The Hyundai Sonata catalogue covers 13 generations, with 11 generation entries shown here, all as Sedan models. The available records run from the first generation of 1985–1987 to the eighth generation of 2019–2023. Choosing between them is chiefly a choice between simpler rear-wheel-drive early cars, later FWD sedans with manual or automatic gearboxes, economical Diesel, LPG, Hybrid and Plug-in versions, and high-output turbocharged Gasoline models. This guide compares only the specifications supplied in the catalogue; prices, equipment, problems and reliability are not measured.
Hyundai Sonata generations compared
The first generation, produced from 1985 to 1987, has 4 versions. Its 1.8 MT and 1.8 AT produce 100 hp and 150 Nm, while the 2.0 MT and 2.0 AT deliver 110 hp and 167 Nm. Every listed version is RWD; the manuals have 5 gears and the automatics have 4.
The second generation, from 1988 to 1993, is a Sedan with 9 versions and moves to FWD. Its Gasoline engines range from the 95 hp 1.8 MT and 1.8 AT to the 146 hp 3.0 AT. The 131 hp 2.0 MT reaches 100 km/h in 10.2 seconds, making it 3.2 seconds quicker than the equivalent 2.0 AT at 13.4 seconds. Both return combined consumption of 8.4 and 8.8 respectively.
The third generation, from 1993 to 1996, has 7 Sedan versions. Choices extend from the 98 hp 1.8 MT and 1.8 AT to the 146 hp 3.0 AT. The 139 hp 2.0 MT reaches 100 km/h in 10.2 seconds and 195 km/h; the corresponding 2.0 AT requires 12.8 seconds and reaches 190 km/h. The 1996–1998 restyling adds 14 versions, including outputs from 95 hp to 146 hp and an LPG 2.0 MT with 106 hp.

Outputs range from 146 hp for the LPG 2.0 AT to 290 hp for the Gasoline 2.5 AT. Search terms such as “Hyundai Sonata 2024,” “Hyundai Sonata 2025” and “Hyundai Sonata 2026” fall outside the supplied production data, as do equipment labels such as Limited and Hybrid Limited.

Hyundai Sonata performance and fuel economy
For maximum acceleration among the measured versions, the sixth-generation turbo 2.0 AT is the standout: 274 hp, 372 Nm and 0–100 km/h in 6.8 seconds. The seventh-generation turbo 2.0 AT needs 7.2 seconds before restyling and 7.5 seconds after restyling, although the latter has the highest measured top speed at 240 km/h. The eighth-generation 290 hp 2.5 AT supplies 422 Nm, but its 0–100 km/h time and top speed are not measured, so the data cannot establish whether it is quicker.
Within the eighth generation, the Plug-in 2.0 AT reaches 100 km/h in 8.5 seconds and 200 km/h. The turbo 1.6 AT is only 0.1 seconds slower at 8.6 seconds and reaches 210 km/h. The 180 hp 2.5 AT takes 9.2 seconds, whereas the 150 hp 2.0 AT needs 10.6 seconds: the extra 30 hp cuts 1.4 seconds from the acceleration time.
The eighth-generation Hybrid 2.0 AT records combined consumption of 5.0 and 118 g/km of CO₂. Its city and highway figures are not measured. The 194 hp Gasoline 2.5 AT returns 8.4 city, 6.2 highway and 7.4 combined, while the turbo 1.6 AT returns 8.7, 6.5 and 7.6. The 180 hp 2.5 AT records 7.7 combined, and the 150 hp 2.0 AT records 7.8. The 290 hp 2.5 AT consumes 8.7 combined, exactly 1.3 more than the 194 hp 2.5 AT, while adding 96 hp and 176 Nm.
The LPG 2.0 AT has the eighth generation’s highest measured combined figure at 10.2, with 11.5 city and 8.7 highway. The Plug-in 2.0 AT has no measured city, highway or combined consumption figure, so its economy cannot be compared numerically here.
Hyundai Sonata dimensions and weight
The eighth-generation kerb-weight range runs from 1388 kg for the Hybrid 2.0 AT to 1611 kg for the 290 hp 2.5 AT. Gross weight ranges from 1977 kg for the 194 hp 2.5 AT and 1.6 AT to 2070 kg for the 290 hp 2.5 AT; gross weight for the LPG 2.0 AT is not measured.
