Chevrolet Sonic

Which Chevrolet Sonic Version Should You Buy?

The Chevrolet Sonic is a FWD Sedan with one generation represented in two stages: the original model from January 2011 through April 2016 and its first restyling from May 2016 onward. The original catalogue contains 13 modifications, with 12 shown in the supplied data, while the restyling contains 6 entries.

The Chevrolet Sonic is a FWD Sedan with one generation represented in two stages: the original model from January 2011 through April 2016 and its first restyling from May 2016 onward. The original catalogue contains 13 modifications, with 12 shown in the supplied data, while the restyling contains 6 entries. The key buying decision is between the original car’s broader engine selection and the restyled car’s simpler range. For maximum output, the original 1.4 AT and 1.4 MT with 140 hp lead the catalogue; for the strongest torque relative to displacement, the turbocharged 1.4 versions deliver 200 Nm from about 1.36 litres. Buyers prioritizing measurable economy have more evidence for the original generation because consumption and acceleration figures are not measured for the restyled versions.

Chevrolet Sonic generations and versions

The original Chevrolet Sonic generation ran from January 2011 through April 2016 as a Sedan. Its listed choices include 1.4 AT and 1.4 MT turbo versions with 140 hp, several 1.4 AT and 1.4 MT entries rated at 101 or 138 hp, naturally aspirated 1.8 MT and 1.8 AT versions with 135 hp, and 1.6 AT versions with 116 hp. This is the generation to examine when acceleration, fuel use, ground clearance, wheel sizes, or maximum speed must influence the purchase, because at least some versions provide those measurements.

The first restyling began in May 2016 and is also a Sedan. Its 6 catalogue entries comprise 1.4 T AT, 1.4 T MT, 1.8 AT, 1.8 MT, 1.4 AT, and a second 1.4 T AT entry. The turbo 1.4 T AT and 1.4 T MT produce 138 hp and 200 Nm, while the 1.8 AT and 1.8 MT produce the same 138 hp but 170 Nm. A 1.4 AT provides 101 hp, although its torque is not measured. The restyling therefore makes the clearest comparison possible: equal-power turbo and naturally aspirated engines with markedly different torque delivery.

Duplicate version names are identified below by power or by catalogue stage so that similarly named modifications remain distinguishable.

Among the restyled 138 hp cars, the 1.4 T engine produces about 101.2 hp per litre, compared with about 76.8 hp per litre for the 1.8. Both deliver equal peak power, but the 1.4 T supplies 30 Nm more torque and reaches its 200 Nm peak at 1850 rpm; the 1.8 reaches 170 Nm at 3800 rpm. These figures give the 1.4 T AT and 1.4 T MT the stronger numerical case when low-rpm torque matters.

The original 140 hp 1.4 engine achieves about 102.8 hp per litre, the highest specific output in the supplied catalogue. The original 138 hp 1.4 versions produce about 101.2 hp per litre, whereas the 135 hp 1.8 versions produce about 75.2 hp per litre. The 116 hp 1.6 AT versions sit between them at about 72.6 hp per litre.

Chevrolet Sonic performance, mpg and economy

The original 1.4 MT with 140 hp records the quickest measured acceleration, reaching 100 km/h in 8.8 seconds. Its 1.4 AT counterpart requires 9.3 seconds, a difference of 0.5 seconds. Another original 1.4 MT with 138 hp records 8.5 seconds, while the 1.4 AT entries with 101 or 138 hp record 9 seconds. Fuel consumption for the 138 hp 1.4 MT is 8.1 l/100 km in the city, 5.8 l/100 km on the highway, and 7.1 l/100 km combined. The comparable listed 1.4 AT figures are 8.7, 6.3, and 7.6 l/100 km, so the Manual uses 0.6 l/100 km less in the city, 0.5 less on the highway, and 0.5 less combined.

The original 1.8 MT with 135 hp has two recorded sets of economy data. One lists 7.7 l/100 km city, 5.6 highway, and 6.8 combined; another lists 9.4 city, 6.7 highway, and 7.8 combined. Both record 9.9 seconds to 100 km/h. The 1.8 AT data also vary by entry: one records 8.3 city, 5.5 highway, and 7.1 combined with acceleration in 10.3 seconds, while another records 9.4 city, 6.7 highway, and 8.4 combined with acceleration in 9.9 seconds. Buyers should therefore match the exact catalogue modification rather than treating every 1.8 AT or 1.8 MT as interchangeable.

