Recently read the comparison on Pistonheads between the Macan and the SQ5 and was a little surprised by the power output of the Macan. It stated that the power output was 258 hp which I assume is a "Porsche" tuned version of the Audi diesel used in the current Q5 / A5 etc.
Playing around on various car configurators from Porsche and Audi I saw that the latest Audi A6 has what appears to be a new 3.0 diesel engine and has 272 PS or 320 PS in BiTdi guise. Even allowing for the small difference between PS and BHP the new Audi engines seem more powerful.
Therefore is the Macan diesel based on the older Audi engine which if it is seems a little strange to me for a brand new premium product?
I'm no engineer but this just seemed a little odd.

The Porsche is less powerful.
It uses the simpler and less torquey single blower design.
The Macan uses 7-Speed PDK (which may be the limiting factor) vs the Audi 8-Speed Tiptronic (slush box)

Yep, the Macan is single turbo, the Audi twin turbo. However every review I've read tips the Macan over the Audi, mainly due to the far better chassis setup that Porsche have developed.
Which is partly why I've bought one.... _________________ 1997 993 C2S

Yes I can appreciate the difference between the twin turbo vs single turbo. I was just wondering if the single turbo in the Macan is based on the older gen Audi single turbo unit.
However having sat in one the other day I was hugely impressed and it is definitely on my shopping list when I look to change in a few months despite any engine concerns and waiting lists. Like the SQ5 but like the Macan more.

Not sure why it's odd, Audi have only released their new BiTDi engine which sits in the A6, it takes time for engines to filter down across all of the ranges, as it's not as simple as just adding a new engine that someone has released, since it may work in a Audi but may not work in a Porsche.
This new BiTDI is probably the cards in the Porsche range but engines need to be tested, tuned to their own spec, designed to fit in the car and the production facility within their own manufacturing schedules, as well the knowledge, technology and parts filtered down to the global dealer network.
But is it wise to be so interested in diesels when air quality directives may compel the government to load the tax regime against them over the next few years _________________ Colin
