A great farming tip from the Gameloft Forum:

"Since this turned into a talk about farming and grinding, I have a simple tip that I use to make credits. Whenever I am bored of the game and I'm watching a movie or tv or whatever, I race season 8 elimination s class alps. You get last place and collect 1400 credits in 45 seconds. Useful for a tad of money on the side maybe for some. Frankly I have made half my credits doing this."

So, in the Season 8 - Race 30 the farming stats are:
 * Base Credits: 1,455 Credits (finish in last position: 8th)
 * Race time: 45 sec
 * One playing session (incl. menu clicks & loading times ~35 sec): 80 sec
 * Base Credits / sec (during the actual race): 32.33 Credits
 * Base Credits / hour (incl. menu clicks & loading times): 65,475 Credits
 * One playing session (incl. menu clicks & loading times): 80 sec
 * Playing Sessions / hour (incl. menu clicks & loading times): 45.00

LaFerrari stats (4,745 Base Credits + the accumulation rates) can be found on the Base Credits Accumulation Rate in Season 9 page. On the Season 9 page (Race 55) there's info about the race itself and Vehicles of Asphalt 8 -page is good for quick lookups. The tables are sortable, too.
