Hyundai Lambda I 3.3L MPi (G6DB)

The 3.3L MPI Lambda engine is a lightweight, powerful and efficient small-block found in cars like the Hyundai Accent or Sonata!

It has been specifically designed with an aluminum open deck block for added strength and four valves per cylinder paired up to two overhead camshafts on each side of the bank, which make it perfect if you want low emissions but still lots of power under your feet. 

The intake and exhaust valves on the G6DB engine are actuated via solid buckets. In this case, adjustments need to be made every sixty thousand miles. However, headcovers for cylinders make up its aluminum body.

There’s also a multi-port fuel injection system with conventional spraying methods used by nozzles into the intake ports during the combustion process. 

An innovative plastic manifold that ensures even distribution throughout vehicle assembly.

The engine has a power rating of 244 HP at 6,000 RPM and 228 lb-ft of torque at 3,500 RPM. 

Applications of G6DB engine: 

  • 2006 – 2008 Hyundai Azera 
  • 2007 – 2009 Hyundai Santa Fe 
  • 2005 – 2008 Hyundai Sonata

  • 2005 – 2009 Kia Sorento

Hyundai Lambda II MPi (G6DF)

The 3.3L MPI Lambda II engine appeared in 2009. It was a vast improvement over its predecessor, allowing G6DF engines to increase their maximum output performance while being more environmentally friendly at the same time.

The dual CVVT – variable intake/exhaust valve timing can be easily distinguished by looking for new cover designs on both parts and plastic head covers that come with the Lambda cylinder heads instead of metal ones like before.

The 3.3 Lambda II MPi engine can produce 266 HP at 6,400 RPM and 234 lb-ft of torque at 5,300 RPM.

  • 2010 – 2012 Kia Opirus
  • 2014 – 2020 Kia Sorento

Hyundai Lambda II GDi 3.3 (G6DH and G6DM)

The Lambda 3.3 GDI version started its production in 2011. This modified engine has a streamlined design that makes it efficient and powerful.

It still retains the same four valves per cylinder (two for both intake and exhaust) but with no hydraulic cam followers or follower mechanisms to reduce weight compared to older versions when they were equipped with both features. 

The chain-driven variable displacement oil pump allows for quick-revving, so drivers will never have any problems keeping up on their driving skills while enjoying all-day cruising without worrying about getting tired out too quickly because of its lower RPM range which promises better gas mileage than before since there are less moving parts.

The engine is a gasoline-powered, two-cycle machine. It has one high-pressure pump that resides on top of either the front or right cylinder head. It provides up to 2176 psi maximum pressure from its fuel injection system via an additional cam-driven off exhaust camshaft timing at prescribed intervals during operation. 

That change helps provide greater efficiency and quicker response time when you need your vehicle’s power.

The electronically controlled direct injectors spray compressed fuel into the combustion chambers directly for an efficient and precise process. Due to its power, Hyundai Lambda 3.3 GDI engines are installed on large SUVs or crossovers.

The Korean manufacturer sport this technology in luxury goods like Genesis along with other cars. 

The Lambda 3.3 GDI produces 290 HP at 6,400 RPM and 255 lb-ft of torque at 5,200 RPM. 

Applications of Lambda 3.3 GDI (G6DM and G6DH): 

  • 2011 – Present Hyundai Azera 
  • 2012 – 2018 Hyundai Santa Fe 
  • 2013 – 2018 Hyundai MaxCruz/Santa Fe XL/Grand Santa Fe
  • 2011 – 2021 Kia Cadenza

Hyundai Lambda II RS T-GDi

The most powerful, advanced, and high-performance engine in the Lambda lineup is the 3.3 T-GDi Lambda II, technically addressed as the G6DP engine. This engine is all aluminum, with two direct-injected twin turbos initially launched in the 2016 genesis G80 and the Kia Stinger after a year. 

With new cylinder heads equipped with water-cooled exhaust manifolds, the engine upgraded its cooling system. The engineers installed sodium-filled valves and increased flow through these features of this component for better efficiency during combustion by providing more power at higher RPMs. 

The upgrade also includes the integration of an electronically controlled thermostat for precise temperature control. 

Like the newest model of the G6DH, this engine has a new turbo engine that’s more powerful than its predecessors. The high-pressure direct injection system works at 2,900 psi maximum due to increased fuel demand.

The turbocharged V6 in the new Genesis features two turbos located at opposite ends of each cylinder bank fed by high-pressure injection with a 2,900 psi maximum operating pressure, thanks to its direct fuel system. 

There are two single-scroll turbos with electronic wastegate actuators for improved response time in each cylinder bank which results in better power delivery during acceleration while also being able to provide great efficiency by reducing emissions levels altogether.

A boost air charge comes first through a catalytic converter before being cooled on-board via air intake systems, including heated ducts near your ears for better hearing warmth during cold weather months!

Turbochargers are operated alongside the new Dual CVVT system, providing 85 degrees of phase compared to the 50-degrees of cam phasing inside the prior Lambda engines. 

Applications of G6DP engine: 

  • 2017 – Present Genesis G70
  • 2016 – 2020 Genesis G80
  • 2015 – Present Genesis G90 
  • 2018 – Present Kis K9 
  • 2017 – Present Kia Stinger 

Engine Tuning, Modifications, and Upgrades

There are four modifications and key changes that Hyundai made for each release. The first engine release is the G6DB engine which has a power production of 235 HP at 6,000 RPM, 226 lb-ft of torque, and a 10.4 compression rating. 

Next up is the G6DF engine with a 270 HP power rating, 235 lb-ft at 4,500 RPM. This engine provides a great balance between power and torque. 

The G6DH and the G6DP are both high-performance engines. The former produces 294 HP, nearly cracking the 300-mark, while the latter breaks the 350 HP barrier at 365 HP. In addition, the G6DP is a turbo engine. 

Problems Surrounding Hyundai 3.3 Lambda Engines: 

As much as we wanted to keep our engine in pristine condition, there are a lot of factors that contribute to the overall deterioration and issue of our engines. The age, mileage, maintenance habits, and other external factors add fuel to the fire to the retiring engine. 

However, you can prevent and stretch the time of the engine depending on your willingness. That is why we put up a brief description of some issues that the Lambda engine might encounter. 

1. High Oil Consumption

Some of the most common problems for 3.3L MPI engines are related to high oil consumption, and this is typical in older cars which also have a lot more miles on them than newer ones would.

Seized piston rings can cause the problem, so it’s important that you change your engine oil at least once per month or as often according to regular maintenance schedules (check yours).

Fresh, high-quality motor oils prolong car life. So, better be ready to use high-quality engine oil. Along with that, a good engine oil extends the life of cam followers and increases intervals between valve clearance adjustments. 

The average useful life of Hyundai Lambda 3.3 MPi engine ranges from 150,000 to 200,000 miles. 

2. Carbon Build-up

Direct-injection engines have problems regarding their fuel delivery system because carbon builds up, especially on the intake valves. This makes the issue, as mentioned above, more pronounced due to the choking tendencies of carbon build-up.

That happens because the engine will exert more effort in circulating the oil to keep the engine running by not overheating. 


Hyundai has created a fantastic engine with their 3.3 Lambda Engines, and it is an excellent addition to the lineup of engines they offer to the consumers. The newest release provides increased fuel efficiency without any decrease in power output or performance due to technological advancements made during production cycles. 

If you’re looking for an engine with excellent power and fuel economy, this engine fits your needs while providing great gas mileage.
