Would you purchase a vehicle with a GDI engine?

[GRIFF]

Once having investigated the operation of a GDI engine and it's tendency to leave behind carbon deposits on the intake valves, I am re-thinking a decision to purchase any vehicle with GDI due to longevity issues.

I am interested in any other opinions?

Also, has anyone with a Hyundai GDI engine had any issues relayed to this?

My friends who own Corvette (GM) and Mitsibishi engines have had reduced performance issues requiring the heads to be pulled and cleaned up at around 40,0000 miles.

I love my 2012 Genni 5.0 but may go Honda rather than a Santa Fe due to engine concerns.

It seems Hyundai has made the BIG bet on GDI engines. The industry is just now about to see how GDI holds up after 100,000 miles. Most GDI engine developement was torture tested on sustained highway speeds. The weak link in GDI is stop and go . The risk is in buying used GDI vehilcels out of warranty.
Hyundai just launched the new 200,000 mile 20 yr warranty. It's interesting that they also just started the 3.8 V6 crate motor program. Go figure and add the 2 together. I would buy a New Hyundai GDI with 20 yr 200,000 drive train warranty and keep the stop and go to a minimum.

Yes, I just did.

I believe the one year old C7 is the only Corvette to ever have a DI power plant.

And the new Silverado has a GDI engine. GM spent hundreds of millions of dollars retooling for a GDI engine.

GDI is the future - it's the only currently feasible way to achieve the practical requirements of hp/torque and the mandates of smaller, lighter and more fuel efficient engines.

My understanding is that all new Corvettes now are provided with GDI wngines, the Ford Eco-boost is GDI a GDI engine, the Mazda sky active technology is GDI, all GNC trucks use DI and most, if not all of Hyunadai's are now provided with GDI engines.

Mercedes and BMW used hem for years in the past with a bunch of problems.

Toyota uses a modified version of GDI where they inject some of the fuel upstream as well as DI but they keep the valves clean and Honda uses no DI engines as of yet.

BMW's N55 I-6 Turbocharged engine (5-Series) is DI, as is the current twin turbo V8 in both the 550i, X5, 7-Series cars. All the new I-4 engines they are using are DI engines. I have lost track of MB's engines these days, but BMW is definitely in the GDI game.
