vw 1.4 75 bhp /100 bhp engine
Discussion
There is the 1.4 TSI "twincharged" unit (which Clarkson hated, btw):
VW said:
The driving characteristics of the new TSI engine are improved over those of the 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 consumption, returning 38.7 mpg on the combined cycle. It also produces impressive torque of 177 lbs ft (240 Nm) from 1,500 through to 4,750 rpm. All TSI engines drive through a manual six-speed gearbox. A DSG automatic option is also available.

Nope, 16v with 100bhp originally in the 16v-badged, sporty looking version of the '94-00 Polo. The engine has done some service, being also in the current model SEAT Ibiza sport (like what I won, yay!). The 75bhp version is also 16v I'm pretty certain, and features in the Mk4 golf. The 1.4 8-valve was only 60bhp, and was fitted to the aforementioned polo and also the Mk 3 Golf. I think. Back to the autism thread for me!!!!!
No idea what the difference is, sorry, though I'd be surprised if it was just in the ECU. I imagine the VW boys would have figured this out by now if so! Post back with your findings....
