New giant Cave lion skull from Romania. However, its given measurement is not really accurate.

Does anyone remember or have on hand cave painting of the cave lion that depicted striping?
Yeah, I do remember the cave painting that featured the striped Cave lions.
Since this group of lion is most distantly related to the modern African lion, even more than the Cromerian lion/American lion lineage. They were also convergently evolved toward the tiger species, but they still belong to the lion lineage nevertheless. 
if the cave lion was not a sub species of lion does that mean they lived with p leo in europe side by side

Although the Cave lion wasn't a subspecies of the African lion like the Asiatic lion, but they still belong to the lion lineage, since the lion lineage isn't only exclusively limited to Panthera leo, but with several other lion species as well. The Cave lion is probably the earliest offshoot of the lion family, they probably split from the African lion even earlier than the American lion, since the American lion resembles to the African lion much more than to the Cave lion.

The modern lion (P. leo) entered Europe after the extinction of the cave lion. You can consider the product of niche. Despite P. spelaea having a good amount of size over its modern relatives, the prey species size was not different enough for P. leo to deal with the physically superior P. spelaea as competition. This is likely the same reason the tiger did not extend into the Caucuses until relatively recently.
Those non-leo lion species and non-tigris tiger species are fascinating. Hopefully there will have more uncovered fossils on these extinct felines.
The Asiatic lion and the Barbary lion straightly came from the African lion back in 100,000 years ago. I wonder if some of them managed to find a way into Europe before the extinction of the Cave lion.
@GrizzlyClaws, do you have the paper at hand for the lion subspecies dates?
I don't have an elaborate scientific paper available right now, but it is the common knowledge that the Asiatic lion along with its close relative the Barbary lion evolved from a group of migrated African lion back in 100,000 years ago.
Regarding my earlier inquiry of the striped cave lion cave art. I asked such as the discovery of the cave lions cubs, which had no pattern. So, were the ancient people seeing the same species as the cubs?
I can't seem to find the striped lion cave painting online, which is frustrating. Does anyone have any clue where we could find it?  
The Biggest Saber Cat
A fossil skull from China represents one of the largerst saber-toothed carnivores of all time By Brian Switek on November 3, 2016 Top view of the Machairodus horribilis skull. Credit: Deng et al., 2016.  *This image is copyright of its original author Sabercat is practically synonymous with Smilodon. Fossils of the famous knife tooth have been found by the hundreds in the La Brea asphalt seeps of Los Angeles, and the South American species – Smilodon populator – was one of the largest sabertooths of all time, the largest of which were bulkier than a tiger. But as far as skulls go, at least, Smilodon can’t lay claim to the Biggest Sabercat superlative. That honor goes to a different carnivore. Paleontologists Deng Tao, Zhijie Tseng, and colleagues set the record straight in a new paper all about a huge skull of Machairodus horribilis. The fossil, found in the roughly 8.3 million year old rock of China’s Longjiagou Basin, is a little bit crushed. Time and the caprices of geology have squished the cheeks and wide frontal bones of the skull into a much narrower profile. Reconstructed to its shape in life, however, the cream-colored cranium represents a menacingly large sabercat. The new Machairodus horribilis skull measures over 16 inches long. That’s not only longer than all other known skulls of contemporary sabercats, but also those of the Ice Age celebrities Smilodon and Homotherium. That translates to an estimated body mass of over 892 pounds for this particular Machairodus horribilis, putting it in the same range as the burly Smilodon populator. However you care to slice it, this was one big cat. Views of the large Machairodus horribilis skull. Credit: Deng et al., 2016.  *This image is copyright of its original author It would be a mistake to treat Machairodus horribilis just like any other sabercat, though. While the feline shared the long, serrated fangs and other modifications seen in its relatives, for example, Deng and colleagues point out that Machairodus horribilis had a relatively small gape. The cat could only open its mouth about 70 degrees, comparable to what modern lions are capable of, rather than the ludicrous 120 degrees Smilodon could achieve. Along with differences in muscle attachments, the paleontologists write, this means that Machairodus horribilis may have targeted relatively smaller prey than later sabercats tackled. Machairodus horribilis comes to us, then, as something that was neither like modern cats nor like later sabercats. Its thin canines would have dictated a targeted throat bite, yet the limitations of its muscles and gape likely limited the size of its preferred prey to a narrower range. To cut it short, big predators did not always pounce upon even larger prey. Reference: Deng, T., Zhang, Y., Tseng, Z., Hou, S. 2016.

A skull of Machairodus horribilis and new evidence for gigantism as a mode of mosaic evolution in machairodonts (Felidae, Carnivora) Deng, Zhang, Tseng & Hou, 2016
 *This image is copyright of its original author Abstract: "Sabertooth cats were extinct carnivorans that have attracted great attention and controversy because of their unique dental morphology representing an entirely extinct mode of feeding specialization. Some of them are lion-sized or tiger-sized carnivorans who are widely interpreted as hunters of larger and more powerful preys than those of their modern nonsaber-toothed relatives. We report the discovery of a large sabertooth cat skull of Machairodus horribilis from the Late Miocene of northwestern China. It shares some characteristics with derived sabertooth cats, but also is similar to extant pantherines in some cranial characters. A functional morphological analysis suggests that it differed from most other machairodont felids and had a limited gape to hunt smaller preys. Its anatomical features provide new evidence for the diversity of killing bites even within in the largest saber-toothed carnivorans and offer an additional mechanism for the mosaic evolution leading to functional and morphological diversity in sabertooth cats."
