K4 vs Jetta
The K4 and the Jetta are two different answers to the same compact car brief, each with its own set of priorities. This is less a contest than a fine-tuning exercise: both cover the same ground, with only a few meaningful gaps.

Key Differences
-
The Jetta has 52 lb-ft more torque
It’s a lopsided result (184 lb-ft for the Jetta, 132 lb-ft for the K4) and one of the main reasons to choose between them. Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type.
-
The Jetta has 11 hp more power
Don’t expect a night-and-day difference here. 158 hp against 147 hp is a small but genuine lead for the Jetta. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board.

Engine & Performance
Jetta leads
The Jetta wins the engine & performance section decisively. The Jetta has the edge with 52 lb-ft more torque. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades. Weighing only engine & performance, the Jetta comes out ahead.
Torque
K4: 132 lb-ft Jetta: 184 lb-ft The Jetta’s extra torque makes it more relaxed when fully loaded or towing.
Total system output
K4: 147 hp Jetta: 158 hp The Jetta’s extra output gives it more in reserve when you need to get up to speed.
Fuel Economy & Range
Too close to call
You can skip ahead if fuel economy & range was your deciding factor: the two are evenly matched here. This section won’t settle the choice, so weigh the other areas more heavily.
Space & Practicality
Too close to call
This area ends level; whatever separates these two, it isn’t space & practicality. Neither car gives you a reason to choose it on space & practicality.
Off-road & Towing
Too close to call
The differences on off-road & towing are small enough to ignore in daily use. For off-road & towing, pick whichever you prefer for other reasons.
