BMW M4

Car looks great, does the M3, however my understanding is the engine has a few tweaks over the 335i/135i/235i engine - namely in the form of reinforced cylinder heads and a few odds and sods. It's a shame that the engine isn't as special as the V8 though :(

Its a lot more than that,
Some quotes below:

Among the technical highlights for the new BMW M division engine is its closed deck design for added rigidity. It also uses a spray coating instead of traditional cylinder bore liners for reduced weight. A forged crankshaft is also used for reduced rotating masses, which in combination with lightweight pistons......

.....Despite the similarities in specification between the new M3 and M4's engine and that of the earlier 1-series M coupe, Biermann, reveals the two engines share little apart from their bore and stroke measurements. "They are completely different, not only in construction but internally and their respective induction processes," he says, adding, "They're worlds apart......

......W's M division engineers have mounted the water-to-air interooler system for the turbochargers atop the engine instead of out in front, justifying the inclusion of a prominent power dome within the bonnet. Unique features such as a magnesium sump ensure the new engine weigh 22 pounds less than the naturally-aspirated 4.0-liter V8 direct injection gasoline unit it supplants at a claimed 452 pounds....

Realistically how much is an M135i lease per year for 15k miles and more importantly the right spec? Auto please.

This is what I came up with. I can find sub £400 per month quotes for the M135i with standard spec, I can't find anywhere that will quote me with a changed spec.
My configuration: http://mybmw.co.uk/l0q4o7s2
On the road cash price £40,225

Meh, standard spec with the 8spd ZF & Metallic paint does me just fine.

Forced into not having any options, but I certainly don't miss any of these packs. I'm sure cruise would be nice for long journeys, but that's about it.

I use my Nexus 5 with free Google Nav in a Kenu mount, which does the job perfectly. No need for an £1800 Nav option. Music taken care of by an ipod/usb stick plugged into the USB in the central armrest.

Loving the new M3 in the baby Blue colour, but the M4 just looks a little bland. I'm sure I'd enjoy driving one, but I doubt it's different enough from the M135 to make it worth the significant price difference. They are both already too fast for the public roads, so handling would be the deciding factor. But with it also having electric steering, I very much doubt it'll 'feel' any different as there is no feel to start with :p

No matter how you dress it up, it is still a Straight 6 and will sound like one. Yes it might provide better MPG and lower the tax bracket a bit, but you don't buy a BMW M3/M4 to be frugal. Maybe I am a bit of a luddite here, and the conversation we'd be having would be different if 6 cylinder technologies had come on far earlier than now.
 
I only have no idea what you are getting at its probably the most advanced straight six ever to be honest? And only a straight six? You realise most m3s have had straight sixes?

So what? BMW are reknowned for Straight Six engines. It's hardly a travesty, infact in the entire history of the M3 only one has ever had a V8. The BMW Straight Six is an iconic powerplant, its hardly as if it's just got a turbo four, is it?

Plus I hear that the turbo six can provide zero cost motoring ;)
 
E30 = I4
E36 = I6
E46 = I6
E9x = V8
F80 = I6

The only way the m3 would have more v8s than i6s is if you were to count the e9x series as individual cars and not just numerical designations for body styles, right? And even then it wouldn't have had more v8s, it would have had the same number of v8s to i6s.
