A couple of months ago, when I ordered the 1.2tsi Yeti, I said I wouldn't look on this site in case there was any news about my preferred 1.4tsi engine coming out. Grr. So I looked back at the stats of the car I've been driving for ten years. Will the techobods on here reassure me that I will feel 'more powerful' with a 1.2tsi? Particularly when overtaking at 30-50mph? Or will the extra weight make them feel the same?

Old car:

Mazda 323 1.5Gxi (only 40,000 miles!) W reg

Engine type: In-line 4 cylinder 16 valve

Kerb weight: 1124kg

0-100kph: 11.9

Max power PS (kW)@ rpm: 88 (65) @5500

Max torque lbft (Nm) @rpm: 97 (132) @4000

Compression ratio: 9.0:1

Ordered car:

1.2TSI SE +Park Assist (inc ESP)

Kerb weight: 1345kg - total weight 1890kg both depends on options

0-100kph: 11.8

Max performance (Bhp/rpm): 105/5000

Max torque (Nm/rpm): 175/15,00-3500

Compression ratio: 10.0:1

I've written the figures down exactly as they are in the manuals - in the Yeti brochure it says all bhp figures are metric and are worked out using a conversion rate of 1.36 of KW figures - these metric bhp figures are otherwise known as PS.

Emissions on the Mazda 185g with a combined mpg of 37.7 in manual (I get about 42) !!! At least that makes me feel better 149g with combined mpg of 37.7 on Yeti.

I'm sure it'll be fine, the significantly higher and much wider torque band should make it seem more powerful, despite the weight.

The Yeti is the car I would have wanted to buy 4 years ago but couldn't (obviously). Funnily enough I bought a Mazda 3 1.6 - 105PS, 103lbf, 40.9mpg, 162g/CO2 (all figures ish). I would be more than happy to swap for the 1.2TSI unit.

"go" is probably similar.

"Stop" should be a lot quicker in the Yeti (ABS, brake assist etc.)

And in a sudden stop (i.e. crash !) I'd much rather be in the Yeti !

I'm sure you'll be more than happy with your 1,2TSI Yeti Try to find out how much torque your mazda produces at 1500 rpm... Your new yeti will be much more flexible, and feel a lot more powerful compared to your mazda

Most normally aspirated Japanese engines need thrashing to get decent performance out of them and as such the quoted figures do not indicate how frustrating they can be to drive. I had a test drive in the 1.2TSI Yeti (having got out of a Japanese engined car funnily enough) and did not find it wanting at all. Relax and ride the (modest) torque wave of a well designed turbo engine

Hi Charlie

as others have said, the Yeti will almost certainly be quicker where it matters: The significant factor is the considerably higher torque, available both in a wide band and from low down in the rev range. ie as you change up a gear the revs will fall, but because of the torque being available at low revs you'll still get pull which will be sustained as you accelerate in each gear. In your Mazda, which requirees high revs to get the most out of it you probably have to drop a gear or two to make it accelerate hard.

When I test drove a 1.2 Yeti there was a moment when I accelerated quiite hard from c.30mph to get to 40mph. When I glanced at the speedo I was surprised to see I'd passed 55!

I really don't think any purchaser of the 1.2 should be dismayed by the predicted avalability of the 1.4tsi. Both engines are very good and share many characteristics and the 1.2 is definitely not underpowered. There are fuller comments on other threads about this.
