Is the modern-day BMW sport coupe too big and heavy to be sporty?

I understand your point about performance cars and weight, craig, but having recently finished a stint in a 2015 Challenger Scat Pack Shaker (https://bit.ly/1O9b9o2), which was brilliant fun but also an unwieldy beast, plus I've also driven many other SRT-tuned Challengers over the years, once doing circles around Willow Springs back to back which was followed up by stints in SRT-tuned Chargers that were much better balanced, I wouldn't want to use it as an example of an ideal road car, even with the Hellcat's extra power. It's also half the price of the M6, so less is expected. As for the Model S, it's a big sport sedan and a lightweight compared to some brilliantly balanced Bentleys I've enjoyed, but probably not the best comparo to a BMW sport coupe either. I think we're all in agreement regarding the E9, a car that still drives wonderfully, while I'm also a big fan of the E31 stylistically, but by BMW standards it truly was a pig to drive in stock trim. BMW now owns a carbon fibre plant currently used for its i3 and i8 (and possibly M coupe roofs and other trim bits, I'm not sure), so its quite possible we'll see much lighter M super coupes in the future. Let's keep our collective fingers crossed...

Considering the Dodge Challenger Hellcat weighs in at 4469 lbs., and the Tesla Model S weighs 4647 lbs., it may not be out of line. I, for one, do miss the 1990's E31 8-series, as it was a true pillarless hardtop, as was the earlier E9 2800CS/3.0CS.

Of all the BMW cars, the 6 series is my least favorite. While its styling is very appealing, the car has always felt ponderous. I prefer the lighter cars much more than this BMW.

I'm not a fan of how much BMW's have grown in size. Thank goodness for the 2-series, and it's more sensible proportions. That said, even that has grown in size over the 1-series it replaces. I realize that BMW has worked hard to reduce weight, increase power and efficiency, but enough is enough already! The 6-series is a boat, the 3/4-series is the size of the old E39 5-series and the 2-series is the size of then E36 3-series. When is the madness going to end? With as advanced as technology has come with regards to manufacturing, why hasn't anyone come up with a way to have a car with the size, weight and greenhouse of older cars like the E9, E30 and E28? BMW cabins have become so isolated from the world outside that engine sounds have to be piped in, and cameras and blind spot monitors have to be added because outward visibility is so poor.

A double-edged sword really isn't it. On the one hand, today's performance M series BMW's offer a level of build quality, technology and safety features earlier models such as the 8-series could only dream about yet at the same time, offer a digital driving experience compared to the analogue experience of say a classic E24 M6 . Also on the minus side for today's driving enthusiasts, the modern models do feel their extra weight and lack the scalpel sharp precision, nimbleness, feel and sheer delicate balance that BMW built their reputation on. If I were to buy a new BMW today, my ideal choice would be for the rare and discreet Alpina variants. Certainly in Europe, these combine the perfect blend of increased, discreet mechanical and visual muscle and the proverbial "dream car garage" would also include some classic BMW's such as the M1, 3.0 CSL, M3 Sport Evolution, E28 M5 and Alpina's such as the E24 B7, B6 3.5S and B12 5.7 coupe. Still, that's not to take anything away from the current BMW offerings, no question they have a lot to offer on several levels, you simply pay your money and make your choice based on your personal preferences, taste and priorities.
