Browse 2014 Mercedes Engines by Model
Match your 2014 Mercedes engine by vehicle. Use the cards below to identify the right chassis Type code — every unit is then VIN-matched at the order step. Not sure which Type code you have? Text us your VIN and a specialist confirms the match.
2014 E Class
212 Type sedan/wagon and 207 Type coupe/cabrio: E250 2.1L diesel, E300, E350 3.5L (RWD/AWD, gas and flex-fuel), E400, E550 4.7L, and the 5.5L E63. The widest 2014 line — check the Type code first.
2014 C Class
204 Type in its final full season: C250, C300, and C350 in sedan and coupe, RWD and AWD. One C350 sedan is a flex-fuel unit — confirm before ordering.
2014 S Class
222 Type S550 (RWD/AWD) and the S63. The W222 generation's first year; do not cross-shop with the outgoing 221 Type.
2014 SL Class
231 Type SL550 roadster. Note: several units cataloged under the SL line are 222 Type S-Class engines — trust the Type code over the badge.
2014 SLK Class
172 Type: SLK250 in both manual and automatic fitments, plus the SLK350. The manual SLK250 is a genuinely rare pull.
2014 CLS Class
218 Type: CLS550 in RWD and AWD, plus the CLS63s. Four-door coupe bodyshell, distinct mounts from the E Class.
2014 CL Class
216 Type CL600 and CL63 — the CL's last model year before the S-Class coupe rename. Low-volume V12 and V8 units.
2014 CLA Class
117 Type: CLA250 in FWD and AWD, plus the CLA45. VIN 6th and 7th digits separate the three fitments — 4E, 4G, 5C.
2014 G Class
463 Type G550 and G63. VIN 6th and 7th digits (3H / 7D) are the only reliable way to split these two.
2014 GL Class
166 Type across the full ladder: GL350, GL450, GL550, and GL63. The GL350 is the diesel — verify fuel type before you order.
2014 GLK Class
204 Type: GLK250 plus GLK350 in RWD and AWD. Shares the 204 chassis code with the C Class but the engines are not interchangeable.
2014 ML Series
166 Type: ML350 in gasoline and diesel, ML550, and the ML63. The gas/diesel ML350 split is the most common fitment mistake on this line.
2014 B Class
The Electric Drive year: 242 Type (electric, US market) alongside the 246 Type B250 gasoline unit built for the Canada market.
Why Buy a 2014 Mercedes Engine from Auto Power Source
Every 2014 Mercedes engine in this collection is inventory-verified against its donor VIN before it is listed, then held in our climate-controlled warehouse pending sale. Each unit clears our six-step inspection — VIN-matching, ASE testing, noise & smoke verification, full visual inspection, multi-angle photography, and palletized shipping.
2014 is a transition year for Mercedes, which is exactly why the Type code matters more than the badge: the 222 Type S Class replaces the outgoing 221, the CL is in its final season before the S-Class coupe rename, and the B Class arrives as an Electric Drive. Our ASE-certified technicians compression-test every cylinder and run a leak-down evaluation before any 2014 Mercedes engine is cleared for sale. You pay a fraction of dealer-new pricing for identical Mercedes engineering, ship free on a heavy-duty pallet anywhere in the continental U.S., and get up to a 3-year warranty plus 30-day money-back. Not sure which 2014 variant fits? Text your VIN and we will confirm.

2014 Mercedes Engine Buying Guide
-
Start with the chassis Type code, not the badge. 2014 Mercedes catalogs engines by Type — 212 and 207 both wear an E badge, 204 covers both the C Class and the GLK, and 166 covers both the ML and the GL.
-
Read the VIN 6th and 7th digits. This is what separates the 2014 CLA250 FWD (4E) from the CLA250 AWD (4G) and the CLA45 (5C), and the G550 (3H) from the G63 (7D).
-
Confirm fuel type on the ML350 and GL350. Both 166 Type units ship in gasoline and diesel for 2014 — this is the single most common fitment mistake on this year.
-
Match drivetrain and body style. The 2014 E350, C350, CLS550, GLK350, and S550 each ship in RWD and AWD; the E Class also splits sedan, wagon, coupe, and cabriolet across two Type codes.
-
Watch the flex-fuel and market variants. Several 2014 E350 and C350 units are flex-fuel (E85), and the B Class 246 Type B250 is a Canada-market gasoline build — they are not interchangeable with their US gasoline counterparts.
Our ASE-certified technicians verify every one of these points against your VIN before any engine ships.
