D5244T16 - is it a twin turbo?
Hi all,
Since few days I am happy to own a XC60 I bought the car second hand (it is approax 1.5 years old) and I've received some controversial info so far regarding the engine. My XC60 (MY2010) is equiped with the D3 engine which is the same as D5 - 2.4 liters but with less power (different software and injectors). The engine number starts with D5244T16. My dealer said that the engine sports a single turbine, while searching for this particular engine in the net I found info that D5244T16 is a twin turbo engine. These are the engine specs from RICA: 2.4D Euro 5 (163 hp / 420 Nm) - Available MY 2010 onwards - VIN Code YV1xx80 - D5244T16 - Twin turbo engine - Tunes to 245 hp / 500 Nm - Found in XC70, XC60 - Same engine as the D5 Euro 5 205 hp - Only available for the certain markets source: http://www.rica.nl/identify.aspx other info re the engine could be found at: http://en.wikipedia.org/wiki/Volvo_D5_engine What is confusing (at least to me) is that Volvo are labeling as D3 their 2.0 and 2.4 engines. The pull is quite good so I don't feel a substantial 'turbo hole'. Could it be that the dealer is wrong? |

Open the bonnet and have a look.
Twin stage is slightly different. One small turbo for low driving speed and when you boot it, boost bypasses the little one in favour of the big one. Best explanation I could find on the net. With Twin Stage Turbo we have a small turbocharger operating at low rpm for optimal low-end-torque and response from low vehicle speed. This small turbo is passed when the required power output increases and a second turbocharger with higher size comes into operation. Besides the improvement of overall performances, the TST technology allows increasing the EGR rate without penalties on fuel consumption and therefore gives a relevant contribution towards NOx emission reduction.

If it's a t16 it is a third generation twin turbo.....have a look at wikipedia ....search for volvo d5 engine.......it lists all the variants and specs for all three generations of the five cylinder diesel

Thanks Blue693,
T16 is indeed the twin turbo version of D5, I've got it confirmed from other sources as well. Interestingly my dealer didn't knew that. They dont have to know all the details...but hey this is quite an important one! |

Is this a twin turbo?
It seems the XC70 in France was sold with a 2.4l D3 badged engine for a short time between 2010-2011 as D3.
The engine code is D5244T16 Is it possible to see from this image if the engine is a dual turbo or not? Last edited by sacke; Jul 1st, 2024 at 11:38. |

The small turbo is hiding under the metal guard behind injectors 2 and 3 with the big turbo down the back of the engine.

Yes, it's mechanically identical to a (twin turbo) D5, just de-mapped to 163bhp.
cheers James
