So I'm a long-time reader of this forum, but not much of a contributor
I'll be hunting for a GT in about a month's time to replace my E36, a stop-gap after a very pricey (and doomed) affair with a Rover Coupe - I've had literally no problems with the Beemer, but I want another Alfa.
Now, from what I've read on here the JTS engine is to be avoided, as it seems the power gains aren't worth the potential expense from carbon build-up, injector trouble, etc. The JTS GTs over here are quite cheap though, compared to the Twin Spark-powered GTs, due to our extortionate road tax. It was the same with the 156 - the 1.6 seemed to be the most popular over here.
...So I think I'm going to go for the Twin Spark again - it has so much character anyway, and I know the ins and outs of it, so I know I won't regret it. It's kind of pleasing to know that the GT seems to be the last Alfa to have one, too.
I'm not at all interested in the diesel, and I can't afford the V6 - as much as i would love it!
My question, and apologies that I took so long to get to it, is this:
Why does the Twin Spark-powered GT seem to be down a bit performance-wise on my old 156?
From researching it on various sites, the figures seem to be that bit worse. Here's an example, from Parkers:
- My old 156's stats
Alfa Romeo 156 Saloon (97-05) 1.8 TS 16V S1 4d - MPG, Dimensions & Performance | Parkers
- The GT
Alfa Romeo GT (04-10) 1.8 TS Cloverleaf 2d - MPG, Dimensions & Performance | Parkers
It seems the GT is 60kg heavier, but that can't be too significant. It also seems to have slightly less power and torque, and is apparently more than a second slower to 60mph - and loses a bit off the top, too.
Is it to do with the Euro Emissions Standard rating? Have they strangled the GT's performance to make the tree-huggers happier, or is it something else?
