Welcome to this new episode of BMW Today. Fasten your virtual seatbelt and hit the road with the source of joy: The all-new BMW 4 Series Convertible.
The standalone body design has dynamically stretched proportions and a low-to-the-road silhouette. Expressive front end brings together tradition-rich and modern styling features. The prominent, upright BMW kidney grille references legendary sports cars from the brand’s past and signals the high cooling air requirement of the powertrain technology. Extremely slim LED headlights are standard, BMW Laserlight optional.
The newly developed panel bow soft-top roof marries the strengths of a retractable hardtop and the puristic appeal of a fabric hood, thereby combining the best of both worlds: its sleek surface gracefully arches over the passenger cell of the new BMW 4 Series Convertible and is 40 per cent lighter than the roof of the predecessor.
Carefully modified chassis geometry, mounting and set-up for added agility, precision and dynamic prowess make sure the new BMW 4 Series Convertible packages driving pleasure in a particularly exclusive form..Specially tuned lift-related dampers as standard, even stiffer M Sport suspension including variable sport steering are available as an option.
Inside the new BMW 4 Series Convertible, four seats and a modern, premium setting create a ticket to sporty driving pleasure combined with the allure of exclusive open-air motoring. The structuring of the equipment lines likewise reflects the shift in focus to dynamic performance that characterises the new model generation. And the new models offers a far wider range of driver assistance systems.
The all-new BMW 4 Series Convertible. Enjoy every edge.

in this video we’re going to be discussing what happens when an engine has no oil. As a demonstration, we’ll be viewing an engine with and without oil running. This is the exact same engine on the left and the right, on the left with oil, and on the right without. Both engines will start at the exact same time, but the video on the right was filmed 24 hours after the video on the left, allowing for the engine to completely cool. This is a 212 cc air-cooled single-cylinder Harbor Freight engine.
There are five points we’re monitoring on each engine. Point one is the crankcase, below the level at which oil will rest. Point two is the top of the crankcase, where there obviously won’t be any oil resting near. Point three is the air-cooled cylinder bore. Point four is the exhaust pipe exiting the cylinder before entering the muffler, and point 5 is the valve cover. This is a pushrod style valve train with overhead valves.
Opening the crankcase reveals the permanent damage which occurred. First of all, look at the small amount of oil that didn’t quite make it out while draining. It’s quite dark, and this is after a 15 minute run with oil, and 15 minutes without, in a brand new engine. The oil which remained in the drained engine is clearly quite dirty, and actually it has quite a bit of metal content in it, as you can see reflecting as I move around the towel.
Examining further, I removed the connecting rod cap from the crankshaft. This is the bearing the crank rotates on. You can see the scored, less reflective surface of the cap. Indeed, you can see the scratches on the crankshaft as well. I would expect to see similar issues with the camshaft and cylinder bore as well.
