Acura CSX

Acura CSX: Which Version Should You Buy?

The Acura CSX was produced from 2005 to 2011 as a Sedan across a single generation. Choosing between its three listed versions is mainly a choice among the 155 hp 2.0 MT, the 155 hp 2.0 AT, and the more powerful 197 hp 2.0 MT. All use a 1,998 cc naturally aspirated Gasoline engine, FWD, and independent spring suspension at both ends.

The Acura CSX was produced from 2005 to 2011 as a Sedan across a single generation. Choosing between its three listed versions is mainly a choice among the 155 hp 2.0 MT, the 155 hp 2.0 AT, and the more powerful 197 hp 2.0 MT. All use a 1,998 cc naturally aspirated Gasoline engine, FWD, and independent spring suspension at both ends. The 155 hp versions offer either Manual or Automatic operation, while the 197 hp 2.0 MT adds 42 hp and delivers the quickest acceleration in the range.

Acura CSX generations

The Acura CSX has one generation, so there is no between-generation mechanical progression to compare in the supplied specifications.

The 1 generation ran from 2005 to 2011 and used a Sedan body. It contains three versions: a 155 hp 2.0 MT, a 155 hp 2.0 AT, and a 197 hp 2.0 MT. No separate restyling is identified in the data. Because every version covers the same production period, a model year such as 2008 or 2009 does not by itself establish which engine and transmission specification the car has; the exact version and power output must also be checked.

Acura CSX engine specs and transmissions

Every Acura CSX engine listed here has a displacement of 1,998 cc, Gasoline fuel, 4 Inline cylinders, 4 valves per cylinder, no boost, a front transverse installation, and distributed multi-point injection. Bore and stroke are 86 × 86 in all three versions, and the specified fuel is 95.

The two 155 hp versions have identical engine output: 155 hp, 114 kW, and 188 Nm. Their compression ratio is also the same at 9.6. The meaningful choice between them is therefore the transmission: a 5-speed Manual in the 2.0 MT or a 5-speed Automatic in the 2.0 AT.

The 197 hp 2.0 MT uses a 6-speed Manual and a compression ratio of 11. It produces 42 hp and 31 kW more than either 155 hp version, an increase of about 27.1%. However, its listed torque is 49 Nm lower, and its output peaks occur higher: maximum power at 7,800 rpm rather than 6,000 rpm, and maximum torque at 6,100 rpm rather than 4,500 rpm.

Calculated from the supplied displacement and output, the 155 hp engines produce about 77.6 hp per litre. The 197 hp engine produces about 98.6 hp per litre, approximately 21.0 hp per litre more. This makes the 197 hp 2.0 MT the clear choice when power density and maximum output matter most.

Acura CSX performance and MPG

The 197 hp 2.0 MT has the quickest listed 0–100 km/h time at 8.5 seconds. It is 0.5 seconds quicker than the 155 hp 2.0 MT and 1.1 seconds quicker than the 155 hp 2.0 AT. Its 210 km/h top speed matches the Automatic and is 10 km/h higher than that of the 155 hp Manual.

The comparison between the two 155 hp cars is less straightforward. The 2.0 MT reaches 100 km/h 0.6 seconds sooner, but its stated top speed is 10 km/h lower than the 2.0 AT. Buyers prioritizing acceleration should therefore prefer the 155 hp Manual; buyers prioritizing Automatic operation do not sacrifice power or listed maximum speed.

Acura CSX MPG cannot be calculated from the supplied data. City, highway, and combined fuel consumption are all not measured for every version. CO₂ output is also not measured, so the figures cannot support an economy or emissions ranking. The 2.0 MT versions have a listed Euro 4 classification; the environmental class of the 2.0 AT is not measured.

Acura CSX dimensions, weight, tank, and wheels

Exterior dimensions are not measured in the supplied data. Ground clearance and wheel sizes are also not measured for any version.

The 155 hp 2.0 MT and 155 hp 2.0 AT have the same 1,290 kg kerb weight and 1,740 kg gross weight. The 197 hp 2.0 MT weighs 1,292 kg at the kerb, only 2 kg more, while its listed gross weight is 210 kg lower at 1,530 kg. All three versions have a 50 L fuel tank.

Based on kerb weight and horsepower, either 155 hp version carries about 8.32 kg per hp. The 197 hp 2.0 MT carries about 6.56 kg per hp, an advantage of approximately 1.76 kg per hp. Put another way, the more powerful Manual gains 42 hp while adding only 2 kg of kerb weight, which closely matches its better acceleration result.

Both front and rear suspension are Independent, spring on every version. Each version also has Ventilated disc front brakes and Disc rear brakes, so the supplied chassis specifications do not create an obvious reason to choose one transmission or power output over another.

Which Acura CSX version should you buy?

Choose the 197 hp 2.0 MT if performance is the priority. It combines the highest output, the best power per litre, the lowest weight-per-horsepower figure, a 6-speed Manual, the quickest 0–100 km/h time, and the joint-highest top speed. Compared with either 155 hp version, its extra 42 hp costs only 2 kg in kerb weight. No price data is supplied, however, so it is impossible to say whether any additional purchase cost is justified.

Choose the 155 hp 2.0 MT if you want a Manual but do not need the maximum-output engine. It has 188 Nm—49 Nm more than the 197 hp version—and that maximum occurs at 4,500 rpm rather than 6,100 rpm. It also reaches 100 km/h 0.6 seconds sooner than the equally powerful Automatic. Its compromises are a 5-speed rather than 6-speed Manual, 42 hp less power, and a 200 km/h rather than 210 km/h top speed.

Choose the 155 hp 2.0 AT when an Automatic transmission is the deciding requirement. It retains the same 155 hp, 188 Nm, 1,290 kg kerb weight, and 50 L tank as the corresponding Manual, while matching the 197 hp model’s 210 km/h top speed. Its 9.6-second 0–100 km/h result is the slowest of the three, and no consumption figures are available to show whether it offers an economy advantage.

For shoppers searching for an Acura CSX manual, the supplied specifications support two distinct choices with the same exact version name: the 155 hp 2.0 MT and the 197 hp 2.0 MT. The 155 hp car is the torque-heavier lower-output option; the 197 hp car is the faster, more power-dense option. There is no supplied evidence about prices, reliability, engine oil, engine codes, interior space, trunk capacity, or cars for sale, so those factors cannot be used to rank the versions here.
