The future of the naturally-aspirated V8 is something of a bone of contention within Porsche at the moment. So that makes the 4.8-litre second-generation Cayenne GTS potentially very special indeed; one of the last - or maybe even the last - Porsche V8s unencumbered by turbo plumbing and lag.
Mind you, it's only when you drive the most road-oriented model in Porsche's Cayenne SUV range that you understand its stablemate Turbo has lag after all.
Hit the GTS' throttle and the response comes NOW. In the Cayenne Turbo it's now followed closely by HOLY MOTHER OF GOD!
