The Jetta TSI is identical to the TDI on the outside, except for the badging. The interior too is virtually identical, barring a different gear-knob design and a redline marked at 6,000 RPM on the instrument cluster. Steering and brake feel are exactly the same as in the diesel. Here’s another difference – the TSI’s clutch is fairly light and easy to use, unlike the diesel Jetta that has a noticeably heavier clutch, with a slightly shorter throw.
You do have to press the clutch to crank the engine. At idle, the engine has a certain audible thrum to it. I was quite surprised at being able to hear the petrol engine so distinctly at idle. What’s more, slight vibrations can be felt on the clutch pedal too. On the inside, it sounds more like a very well-refined diesel rather than a D-segment petrol car. I even had a friend casually ask if it was a diesel, while a Jetta TDI owner commented that it sounds similar to his car on the inside (his driving impression is in a post below).
The
instant-ness of the throttle response on the petrol is an advantage over the diesel (especially below 2,000 RPM). Driveability in traffic is good, it beats the Civic here by a good margin. On a hill though, you can't start pulling away from low in the RPM range, the car will only really start to move post 1,400 RPM - expected of a turbocharged car. Its a very malleable engine. You can hang around in a chosen gear and you won’t have to worry about shifting up or down too often. The Jetta TSI has enough power through the range to move you around, even from as low as 1,000 RPM in typical city conditions. At 3,600 RPM, there is a small spike in power as the turbo gets into the zone, but its hardly a rush. At 5,500 RPM, it starts to run out of breath (peak power is at 5,000 RPM). 0-100 km/h is decently placed in the 10 second range.
The difference between the Jetta’s 1.4 TSI and the Laura's 1.8 TSI is, though they have the same linear style of power delivery (obviously in differing magnitudes), the 1.4 TSI doesn’t have the same silky smooth refinement throughout the RPM range. The 1.8 TSI engine feels just as refined and capable at 3,000 as it does at 5,000 RPM. The 1.4 TSI starts to show signs of it being taxed heavily as you approach 5,000 RPM. Refinement aside, the Laura 1.8 TSI blows the Jetta 1.4 TSI away when it comes to performance.
The 6-speed gearbox is smooth and fairly light, very similar to other cars from the VW family, though there is a slightly different feel between the petrol and diesel Jetta boxes. The diesel feels a little more notchy, with the gates being better defined. The petrol’s gearbox is vaguer in comparison. The gates are very close too...sometimes getting into 6th gear requires a conscious effort to pull the gear lever towards you as you move it down, else you end up slotting into 4th. It's the same when trying to downshift to 5th – you sometimes end up in 3rd. This could take a little getting used to. Gearing has 1st topping out at an indicated 53 km/h, and 2nd at 103 km/h. The 6th gear is a huge boon, making high-speed cruising a pleasure, especially since the dynamics of the Jetta mask higher speeds beautifully.
Turn the music and the AC off, and you’ll notice a definite
boomyness coming from the engine bay, even when you lift off the accelerator! At low RPMs (2,000), because of the engine's gruff note, it seems like its revving a lot higher and harder than it actually is. To nitpick, you can feel a faint vibration on the gearshift as well at 3,000 RPM. The unmistakable BOV noise is quite noticeable every time you come off the accelerator, but only when the windows are down; petrol-heads will enjoy this. On the flip-side, its good to have some audible feedback when you are having fun with the car. Maybe it even makes the Jetta TSI feel faster than it is.
The 1.4 engine might not be extremely sprightly, yet it’s a pretty good engine on its own. Mated with this platform of good neutral handling, solid build, sharp brakes and smooth gearbox, the Jetta TSI is still a car you can have fun with on a twisty road. On spirited
ghat sections, 2nd gear is phenomenal. Everything from 25 km/h to 103 km/h is covered. You don’t need to worry about shifting gears except for super-tight hairpins. There isn’t a huge amount of power for a car this size – but for a 1.4, its pretty entertaining.
We noticed a lot of wind noise. Even at speeds like 80 km/h, a swishing sound was evident from the A-pillar area. However, this could be due to it being a very windy pre-monsoon day, since no other Jetta owners we checked with mentioned the issue.
A bit of free space in there?
TDI badging says “2.0 TDI”, this just says "TSI"
Tailpipes are identical between the petrol and the diesel:
Loved this. Rather than all the confusing pull or slide-type latches for opening the bonnet, here you just lift. One motion, very intuitive:
