L320 Diesel Engines

Best L320 engine - 2.7 L TDV6 (Ford Lion V6 )

Best L320 engine - 2.7 L TDV6

The PSA (Peugeot Société Anonyme) and Ford partnership produced the 2.7 L TDV6 engine used in the Range Rover Sport. Through this relationship, the engineering skills of both companies were combined to create an engine that offers reliability, efficiency, and power.

Of course, it might not be as enticing as the other engines in the lineup and is regarded as an entry-level engine. This V6 engine that was in production from 2005–2009 has a 2.7-liter displacement. While it is fuel-efficient, it lacks the torque that a performance sport utility vehicle should have. 

But don’t let the indirect disclaimer above mislead you. The sophisticated turbocharging mechanism in this motor improves power delivery and minimizes turbo lag. Pedal to the floor will still pin you back to your seat.

The engine can endure well over 200,000 miles if it undergoes regular servicing.

Despite the reputation that the 2.7 L TDV6 engine has for dependability, some owners have complained about problems with their turbochargers, EGR (Exhaust Gas Recirculation) valves, and coolant leaks.

2.7 L TDV6 Reliability

Owner experiences are the greatest way to determine an engine’s reliability. The engine has received great marks for durability from several Range Rover Sport owners, who have reported engines achieving high miles without significant problems. 

The vast majority of owners, meanwhile, assert that owning this engine has not been a particularly enjoyable experience. And for a worthy reason.

See, crankshafts on the 2.7 snap quite unexpectantly. The TDV6 crank is not well-designed. The webs between the journals in the crankshaft are far too thin for the power and torque that the tdv6 generates, which could be a design error or manufacturing blunder.

If the crankshaft doesn’t snap, you may also experience engine failure due to twisted bearings and bearing knock. 

The oil pump also deteriorates over time, cutting off flow to important elements such as the crankshaft stated above, which could result in engine failure.

Is this the best engine for the L320 Range Rover Sport? Our conclusion is…
