Key Differences
-
The GTI has 94 hp more power
The K4 gives up a lot on total system output: 147 hp, compared with 241 hp on the GTI. Power is only part of the story; weight, gearing and torque delivery shape how quick a car feels.
-
The K4 has better fuel economy
Few buyers will miss this one. The K4 brings 34 mpg to the table; the GTI brings 27 mpg. Better combined fuel economy lowers your running costs every week, and the savings add up over years of ownership.
-
The GTI has 141 lb-ft more torque
When it comes to torque, the GTI wins comfortably with 273 lb-ft against 132 lb-ft. More torque means stronger pulling from low speeds, which you feel when accelerating from a stop or climbing grades.
-
The K4 has better highway fuel economy
It’s a lopsided result (40 mpg for the K4, 32 mpg for the GTI) and one of the main reasons to choose between them. Highway fuel economy matters if you cover long distances at steady speeds.
-
The K4 has better city fuel economy
The spread here is large: 30 mpg on the K4 versus 24 mpg on the GTI. Expect to notice it. City fuel economy matters most if your driving is mostly short trips, traffic and stop-and-go commutes.

Engine & Performance
GTI leads
For engine & performance, the verdict is easy: the GTI leads, and not by a little. The GTI scores with 94 hp more power. More power helps with merging, overtaking and climbing hills, especially with passengers and luggage on board. If this section decides it for you, choose the GTI.
Total system output
K4: 147 hp GTI: 241 hp The GTI’s extra output gives it more in reserve when you need to get up to speed.
Torque
K4: 132 lb-ft GTI: 273 lb-ft Electrified powertrains deliver torque instantly, so compare torque figures alongside the powertrain type.
Fuel Economy & Range
K4 leads
On fuel economy & range, the gap between these two is wide, and it favors the K4. Choose the K4 and you get better fuel economy. The K4 uses less fuel on the standard combined cycle, which matters most if you drive a lot. Bottom line for fuel economy & range: the K4 has the edge.
Fuel economy (combined)
K4: 34 mpg GTI: 27 mpg Official figures rarely match real-world driving exactly, but the ranking between two cars tends to hold.
Fuel economy (highway)
K4: 40 mpg GTI: 32 mpg Speed, wind and load affect highway use a lot, but the official rating is a fair comparison point.
Space & Practicality
Too close to call
This area ends level; whatever separates these two, it isn’t space & practicality. For space & practicality, pick whichever you prefer for other reasons.
Off-road & Towing
Too close to call
You can skip ahead if off-road & towing was your deciding factor: the two are evenly matched here. The takeaway: off-road & towing is not where these two differ.
