AT each produce 318 hp from 6000 cc, or 53 hp per litre. They have 8 hp less than the compressor-equipped 4.0 AT despite using 2020 cc more displacement. Their torque figures were not measured, so a numerical torque comparison with either 4.0-litre engine is not possible.
Daimler X300 performance, acceleration, top speed, and economy
| Version | 0–100 km/h | Top speed | City consumption | Highway consumption | Combined consumption |
|---|---|---|---|---|---|
| 4.0 AT (241 hp) | 8.2 s | 232 km/h | Not measured | Not measured | Not measured |
| 4.0 MT | 7.4 s | 232 km/h | Not measured | Not measured | Not measured |
| 4.0 AT (326 hp) | 6.3 s | 250 km/h | Not measured | Not measured | Not measured |
| 6.0 MT | Not measured | Not measured | Not measured | Not measured | Not measured |
| 6.0 AT | Not measured | Not measured | Not measured | Not measured | Not measured |
Between the two 241 hp versions, the 4.0 MT reaches 100 km/h 0.8 seconds sooner than the 4.0 AT, although both have the same 232 km/h top speed. This makes the 4.0 MT the stronger performance choice when the naturally aspirated 4.0-litre engine is preferred.
The compressor-equipped 4.0 AT reaches 100 km/h in 6.3 seconds. It is 1.1 seconds quicker than the 4.0 MT and 1.9 seconds quicker than the naturally aspirated 4.0 AT. Its 250 km/h top speed is also 18 km/h higher than the two 241 hp versions.
Acceleration and top-speed figures for the 6.0 MT and 6.0 AT were not measured. Fuel consumption was not measured for any version, so no city, highway, combined, or mpg-based economy ranking can be made from the supplied data. CO₂ output and environmental class were also not measured for every version.
Daimler X300 dimensions, weight, and practical specifications
The supplied data does not include exterior length, width, height, or wheelbase. Wheel sizes were not measured for any Daimler X300 version.
| Version | Kerb weight | Gross weight | Ground clearance | Fuel tank | Wheel sizes |
|---|---|---|---|---|---|
| 4.0 AT (241 hp) | 1800 kg | 2220 kg | 130 mm | 80 litres | Not measured |
| 4.0 MT | 1800 kg | 2220 kg | 130 mm | 80 litres | Not measured |
| 4.0 AT (326 hp) | 1875 kg | 2295 kg | 130 mm | 80 litres | Not measured |
| 6.0 MT | Not measured | Not measured | 130 mm | 80 litres | Not measured |
| 6.0 AT | Not measured | Not measured | 130 mm | 80 litres | Not measured |
The two naturally aspirated 4.0-litre versions each weigh 1800 kg and carry a gross-weight rating of 2220 kg. That produces a calculated kerb-weight-to-power ratio of approximately 7.47 kg per hp.
The compressor-equipped 4.0 AT is 75 kg heavier at 1875 kg, with its gross weight likewise 75 kg higher at 2295 kg. Its additional 85 hp more than offsets that weight increase, giving a calculated ratio of approximately 5.75 kg per hp. Compared with the 241 hp versions, it carries approximately 1.72 fewer kilograms for each horsepower.
Kerb and gross weights for the 6.0 MT and 6.0 AT were not measured. Their weight-to-power ratios therefore cannot be calculated honestly from the available figures.
Daimler X300 reliability and problems
Reliability records, fault rates, service requirements, repair costs, and model-specific problems are not included in the supplied data. None of the five versions can therefore be ranked for reliability. The engine and performance figures show what distinguishes the versions technically, but they do not prove that one engine, gearbox, or boost system is more durable than another.
Which Daimler X300 version should you buy?
For the strongest verified performance, choose the 4.0 AT with 326 hp. It combines the highest output, the highest measured torque, the quickest measured 0–100 km/h time, and the highest measured top speed. Compared with the 241 hp 4.0 AT, it brings 85 additional hp, 137 additional Nm, a 1.9-second reduction in acceleration time, and an 18 km/h increase in top speed, while adding 75 kg of kerb weight.
For a naturally aspirated engine with the better measured acceleration result, choose the 4.0 MT. It has exactly the same 241 hp and 375 Nm as the naturally aspirated 4.0 AT, yet reaches 100 km/h 0.8 seconds sooner. It also provides a 5-speed Manual gearbox instead of a 4-speed Automatic.
Choose the 241 hp 4.0 AT if the 4-speed Automatic is the deciding requirement and the additional output of the compressor-equipped version is unnecessary. Its measured acceleration is the slowest of the three versions with complete performance data, but its top speed matches the 4.0 MT at 232 km/h.
The 6.0 MT and 6.0 AT are the choices for buyers specifically prioritizing the 6000 cc, 12-cylinder, V-shaped configuration. Both deliver 318 hp, with the transmission being the documented distinction: the 6.0 MT has a 5-speed Manual, while the 6.0 AT has a 4-speed Automatic. However, their torque, acceleration, top speed, and weights were not measured. On the evidence available, neither can be shown to outperform the 326 hp 4.0 AT.
No price data is provided, so the extra purchase cost of any version—and what that extra money buys in financial terms—cannot be assessed. Based strictly on the measured specifications, the 326 hp 4.0 AT is the clearest performance choice, the 4.0 MT is the quicker naturally aspirated choice, and the two 6.0-litre versions are configuration-led choices whose performance advantage is not established by the available data.