Power-to-weight helps separate versions with similar consumption. The eighth-generation 290 hp 2.5 AT carries about 5.6 kg per hp, compared with about 7.5 kg per hp for the 205 hp Plug-in 2.0 AT, about 7.9 kg per hp for the 180 hp 1.6 AT, and about 10.2 kg per hp for the 150 hp 2.0 AT. The Hybrid 2.0 AT combines 192 hp with 1388 kg, or about 7.2 kg per hp.
Ground clearance is 155 mm where measured for the eighth-generation 150 hp Gasoline 2.0 AT, 180 hp 2.5 AT, LPG 2.0 AT, Plug-in 2.0 AT and Hybrid 2.0 AT. It is not measured for the 194 hp 2.5 AT, 1.6 AT or 290 hp 2.5 AT. Most eighth-generation versions have a 60-litre tank; the LPG 2.0 AT has 64 litres.
Listed eighth-generation wheel sizes are 205/65 R16, 215/55 R17 and 235/45 R18 for most versions. The 180 hp 2.5 AT instead starts with 215/60 R16 before 215/55 R17 and 235/45 R18. Wheel sizes for the Hybrid 2.0 AT and Plug-in 2.0 AT are not measured.
Hyundai Sonata problems and reliability
Mechanical problems, repair frequency, service costs and reliability ratings are not measured in the supplied data. The specifications can identify performance, fuel use, weight and chassis differences, but they cannot support a claim that one Sonata engine, gearbox or generation is more reliable than another.
Which Hyundai Sonata version to buy and why
Choose the eighth-generation Hybrid 2.0 AT if the priority is the lowest measured combined consumption. Its figure is 5.0, which is 2.4 lower than the 194 hp 2.5 AT and 3.7 lower than the 290 hp 2.5 AT. It also produces 192 hp and 375 Nm, reaches 100 km/h in 9.2 seconds and has the lightest measured eighth-generation kerb weight at 1388 kg.
Choose the eighth-generation 290 hp 2.5 AT if power, torque and power-to-weight matter most. It adds 96 hp and 176 Nm over the 194 hp 2.5 AT, while weighing 195 kg more and consuming 1.3 more on the combined cycle. Its acceleration and top-speed figures are not measured, so buy it for its documented output rather than an assumed performance time. The data names this version 2.5 AT; “N Line” is not a supplied version name.
Choose the eighth-generation turbo 1.6 AT as the balanced measured-performance option. Its 180 hp matches the naturally aspirated 2.5 AT, but it produces 270 Nm rather than 232 Nm and reaches 100 km/h in 8.6 rather than 9.2 seconds. Combined consumption is also 0.1 lower at 7.6. Its 112.6 hp per litre exceeds the 72.1 hp per litre of the 180 hp 2.5 AT.
Choose the eighth-generation 194 hp 2.5 AT if you want the lowest measured combined consumption among its conventional Gasoline versions. At 7.4, it uses 0.2 less than the 1.6 AT, 0.3 less than the 180 hp 2.5 AT and 0.4 less than the 150 hp 2.0 AT. It also has an 8-speed Automatic, but its acceleration, top speed and ground clearance are not measured.
For an older performance-focused Sonata, choose between the sixth-generation 274 hp 2.0 AT and the seventh-generation 245 hp 2.0 AT. The sixth-generation car is 0.4 seconds quicker to 100 km/h than the pre-restyling seventh-generation version, while the restyled seventh-generation version provides the measured 240 km/h top speed. Fuel consumption for these specific seventh-generation turbo versions is not measured, preventing a complete economy comparison.
For an older economy-focused choice, the fifth-generation 140 hp Diesel 2.0 MT records 6.1 combined consumption and 305 Nm. It uses 1.6 less than the 152 hp Gasoline 2.0 MT from the same generation, but gives away 12 hp. That trade—more torque and lower measured consumption versus greater Gasoline output—is one of the clearest numerical reasons to choose between those versions.
