New 156 2.4 JTD 20v - It's mind blowing
You may have picked up from a previous thread that I have just taken delivery of my new 156 2.4 JTD 20v veloce sportswagon.
I've driven only 300 miles so far as the weather has been bad and I have been trying to keep the beautiful Alfa red paintwork out of the salt on the roads wherever possible. I also went for the spoked 17inch wheel option and they too look great.
The engine feels very tight and I've only used upto 4000 rpm once it's really warm and just for the odd occasional burst.
All I can say to any petrol revving cynics out there (and believe me, I was one for many years) is that the tide has finally turned and this engine really will put the Alfa diesel on the map once and for all.
I will simply say this, my previous 156 2.5 V6 feels totally slow in comparison and almost gutless. Honestly, this really is the case.
The 20v JTD has got so much grunt between 2000 - 4000 rpm that you struggle mentally to try and work out how they have actually done it. Also the map for the turbocharger boost and the cam timing with the 20v's has clearly been calibrated to give you a continued surge/build up of torque/power right upto 4000 rpm, which makes it feel more like a petrol engine in the way it revs.
The stats for the engine are 284lb ft at 2000 rpm and 175bhp at 4000 rpm which also confirms the "revvy" feel" charcteristics of the engine.
Some previous diesels I have driven pulled well but seemed to "run out of puff" and feel flat after about 2500rpm but this one just keeps pulling all the way upto 4000rpm then flattens off gently.
It's so deceptive as by the time you get to 4000 rpm you are already doing an outrageous speed or have hurtled by other slower moving traffic. You just seem to ride on a great big wave of torque that just keeps going and going. You have to watch the speedo carefully as it catches you out.
The engine is also very quiet. Much more refined than the 10v and you would struggle to tell it's a diesel at most speeds. Start up is also very refined.
Have to agree with Rick from a previous thread that the 5 cylinder engine does sound like the old Audi Quattro Turbo rally car and at medium revs it really does sound great, a kind of aggresgive warble that is very addictive.
Economy so far has been between 29 and 41 mpg, but to be quite honest that is just a bye-product bonus for me right now.
A cliche I know but having had some great petrol Alfa's and dare I say it a few quick BMW's, this 156 is the new benchmark in my opinion.
The JTD will honestly have the measure of many supposed sports cars on point to point journeys. On the track flat out I might be tempted to take the 156 GTA for it's high revving bhp but the JTD would be right up there gunning for it.
I'd be interested in other owners comments.
