I spent the day at the Roswell, Georgia, BMW dealer with my friend S as he shopped for 7-Series BMWs and I must lodge a complaint as the owner of a 2001 BMW 530i “e39″ with a 3 Liter inline six motor.

The complaint is based on the two numbers after the series number of each car. For example, in the past, a 750i had a 5 Liter engine, a 328i had a 2.8 Liter engine, and the 318i had a 1.8 Liter engine. The engine displacement has always been kept in the two numbers after the 3, 5, or 7 Series number.

Now, as we test drove a 2011 BMW 740Li and a 750Li I discovered that the 2011 528i has my car’s engine, a 3-Liter inline-6, and is just sporting the 28 “out of tradition.” What? What’s more, the 740Li sports a twin-turbo 3 Liter 6, not a 4-Liter, and the 750Li sports a 4-Liter 8 and not a 5-Liter!  Even more, the 2011 BMW 335i is a 3-Liter inline-six with a twin-turbo and not a 3.5 Liter engined car.

The first thing the dealer did when we shot off in the 740LI was, “doesn’t feel like a six, does it?”  The tail doesn’t at all designate that the traditionally and historically naturally-aspirated award-winning BMW engines are now often turbo and twin-turbo-assisted, though this is not represented in the new alpha-numeric nomenclature.  Since “i” means fuel-injected and “x” means all-wheel-drive and “L” means long-wheelbase, shouldn’t “t” mean turbo or “b” mean biturbo?

Am I silly or are you as appalled as I am?

BMW‘s official unveiling ceremony isn’t until Monday, but a few authentic shots of the all-new “F10″ BMW 5 Series are floating around cyberspace. These three low resolution images only give us a frontal glimpse of the upcoming 5 Series sedan, apparently as it does a dress rehearsal for its big show at the beginning of the week.

Our first sans-camouflage observation says it looks much like the 5 Series GT, its close sibling (nobody was expecting any radical styling departure anyway). Thanks to its “sport sedan” role, the new 5 Series four-door sports a slightly more aggressive flair to its front facade and side styling.

In case you were wondering, the little black buttons just ahead of the front wheels are side view cameras, just like those found on the 7 Series. We’ll reserve further judgment until Monday, when they pull the rest of the tarp off. Thanks for the tip, Brandon!
