Have the 1.2tsi 105 6 speed in my Rapid, punches well above its weight.

Although the Rapid weighs less than the Fabia vRS I just came from...

Does the Rapid retain the old EA111 unit or share the new EA211 unit with the Octavia 3?

New one has Cylinder de-activation?

If yes to the above, then no its the older one

Pretty sure its the older one, but revised from the early ones in 2009 as used in Yeti and Fabia.

Where would I find a code?

None of the 1.2tsi units within the group have cylinder deact as far as I know.

Technology Highlights of the new Generation of Engines

The petrol engines of the new Octavia belong to Volkswagen Group’s EA211 model series. These TSI four-valve four-cylinders set new standards regarding energy efficiency, lightweight design and pulling power. Reduced internal friction and weight as well as optimised thermal management provide for up to 19% lower fuel consumption and emissions.

The EA211 engines are a completely new development. Compared to its predecessor the EA111, the EA211 series is significantly more compact, with installation length 50 mm shorter, thus offering more interior space. The installation position of the engines has also been optimised. Just as in the diesels, the petrol engines are now mounted with the exhaust side facing backwards and tilted at an angle of 12 degrees.

The weight of these petrol engines made of die-cast aluminium is only 97 kg for the 1.2 TSI and 106 kg for the 1.4 TSI. Compared to the EA111 predecessor engines used in the Octavia, this is a reduction of up to 22 kg. The crankshaft alone became lighter by 20 per cent; the connecting rods lost 30 per cent of their weight. In addition the connecting rod bearing journals are now hollow-drilled and pistons now come with flat bottoms, all of them optimised for lower weight.

Regarding thermal management, the EA211 petrol engine is equipped with a modern dual-circuit cooling system. That means that a high temperature circuit with a mechanically driven cooling pump cools the basic engine, while a low temperature circuit flows through the intercooler and the turbo-charger casing. The cylinder-head circuit heats the cabin's interior. The exhaust manifold is integrated into the cylinder head, enabling the engine to warm up more quickly, in turn making heat available quickly for the passenger cabin. At high loads, the exhaust is cooled by the coolant, lowering fuel consumption.

woah, quite a bit then!

Will go do some hunting...

Quick google search and yes it comes with the new EA211

that's a nice touch then as its supposed to be a nice step forward in several key areas according to my local dealer (and the tech waffle posted above!)

Having not driven the older one, I can't comment on if its 'better' but the above tech waffle seems to say it is

Glad it came with a 6 speed box too as I hate 5 speeds now, so old fashioned

Parents have the same Yeti as you btw - lovely to drive. Half your power though...

Agreed, six speed box over a five - did you ever look to see what revs it sat at 70mph? Yeti is a winner for my family, total jack of all trades.

same here, I switched from a 2.0 Octavia Estate to a 1.2 Yeti. I no longer do regular long distances and my son is now older and we don't need to lug a pram / buggy etc around so the yeti is the perfect size for us. He really prefers the increased visibility he gets from the higher seating position too. Great family car.

Buggar I forgot!

Will do it tomorrow, run up the bypass is always welcome.

Skoda al Coda,

Bingo!

Vis-a-vis the super quick 7 speed being able to utilize peak HP over a narrow rev range/power band.

Also Bingo! to whoever mentioned planes and trains utilizing turbos.

Ps

I actually rather prefer a good 5 speed gear box with sensibly spaced ratios, combined with the usueable torque of a diesel.

Compared to the 6 speed where I tend to get mixed up or forget which gear is "right" for particular driving conditions.

Anyway why does the Greenline suffice with a 5 speed not a 6 speed gearbox (weight? perhaps)

Cheers

Marcus

EDITED

I say again, the wee 1.2TSI is a cracker, performance wise.

Though interested to note the real world fuel consumption figs are a trifle oot o kilter wit der published figs..... for the 1.2 TSI

Unlike any reasonable Diesel

Marketing.

Skoda is the "cheap" more basic alternative.

I read in some VW material that the standardised fuel economy test is set up towards a 5 speed box and that although in the real world a 6 speed is better, the 5 speed allows then to claim lower emissions and better economy...a complete con really.

Neither answer as above sounds valid to me

(i) I "know some Skoda varients get a 6 speed box ( & better check the Skoda UK website perhaps )

(ii) phsroberts, further explantion is required as that sounds questionable/logically unsound, cos what about the DSG boxs then?

"The prescribed NEDC test cycle doesn't really do justice to a 6-speed gearbox. A 6-speed gearbox is generally lower-geared from 1st through 5th gear than a 5-speed gearbox. Since the gearshift points in the NEDC test are fixed, however, a vehicle with 6-speed gearbox will tend to run at higher rpm during the test. This generally results in a higher standard fuel consumption than when the identical engine is tested with a five-speed gearbox, despite the fact that, in real-world driving, a 6-speed gearbox can often be more economical."

I couldn't find the exact PDF I read, but the above is an exact quote from a VW PDF explaining the way the engines are tested. I believe that is why you find 5 gears in many of their Eco cars.

That seems a huge flaw in the testing system.

The test should require the vehicle to follow a set pattern of speeds and acceleration, making best use of it's engine and gears as appropriate, just as a driver could in the real world.

That's much harder to standardise though, as each test driver has their own driving style. "Change up at 20mph" ensures consistency.

(Just being Devil's advocate - I agree with you!)

2350rpm at 70mph

2350rpm at 70mph

Same for me, unsurprisingly

Did you ever confirm the engine code? I'm not sure where to look to find out whether ours really 'is' the newer unit. I took mine out for a spin this morning through Warrington to parents' (via a friends house) and then came back on the motorway, 49.1 MPG and I'm pretty confident that I can probably beat that with a bit more luck with traffic lights (and avoiding so much through-town driving which was a bit unnecessary)

If it is the new 1.2, it will have a cam belt, the old unit has a chain...so a pretty easy check.

I very much doubt any existing vag model has the new unit, as it is mounted the opposite way around to the old 1.2, (to weight on the exhaust system) so it would have involved a redesign of the engine bay of an existing model.

2350rpm at 70mph

Thanks, that's lower than I'd have expected so good news! Only thing is, the few bits I can find on the net point to the Rapid using the older original chain based 1.2tsi. Can you point me to th links that say its the new unit? Thanks

It was on skoda's app - news about engines and such like. Will try find it again.

i think i be having the 1.2tsi engine se model ive got the 86b in the roomster good engine so the 105 will be a bit more power

It was on skoda's app - news about engines and such like. Will try find it again.

Still slightly non-plussed about this. It would be 'logical' if our 105PS is the older cam chain based one (the belt/chain would be behind a casing rather than visible as far as I can tell and I have absolutely no intention of dismantling my engine after only 350 miles!) ..... Anyway... I looked in the service book (same info on a sticker under the boot floor) and the engine code given is CBZB.

According to this list the engine is old tech (the CBZA 63kW variant being fitted to Golfs from 2010 for example), 8v rather than 16.

It doesn't bother me though, it's a cracking little engine and I'm really enjoying driving it
