Full jac js4 specs guide: a 5-door SUV built since 2021 with 118–147 hp, FWD, and manual or CVT gearboxes — plus advice on which version to choose.
The JAC jS4 is a 5-door SUV produced from 2021 to the present, offering between 118 and 147 hp from front-wheel-drive powertrains with either a manual gearbox or a CVT. If you are checking jac js4 specs while shopping for a compact family SUV with straightforward mechanicals and a single, current generation to choose from, this model fits that brief.
JAC jS4 generations
1 generation (2021–present)
The first and only generation of the JAC jS4 has been in production since 2021 and comes exclusively as a 5-door SUV with front-wheel drive. Its power range spans 118 to 147 hp across 3 modifications, with buyers choosing between a manual transmission and a CVT. The core of the lineup is the 1.5-litre turbocharged engine: the JAC jS4 1.5 T i MT (1st generation) pairs a 1499 cc unit producing 147 hp with a manual gearbox, while the JAC jS4 1.5 T i CVT (1st generation) delivers the same 147 hp through a CVT. Both of these versions sit at the top of the model's output range, a full 29 hp above the 118 hp entry point.
Which JAC jS4 to buy
- 1.5 T i MT (1 generation): the widespread choice of the range, with the full 147 hp output from its 1499 cc turbocharged engine and a manual gearbox for direct control.
- 1.5 T i CVT (1 generation): the most powerful configuration paired with two-pedal convenience — the same 147 hp and 1499 cc displacement, but with a CVT that suits city driving.
On the used market the picture is simple: every JAC jS4 belongs to the same generation, built from 2021 onward, so there are no cross-generation compatibility questions and even the earliest cars are relatively recent. The main decision is transmission type, since the engine hardware at the 147 hp level is shared between the manual and CVT versions.
Summary
The JAC jS4 lineup is compact and easy to navigate: one generation from 2021 to the present, one body style (5-door SUV), one drive layout (FWD), and 3 modifications spanning 118 to 147 hp. The 147 hp 1.5-litre turbo versions — the JAC jS4 1.5 T i MT and the JAC jS4 1.5 T i CVT — represent the top of the range, and the choice between them comes down entirely to gearbox preference. Buyers wanting the strongest jS4 lose nothing by picking either one, as both share the same 1499 cc engine and identical peak output.