The two original 1.6 AT entries both list 7.1 l/100 km combined. The 1162 kg car records 8.9 city and 5.3 highway, accelerates to 100 km/h in 11.3 seconds, and reaches 189 km/h. The 1168 kg car records 9.9 city and 5.5 highway, accelerates in 9.3 seconds, and reaches 186 km/h. That leaves a trade-off within the supplied figures: the lighter entry has the higher maximum speed and lower city consumption, while the heavier entry is 2 seconds quicker to 100 km/h.

For every restyled version—1.4 T AT, 1.4 T MT, 1.8 AT, 1.8 MT, and 1.4 AT—acceleration to 100 km/h, maximum speed, city consumption, highway consumption, and combined consumption are not measured. A numerical economy or performance verdict cannot be made for those cars from the supplied data.

Chevrolet Sonic dimensions, weight and capacities

Overall length, width, and other external dimensions are not measured for either catalogue stage. Every listed Sonic has a 46-litre fuel tank.

Original-generation ground clearance is listed as either 125 mm or 133 mm, depending on the exact entry. Cars with 125 mm clearance may list 195/65 R15, 205/55 R16, and 205/50 R17 wheel sizes. Wheel sizes for entries with 133 mm clearance are not measured.

Measured original kerb weights range from 1162 kg to 1237 kg. The 1162 kg 1.6 AT has exactly 10.0 kg per horsepower, while the 1168 kg 1.6 AT has about 10.1 kg per horsepower. The 1220 kg 1.4 MT with 138 hp has about 8.8 kg per horsepower; the 1220 kg 1.4 AT with 101 hp has about 12.1 kg per horsepower. At identical measured weight, the 138 hp car therefore carries about 3.3 kg less for each horsepower. The 1220 kg 1.8 versions with 135 hp have about 9.0 kg per horsepower. Gross weight is not measured for most versions, but the two 1.6 AT entries list 1598 kg and 1613 kg respectively.

Restyled kerb weight depends on the powertrain. The 1.4 T MT weighs 1267 kg, giving about 9.2 kg per horsepower. The 1.8 AT and 1.8 MT each weigh 1287 kg, or about 9.3 kg per horsepower. The 1.4 T AT weighs 1320 kg, or about 9.6 kg per horsepower, while the 101 hp 1.4 AT also weighs 1320 kg and has about 13.1 kg per horsepower. Choosing the restyled 1.4 T AT over the 1.4 AT adds 37 hp at the same listed kerb weight. Ground clearance, gross weight, and wheel sizes are not measured for all restyled versions.

Which Chevrolet Sonic version to buy and why

For the strongest restyled specification, choose 1.4 T MT if a Manual is acceptable. It matches the 1.4 T AT at 138 hp and 200 Nm but weighs 53 kg less, improving the calculated power-to-weight figure from about 9.6 to about 9.2 kg per horsepower. Its torque peak also arrives at 1850 rpm. The trade-off is a 5-speed Manual instead of a 6-speed Automatic.

For an Automatic in the restyled range, 1.4 T AT has the best numerical argument. It equals the 1.8 AT at 138 hp, produces 30 Nm more torque, reaches peak torque 1950 rpm earlier, and uses 432 cc less displacement. The 1.8 AT is 33 kg lighter, but its calculated 9.3 kg per horsepower remains slightly better than the 1.4 T AT’s 9.6 only because of weight; it does not offset the turbo car’s torque advantage on the available figures.

The restyled 1.4 AT is the least performance-focused option. It has 101 hp, 37 hp less than the 1.4 T AT, despite both listing a 1320 kg kerb weight. Its torque and boost status are not measured, so a more detailed performance comparison would be speculative.

Choose an original-generation car if measured acceleration and fuel consumption matter more than the later catalogue stage. The 138 hp 1.4 MT combines 8.5-second acceleration with 7.1 l/100 km combined consumption, while the comparable listed 1.4 AT takes 9 seconds and uses 7.6 l/100 km combined. Buyers wanting an Automatic with a measured top speed can consider the 1.6 AT, but they must distinguish its two data entries carefully because their acceleration, maximum speed, consumption, and weight figures differ.

The catalogue contains no prices, sale listings, reliability records, fault rates, maintenance costs, or evidence identifying Chevrolet Sonic years to avoid. It also does not measure engine oil capacity, engine timing condition, engine-mount condition, or engine-light causes. Those questions cannot be used to recommend one version over another here. Based strictly on the recorded specifications, the restyled 1.4 T MT is the power-to-weight choice, the restyled 1.4 T AT is the torque-rich Automatic choice, and the original 138 hp 1.4 MT is the choice supported by the strongest combination of measured acceleration and combined fuel consumption.
