The 2nd-generation restyling (to 2018-01-31) and 3rd generation (from 2017-11-01) overlap in the data by calendar; they are different generation records, not one production line.
1 generation (Fastback) runs 2004-10-01 – 2008-01-31 with 5 versions, then a restyling 2008-02-01 – 2011-01-31 with 6 versions. Pre-restyle names: CLS350CGI 3.5 AT, CLS320CDI 3.0 AT, CLS350 3.5 AT, CLS500 5.5 AT, CLS500 5.0 AT. Restyle adds CLS300 3.0 AT and CLS350CDI 3.0 AT (two outputs: 224 hp and 265 hp), keeps CLS350CGI 3.5 AT, CLS350 3.5 AT, and CLS500 5.5 AT, and does not list CLS320CDI 3.0 AT or CLS500 5.0 AT. Every 1st-generation version in the data is RWD, Automatic, 7 gears.
2 generation (Estate 5-door) runs 2010-10-01 – 2014-07-31 with 17 versions recorded (12 named in this extract), then a restyling 2014-08-01 – 2018-01-31 with 26 versions recorded (12 named). Pre-restyle names include CLS350CDI 3.0 AT, CLS250CDI 2.1 AT, CLS250CDI 2.1 MT, CLS350 3.5 AT, CLS500 4.7 AT, and CLS350BlueTEC 3.0 AT. The restyling names CLS250CDI 2.1 AT, CLS350BlueTEC 3.0 AT, CLS220BlueTEC 2.1 AT, CLS400 3.5 AT, CLS400 3.0 AT, and CLS500 4.7 AT. Drive is RWD or AWD. Gearboxes are Automatic (7 or 9 gears) except CLS250CDI 2.1 MT (Manual, 6 gears).
3 generation (Fastback) runs 2017-11-01 – 2022-01-31 with 8 versions, then a restyling from 2021-04-01 (stop not measured) with 5 versions. Pre-restyle names: CLS350d 2.9 AT 4Matic (249 hp and 286 hp), CLS400d 2.9 AT 4Matic, CLS350 AT 2.0 4Matic, CLS300d 2.0 AT 4Matic, CLS220d 2.0, CLS450 3.0 4Matic, CLS350 AT 2.0.
