The latest engines have a form of VTEC, IIRC.
Which would explain the torquier delivery.

If I remember correctly, the 2007 onwards Boxster uses the newer 997 engine, the same as the Cayman, just not bored out as much as the 911's, you can even use the X51? performance pack on the Cayman Engine.
Both the Boxster S and Cayman S are quoted as 295hp, 3.4L

295 HP equals 291 BHP I think???

The old 3.6 litre lump in my 993 has a distinct, almost-VTEC like changeover at 3,000 rpm when there's a perceptible increase in torque and acceleration. I'm not sure if Porsche has a name for it, a la VTEC
(My 993 is a later model with the Varioram engine, but I confess I'm not sure what the difference is from the earlier non-Varioram models. I think it's also distinct from Variocam, which featured in the 968 and other engines)

Enjoyed Clarkson's likening the front LED sidelight/running lights to that of Christmas lights on a council house.
Audi used Goodwood as a venue for launching the car, & I noted even the most hardened blase office staff & marshalls were impressed & gave them more than a cursory look.
The models in Inevitable Silver did not gain half as much attention as versions in white and black.
Ignoring the still girlie TT, & with the much improved A4 & sporting derivitives, buying Audi begins to look like an informed intelligent choice when all the world seems to be unable to look beyond 'other' German brands.

Variocam is what you had; it's a vernier timing advancer on the inlet cam wheel.
Alfa Romeo, M-B & A-VTEC have a similar device.
Varioram's when you change the length & harmonics of the inlet tract, in order to boost low down torque, which is crap on 6-cylinder engines. It's like the system on NSXs and Preludes.
With the latest 3.4, they have a variable lift system similar to old i-VTEC. So all three, in fact.

Porsche wins again and Clarkson talks shite as usual, could have predicted the tone and outcome every time.
