Skoda Octavia 1.8 TSI Elegance Review | New Skoda Octavia | Octavia 1.8 | New Octavia Cars

Skoda's new turbocharged Octavia 1.8 TSI is both frugal and powerful

Thats a good reivew , Im actually quite surprised that its so close to the vRS performance wise , 140mph is a decent maximum for a car thats not overtly 'sporty'. 38MPG too...not too shabby.

What's a TSi? How does it differ from an FSi or a TFSi ? Please...?

So, is this just a new generation 20vt engine? It says it's a 1.8 turbo, but not how many valves the engine has. Looks like an interesting engine though.

That's the TSI that's in the Golf GT - A 1.4 with a turbo and a supercharger. This 1.8 TSI is just a turbo only, but has 0.4 more litres.

Noticed that the Skoda website calls it the 1.8T FSI engine. Looks like auto express got it wrong.

OK, for smaller engine - nonetheless......

Operating principle

The new 90-kW TSI

Effective actions taken to reduce fuel consumption and improve driving dynamics are direct gasoline injection, engine charging and reduction of engine displacement. Volkswagen is taking precisely this approach in its TSI engines: Reducing engine displacement, and thereby lowering friction and throttle adjustment losses, results in lower specific fuel consumption and a higher level of efficiency. Depending on the performance class, this is done either by a combination of turbocharger and supercharger, or simply with a specially developed turbocharger as on the new TSI.

The TSI, which is 90 kW strong over a wide range from 5,000 to 6,400 rpm and offers a very high specific torque of 144 Newton-meter per liter, delivers exceptionally agile response even from very low engine speeds without the addition of a supercharger. There is no turbo hole here. When it comes to forming the charge mixture, Volkswagen implements, and this is the case in its TDI engines as well as the TSI, a combination of engine charging and direct injection. Here too it is clearly evident that gasoline direct injection and engine charging complement one another ideally and together enable an unprecedented increase in efficiency.

From what I've been able to gather on google in the meantime it seems FSI is an injection method, and TSI means the dual boosted engine or "twincharger". So one must assume TFSI means FSI with a turbo bolted on, although I can't find anything that confirms that for definite.

Correct.

This is basically the same design as the 2.0 TFSI used in the VRS , but with 10% less capacity

So many letters, almost infinite combinations :P

TBH I was thinking more on the lines

That fookin shifting innit

But less power than the TFSI....
