Hyundai XG: Which Version Should You Buy?
The Hyundai XG catalogue covers one generation of Sedan produced from October 1998 to April 2005, including a restyling introduced in July 2003. The choice ranges from the 2.4 MT with 139 hp to the restyled 3.5 AT with 197 hp. For maximum measured performance, the restyled 3.5 AT is the clear pick: it reaches 100 km/h in 8.6 seconds and 230 km/h.

For maximum measured performance, the restyled 3.5 AT is the clear pick: it reaches 100 km/h in 8.6 seconds and 230 km/h. For lower measured fuel consumption, the 2.5 AT leads with 9.8 l/100 km combined. The 2.5 MT offers a useful middle ground, combining 163 hp with a 9.1-second acceleration time and a 213 km/h top speed.
Hyundai XG generations and restyling
The first-generation Hyundai XG was offered from October 1998 through July 2003 as a Sedan with six listed versions: 2.4 MT, 2.5 AT, 2.5 MT, two 3.0 AT variants distinguished by 188 hp and 192 hp, and 3.5 AT.
The same generation was restyled for the period from July 2003 through April 2005. The restyled Sedan has four listed versions: 2.5 AT, 2.5 MT, 3.0 AT with 188 hp, and 3.5 AT with 197 hp. The 2.4 MT and the 192 hp 3.0 AT are not listed after the restyling.
For the versions that appear on both sides of the update, the 2.5 AT and 2.5 MT retain the same stated power, torque, performance, consumption, weight and transmission figures. The 188 hp 3.0 AT retains its engine output, but the restyled entry does not provide measured acceleration, top-speed or consumption figures. The 3.5 AT changes from 194 hp and 293 Nm before the restyling to 197 hp and 292 Nm afterward: that is 3 hp more and 1 Nm less.
Hyundai XG engine specs
All listed engines use Gasoline, distributed injection (multi-point) and no boost. Every version is FWD. Exact database version names are retained below; identical names are separated by output and production period.

Power per litre helps put the engine choices on equal terms. The 2.4 MT produces about 59.1 hp per litre. Both 2.5 versions produce about 65.4 hp per litre, the strongest ratio in the catalogue. The 188 hp 3.0 AT produces about 63.3 hp per litre, while the 192 hp 3.0 AT reaches about 64.6 hp per litre. The earlier 194 hp 3.5 AT delivers about 55.5 hp per litre, rising to about 56.3 hp per litre for the restyled 197 hp 3.5 AT.
Hyundai XG performance and MPG
Fuel use is stated in l/100 km because MPG figures are not measured in the supplied data.
| Version | Period | 0–100 km/h | Top speed | City | Highway | Combined |
|---|---|---|---|---|---|---|
| 2.4 MT | Oct 1998–Jul 2003 | not measured | 170 km/h | not measured | not measured | not measured |
| 2.5 AT | Oct 1998–Jul 2003 | 10.1 s | 183 km/h | 13.7 l/100 km | 7.5 l/100 km | 9.8 l/100 km |
| 2.5 MT | Oct 1998–Jul 2003 | 9.1 s | 213 km/h | 14 l/100 km | 9 l/100 km | 10.3 l/100 km |
| 3.0 AT, 188 hp | Oct 1998–Jul 2003 | 9.5 s | 225 km/h | 16.2 l/100 km | 8.6 l/100 km | 11.3 l/100 km |
| 3.0 AT, 192 hp | Oct 1998–Jul 2003 | 8.9 s | 225 km/h | 15.3 l/100 km | 8 l/100 km | 10.7 l/100 km |
| 3.5 AT, 194 hp | Oct 1998–Jul 2003 | not measured | not measured | 13.1 l/100 km | 9 l/100 km | 11.2 l/100 km |
| 2.5 AT | Jul 2003–Apr 2005 | 10.1 s | 183 km/h | 13.7 l/100 km | 7.5 l/100 km | 9.8 l/100 km |
| 2.5 MT | Jul 2003–Apr 2005 | 9.1 s | 213 km/h | 14 l/100 km | 9 l/100 km | 10.3 l/100 km |
| 3.0 AT, 188 hp | Jul 2003–Apr 2005 | not measured | not measured | not measured | not measured | not measured |
| 3.5 AT, 197 hp | Jul 2003–Apr 2005 | 8.6 s | 230 km/h | 17.7 l/100 km | 8.7 l/100 km | 12 l/100 km |
The transmission choice matters as much as the engine in the two 2.5 versions. The 2.5 MT is 1 second quicker to 100 km/h and has a top speed 30 km/h higher than the 2.5 AT. The trade-off is consumption: the 2.5 AT uses 0.5 l/100 km less on the combined cycle, 0.3 l/100 km less in the city and 1.5 l/100 km less on the highway.
