Following the success of its TDI and FSI engines, Volkswagen is launching the latest in a line of pioneering inventions with the introduction of TSI petrol technology.

FSI uses the direct injection of petrol into the combustion chamber to improve efficiency and hence reduce fuel consumption and emissions. Taking this further, TSI uses — for the first time ever — an FSI engine which is then dual-charged through a combination of an engine driven supercharger and an exhaust gas turbocharger arranged in series.

The driving characteristics of the new TSI engine are improved over those of the current FSI unit. The belt-driven supercharger operates at the lower engine speeds, with the turbocharger coming in as engine speed increases. The result of this is excellent driveability and performance throughout the range with no turbo lag and high maximum torque.

Key to the TSI’s success is that direct injection allows an abnormally high compression ratio of 10:1 to be used in conjunction with high maximum boost pressure of up to 2.5 bar absolute. This enables the relatively small engine to use very high gearing to provide exceptional fuel efficiency for a petrol engine, particularly at motorway cruising speeds. As an additional bonus, the TSI engine provides driver enjoyment, producing high power and torque across a rev range from 1,000 to 6,500 rpm.

The new TSI engine has a capacity of 1.4-litres (1,390 cc) and produces either 140 or 170 PS. The 170 PS version has the same peak power as a conventional 2.3-litre petrol unit but with 20 per cent lower fuel onsumption, returning 38.2 mpg on the combined cycle. It also produces impressive torque of 177 lbs ft (240 Nm) from 1,750 through to 4,500 rpm. All TSI engines drive through a manual six-speed gearbox. A DSG automatic option is also available with the 170 PS engine. This will be offered later in the year with the 140 PS unit.

TSI technology has already received international acclaim, having been named Best New Engine of 2006 in the International Engine of the Year Awards. It also won the 1-litre to 1.4-litre category.

Thank you for reading this post.





  1. I use 95 unleaded, and have the same power…
    The difference between this and an aftermarket engine, is this power has to come from normal fuel.

  2. I have the SEAT Leon with a 90kw engine.
    Why that? it has the same mechanical parts as the golf, yet 10,000$ cheaper.
    The interior quality suffers, I know, but I bought this car for the sole purpose of sporty driving, and, trust me, it delivers spectacularly.
    currently producing 125bhp and 200nm of torque
    when I chip-tune it, it will be 158bhp and 270nm.
    can't wait.

  3. Those newer generation engines are less reliable and more costly in maintenance.

    Maybe FSI is more reliable than TSI…

    The engine provide the lowest fuel consumption per horsepower per hour – 140-150 grams. The highest mechanical efficiency over – 90%.
    The smallest metal consumption per horsepower and thus the lowest weight of the structure. The lowest atmospheric emissions.

  5. I'm really happy with the 1.4 TSI in my Skoda Octavia. It's a dream to drive, coupled to the 7 speed DSG. Gives good mpg too on a motorway journey.

  6. @Robert Urban! Are you being genuinely serious!!? The old 1.9 tdi has arguably been one of the most bomb proof engines! my dad had a mkiii which did 220k miles no problems! ive got a mkv on 140k and engine is still solid as a rock! plus which tsi and which tdi are you commenting on?? the 1.6 tdi or the 3l v6? or perhaps the 1.2 R4 tsi or the 3.0 v6 tfsi!!? 

  7. All 1-4 turbocharger intercooler with petrol engines in Brands : unstable acceleration,no economy,expensive repair,easy damage from all drivers,easy error ecu 

  8. Problems: The engine exhaust 1000 times more particles than a modern diesel engine with particulate filters [TV germany: "VOX auto mobil", 26.01.2014]. Over the EGR comes the particles to the intake side and pollute the inlet valves. The exhausts get more and more toxic and the engine can fail. This is an gradual process and a expensive problem for the car owner.

  9. TSI turbochager : easy damage,no economy,overload,unstable poweroutput,unstable acceleration by their knowledge because they use cg antimation and don't test level Formula 1.

  13. I have owned a 1.8 tsi Jetta for five months, purchased new.

    – exceptional performance, in particular the torque delivery, behaves like a midsize V-8
    – exceptional fuel economy, I drive 120 kms/day, round trip. Average fuel economy typically mid-5-liter/100 kilometres
    – extremely happy with the all-around package of performance/handling/build quality

    On the down side, car is in getting a clutch problem diagnosed under warranty. Intermittent chattering, not related to driver error. Also, having previous experience with turbos, purchased extended warranty (to 200,000) in case turbo technology isn't sustainable over the long term. 

  14. These TSI engines are now suffering from a lot of major engine failures at low mileage too. Timing chain problems and piston/ring problems.VW has pushed the envelope too far and unfortunately the consumer is paying the price.Avoid at all cost.This engine is a liability. Stick with diesel or higher cc normally aspirated for lower maintenance.

  15. Купил тси, наелся я с этим конструктором. Самый ненадежный и нересурсный мотор. ВАГ в топку с их моторами и роботами. Больше никогда не куплю.

  16. Great engines- had mine for over 180,000kms.. no problems apart from standard servicing requirements. Prefect combination of power and low fuel consumption.

  17. I own a VW Golf 1.4 tsi.
    After only 5000km this engine starts shaking when running idle.
    I don't find this normal, do you, but VW finds that an engine that runs irregular is normal !!!
    And won't do anything about it, even in warranty period !!!
    You pay a lot of money for a shaky engine, and what about the long term damage.
    The joke (bill) is on you.

  18. TSI engines turbo intercooler all : 20-100 l/100km, over 100 l/100km, easy damage

    End report from VW database engines.

    Because VW agents hide these data from CEO.

  19. I own vw gold mk 6 1.4 TSI 118 KW 2010 with less than 100k on the clock and I have low compression in the cylinder 4 and misfiring. I just rang VW Australia and they said the car is out of the warranty, so you are on your own. Great service and reliability VW!

  20. These engines have proved to the unreliable in the Golfs with alot of failures reported at enormous cost eg. new engine. In particular the timing chains can slip causing damage to the engine. Apart from the reliability issues, it was a great idea though.
