What is it?
You do wonder sometimes whether Porsche isn’t a touch too understated for its own good, particularly when it comes to the mid-life revamping of its various models. Take the latest ‘heavily revised’ 997 as an example.
Here is a car which, to the untrained eye, looks all but identical to the original 997 of 2004, yet under the skin it has a brand new range of direct injection flat six engines, not to mention the gearbox Porsche has been threatening to put into one of its road cars for the last 25 years – a road going version of the double clutch (PDK) unit pioneered by Weissach’s Le Mans cars in 1982.
On the surface the only items that telegraph just how different this car is compared with its predecessor are, wait for it, a pair of slightly bigger door mirrors (wow), some LED lights front and rear and, oh yes, a mildly new design of 18- and 19in wheel.
Deeply committed 997 anoraks might also spot that there is no longer a big central radiator to be seen behind the front grille, the new engines being so much more efficient at self-cooling that they no longer require the centrally mounted front radiator of old. But while such styling restraint is actually quite refreshing in an era of increasingly garish fast cars from Audi, Mercedes et al, in this instance you can’t help thinking that Porsche’s designers have undersold the achievements of their colleagues in engineering. Surely a car this new and this significant technically deserves a few more visual cues to prove its point?
No matter, the 2008 model year 997 may well be one of the most unobvious redesigns of the modern era outwardly, but inwardly it’s a seriously impressive piece of work. The big news on the engine front is the fitment of a Bosch direct injection system, which, claims Porsche, improves emissions and economy as much as it does pure horsepower.
The base 3.6 now produces just 225g/km, a 15 per cent reduction compared with the previous model, but at the same time it boasts an extra 20bhp, making 345bhp at 6500rpm in total. The 3.8 unit from the 'S' model jumps 30bhp to 385bhp, and in both cases the cylinder blocks are an incredible 22 per cent stiffer thanks to the fact that there are, says Porsche, around 40 per cent fewer moving parts.
