Now racked up 400 miles in this 318d ES, and had time to form some impressions.
Dropping from SE to ES spec, you lose some rather nice bits of kit, it has to be said. The fancy dual zone climate control panel is replaced by a rather cheap looking, albeit perfectly functional conventional heater / air-con system. Cruise control disappears too (not that I ever used it), as do the rear parking sensors, rain sensing wipers, auto lights, and the cool, ice blue puddle lights under the exterior door handlles. The nice 17" alloys have also gone, replaced by much more plain looking 16" affairs, with skinnier 205/55 section tyres. This particular example is also black, which I don't think does the E90 shape any favours at all, personally.
All this was initially a little disappointing, given that most of it smacks you in the face within seconds of, if not clapping eyes on the car, then at least wandering around it. It looks and feels cheaper than the older SE, not just in kit terms, but things like the "leather" of the gear lever and handbrake gaiters which is clearly now PVC, and the steering wheel rim which feels skinnier and has a different texture. Despite the same flawless quality of the interior, it very much feels like the 'bargain basement' spec model that I suppose it is.
Thankfully, it gets better on the move. Much better, in fact. First thing you notice is the far superior ride quality offered by those skinnier, higher profile tyres. While the other car rode well enough, it was always on the firm side of comfy. In the ES, there is no crash or thump over the notorious "third" sleeping policeman on the drive up to the office, and on the rutted Surrey B-roads outside, it feels supple and planted. Gone is the fidgeting and tramlining from the nose over awkward cambers, and the constant thumping from the suspension. It flows better, somehow, almost feels lighter on its feet, even though it probably isn't. Smaller is definitely better when it comes to wheels on a BMW.
If there's any handling penalty for the "heavy" diesel lump, I haven't found it, although a peer under the bonnet sees the engine rammed hard back against the bulkhead and well behind the front axle line. Turn in is still instantaneous, the tail still beautifully 'alive' when you're in the mood (more so thanks to greater torque and skinnier tyres), and the better ride afforded by the smaller wheels actually makes this the preferable of the two cars to drive hard, in my opinion. The steering is also heavier than the petrol version, and while this doesn't really endow it with any more feel, does somehow give it a more reassuring, substantial feel when pressing on. The wonderful accuracy and zero slack of the petrol version's steering are both carried over unspoilt.
And to the engine, which has a transformative effect on the experience compared to the 318i petrol unit that eclipses all the above by some margin. Quite simply, it's a belter of a unit. Gripes are limited to two areas. Firstly the rumbly, "unmistakeably diesel" note, and "boom" at 2200 RPM, are both a football field short of the refinement and decorum of a Renault common rail diesel from best part of a decade ago. Secondly, there is a bit more turbo lag than I was expecting, especially compared to the VAG PD in our mk4 Golf, with a perceptible delay between asking for power, and getting it.
That really is it on the whinge front though, because it's a corker of a unit. One of the smoothest, gutsiest diesel engines I've ever driven with a range of useable punch all the way between 1500 and 5000 RPM. Prod the accelerator, and it simply lobs the car up the road with a smooth, sustained lunge. While it's no land speed record breaker, neither does it ever feel underpowered. Laden, unladen, uphill, downhill, it just goes when you ask it to. It is also one of the best motorway cruisers I have experienced. 70 mph in 6th = 1750 RPM, and there's still enough torque to accelerate you reasonably swiftly, or pull you effortlessly up a hill. Very long legged, and with less road noise and a smoother ride than the other car (those wheels and tyres again)
Haven't refuelled yet, but computer suggests a 46.3 mpg average so far on this tank. Given the way it's been driven, and some of the traffic conditions encountered, that's a pretty impressive figure. Assuming it's even half accurate, the car should be easily capable of well over 50 mpg with more gentle use.
I look forward to driving it for the next couple of months.
