Default VWs next-gen 1.5L TSI engine

Volkswagen has revealed details about its new generation of 1,5-litre TSI petrol engines.

The new 1.5TSI unit offers up to 10 per cent better fuel economy when compared to the old 125PS 1.4TSI unit.

The new EA211 evo engine is expected to debut under the bonnets of the VW Golf, Skoda Octavia, Seat Leon and Audi A3 replacing the existing lineup of 1.4-litre TSI engines in the near future.

The so-called EA211 TSI evo engine will be initially available in two power outputs, 130PS (128hp) and 150PS (148hp). Among its many highlights is the introduction of a turbocharger with variable turbine geometry, a feature only seen in petrol engines of much more expensive machinery, like Porsche’s latest 718 series and the 911 Turbo.

Another highlight of the new turbocharged four-cylinder unit is that it makes its maximum torque available really early, offering 200Nm from just 1.300rpm in the 128hp version. Torque details on the 148hp version have not yet been announced.

The compression ratio is now a rather impressively high 12.5:1, with the engine working under the Miller combustion cycle. The cylinder liners in the aluminium crankcase for the 148hp version are coated using a procedure called the atmospheric plasma spray (APS) which reduces friction on the piston rings and increases the heat dissipation when compared to cast-iron crankcases

Sad amount of power output. Honda has 174bhp from a 1.5, Ford has 180 bhp from a 1.5 and also a 200 bhp from a 1.6. Why is this engine so anemic in comparison?

Relatively low output engine - the norm nowadays is to have engines generate close to 100hp/litre.
BUT, there are upsides to this. Lower power output and a flat torque curve across the working rev range will ensure a very "responsive" engine in car application. Which means the engine (and the driver!) will not be stressed. Which will aid in long engine life.

I would say the engine characteristics are very well judged for everyday applications.

I find the 1.2 TSI more than enough power for zipping thru city traffic. Torque comes in real early and the DSG does a superb job of complementing the engine.

Torque will put smile on your face every single day and every single traffic light. Power will make you feel like a king on long straight flat highway runs.

A fuel efficient 1.5 TSI with torque at 1300 will be a delight to drive, especially if they put this into a small car like Polo. "Polo Abarth" anyone

This should ideally be used to power their Vento / Rapid segment in India. Lower end Octy / Jetta if they wish but really focus on Vento / Rapid segment.

Brilliant torque curve. Love it.

Must be to keep it at bay from the slightly bigger brother, the 1.8 TSI.

I guess this is more of a performance + economy engine rather than an outright powerhouse of a motor. With that mind and healthy torque output, it is not too bad.

AFAIK This engine is a replacement for 1.4 TSI, for a 1.5 liter displacement 148hp is no ways anemic, VW group has the 1.8 TSI to make 180hp. Take the car to a tuner for a remap, he will get you another 100 horses in an instant with a remap.

The real highlight here is introduction of Variable Turbine Geometry in a Petrol engine, which earlier was only available in much more expensive cars, which has resulted in a even more flatter torque curve, which on the graph looks like someone has drawn a line using a ruler. VW claims this engine is 10% more efficient than the already very efficient 1.4 TSI.

Well a 1.6 ecoboost produces way more torque -285Nm and is also ruler flat between 1800 and 5000 rpm. It also produces 200 bhp in the fiesta st. Also that remaps to 270 bhp with minimal changes. If you remap an octy 1.8, the gearbox will get shredded, let alone remap to 270 bhp. So let's not call out tuning options.

Even though the trickle down tech from Porsche is nice, they could have been way more aggressive with the tuning of the engine. This power is hardly more than the previous engine. When the specific output of a modern high performance petrol is 150 HP or more, 100 HP or less for a brand new engine is rather sad.

Compression ratio of 12.something is very odd and quite high for a road car! I don't think such a high compression ratio engine would be able to run on indian fuel.

Tuning the 1.6 Ecoboost from 200 Bhp in the Fiesta st to 270 Bhp isn't done through "minimal changes" by any stretch of imagination. It has all the components of a stage 3 tune. Also that state of tune is at the limits of the engine even though the tuners would have one believe otherwise.

The 1.6 Ecoboost starts at 150 Bhp something that even the unmodded 1.4 TSI now gives out in the new Superb with a torque of 250 Nm from 1500 to 3500 rpm.

Figures of new engines released are at the base level of tune. The 1.5 TSI engine will obviously be tuned according to model hierarchy and market needs just like all the other VW group engines. The 2.0 TDI, for instance, has been tuned to give out 104 Bhp to 190 Bhp in various applications.

Ford has only a 1.0, 1.6 and 2.0. and has to wring the neck of its 1.6 just to keep up with the competition.

That's just 3 of them.

I knew the EcoBoost was used the new RS, GT, F-150 etc. So, did a little research and the following is the full line up. Please note they are used in different states of tune in each configuration across models.

1.0 L - 3 cylinders used in Fiesta

1.5 L - 4 cylinders used in Fusion. (downsized version of the 1.6 below)
1.6 L - 4 cylinders used in Mondeo, Fiesta ST. Rated 180 PS, 244 Nm. So, this one is similar to the 1.8 TSI.

2.0 L - 4 cylinders used in Jags and Land Rovers apart from Fords like S-MAX, Escape
2.0 L - 4 cylinders 'Twin-scroll' used in Everest. Rated 248 PS, 373 Nm.


And now, the not so modest ones.

2.3 L - 4 cylinders used in Focus RS. Rated 355 PS, 475 Nm
2.7 L - V6 used in F-150. Rated 330 PS, 508 Nm
3.5 L - V6 used in Transit, F-150 Raptor, Ford GT. Rated 765 PS, 935 Nm

3.5 L - V6..
What about the V8 and V12's? Ford builds V8 and V12 engines for Aston Martin too at a plant dedicated to Aston Martin inside Ford's engine facility at Niehl that is managed by Aston Martin.

Of course, Ford has a lot more engines - the point was in relation to turbo petrols between 1.0 litre and 2.0 litre.