Between the two earlier 3.0 AT entries, the 192 hp version adds 4 hp and 5 Nm. It accelerates 0.6 seconds faster while using 0.6 l/100 km less combined, 0.9 l/100 km less in the city and 0.6 l/100 km less on the highway. Both have the same measured top speed of 225 km/h. On the supplied figures, the 192 hp 3.0 AT is therefore the stronger pre-restyling 3.0 choice.
The restyled 3.5 AT is 0.3 seconds quicker to 100 km/h than the earlier 192 hp 3.0 AT and raises top speed by 5 km/h. Its combined consumption is 1.3 l/100 km higher and its city consumption is 2.4 l/100 km higher, so the extra performance carries a measurable fuel penalty.
Hyundai XG dimensions, weight and capacity
Every Hyundai XG version has 160 mm of ground clearance and a 70-litre fuel tank. Wheel sizes are not measured for any listed version.
| Version | Period | Kerb weight | Gross weight | Ground clearance | Tank | Wheel sizes |
|---|---|---|---|---|---|---|
| 2.4 MT | Oct 1998–Jul 2003 | 1865 kg | 2455 kg | 160 mm | 70 l | not measured |
| 2.5 AT | Oct 1998–Jul 2003 | 1506 kg | 2090 kg | 160 mm | 70 l | not measured |
| 2.5 MT | Oct 1998–Jul 2003 | 1640 kg | 2130 kg | 160 mm | 70 l | not measured |
| 3.0 AT, 188 hp | Oct 1998–Jul 2003 | 1679 kg | 2170 kg | 160 mm | 70 l | not measured |
| 3.0 AT, 192 hp | Oct 1998–Jul 2003 | 1579 kg | 2170 kg | 160 mm | 70 l | not measured |
| 3.5 AT, 194 hp | Oct 1998–Jul 2003 | 1656 kg | not measured | 160 mm | 70 l | not measured |
| 2.5 AT | Jul 2003–Apr 2005 | 1506 kg | 2090 kg | 160 mm | 70 l | not measured |
| 2.5 MT | Jul 2003–Apr 2005 | 1640 kg | 2130 kg | 160 mm | 70 l | not measured |
| 3.0 AT, 188 hp | Jul 2003–Apr 2005 | 1650 kg | not measured | 160 mm | 70 l | not measured |
| 3.5 AT, 197 hp | Jul 2003–Apr 2005 | 1795 kg | 2230 kg | 160 mm | 70 l | not measured |
The 2.5 AT has the lightest stated kerb weight at 1506 kg and the best weight-to-power figure at about 9.2 kg per hp. The earlier 192 hp 3.0 AT follows closely at about 8.2 kg per hp and is actually better by this measure. The restyled 3.5 AT weighs 1795 kg, giving about 9.1 kg per hp. The 2.4 MT is the least favourable at about 13.4 kg per hp.
The 2.5 MT weighs 134 kg more than the 2.5 AT despite sharing its 163 hp and 230 Nm output. Its quicker measured acceleration therefore accompanies the Manual gearbox rather than a power advantage.
Hyundai XG problems and reliability
Problems, common faults, check-engine-light causes, firing order and reliability records are not measured in the supplied data. These points cannot be used to rank the versions. Any purchase inspection must therefore treat condition and maintenance evidence separately from this specifications comparison.
Which Hyundai XG version should you buy?
Choose the 2.5 AT if measured fuel consumption and low kerb weight matter most. Its 9.8 l/100 km combined figure is the lowest listed, and its 1506 kg kerb weight is also the lowest. The compromise is performance: its 10.1-second acceleration time and 183 km/h top speed trail the 2.5 MT.
Choose the 2.5 MT if you want the best balance of measured acceleration and consumption among the smaller engines. It reaches 100 km/h in 9.1 seconds, only 0.2 seconds behind the earlier 192 hp 3.0 AT, while using 0.4 l/100 km less combined. It also delivers the catalogue’s highest power per litre at about 65.4 hp.
Choose the pre-restyling 3.0 AT with 192 hp if you want the most compelling Automatic compromise. Compared with the 188 hp 3.0 AT from the same period, it is more powerful, quicker, lighter by 100 kg and more economical in every measured consumption cycle. Its approximately 8.2 kg-per-hp ratio is the best in the catalogue.
Choose the restyled 3.5 AT with 197 hp when outright measured performance takes priority. It has the highest output, the quickest 0–100 km/h time and the highest top speed, but it also records the highest combined consumption at 12 l/100 km and the highest city figure at 17.7 l/100 km.
The 2.4 MT is the least convincing choice on specifications alone: it has the lowest output, the lowest measured top speed and the highest kerb weight. Its acceleration and consumption are not measured, so the data do not establish a compensating performance or economy advantage.
