New Car Break-in

[WhoIsHomer]

Just curious what everyone has been doing to break in their new G70's? Have you managed to avoid hard acceleration/WOT?

Seems a bit unrealistic to expect that people will never open up a car like this for the first 1000 miles. I suspect that as long as you don't flog the car, don't keep the pedal to the floor for extended periods, and don't pounce on the brakes, it'll be okay with a bit of exercise. I'd actually worry more about warping the brake rotors by stomping on the brake pedal from high speeds than damaging the engine by opening it up for a brief period. Maybe dealers or mechanics with more direct experience can give us a better answer.

I have never been really easy on a car during break in, but I also try not to bag it. No launch control for me yet, and but I don't shy away from full throttle.

Just passed 700km this morning so I am close...

Two schools of thought:

• Do the 1600-2000 km break in
• Drive it like you stole it

I subscribe to the second one. I have a modded car with over 210,000 km and I drive it hard with no engine issues. Drive the car as intended -- it is broken in at the factory.

This is from Chrysler, but I have seen similar advice for other brands:


A long break-in period is not required for the engine and drivetrain (transmission and axle) in your vehicle.
Drive moderately during the first 300 miles (500 km). After the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or 90 km/h) are desirable.
STARTING AND OPERATING
While cruising, brief full-throttle acceleration within the limits of local traffic laws contributes to a good break-in. Wide-open throttle acceleration in low gear can be detri- mental and should be avoided.

I've built a few engines, and the ones I did a hard break-in ended up being the strongest (ie having the best compression and ultimately producing the most power). Even so, new engines have already had the initial break-in completed at the factory, so it shouldn't be an issue, and it really won't make much of a difference whichever way you do it anyway.

so launch control day one is okay?

Yep, not just the engine. There are a variety of bearings and transmission parts that will wear in as you go. Unlike days of old, you don't need a lot of miles, but a couple of hundred does not take long.

I haven't seen the owners manual for a Canadian G70 (or any Canadian Genesis), but the other USA Genesis manuals have a break-in period of 600 miles (which would be 1000 km in CA).

I don't think there are only two schools of thought as listed above, since the USA Genesis owners manual says don't exceed 4000 RPM, but don't drive slow either, and vary your RPM as much as possible. Speed of the car is completely irrelevant, as it is RPM that matters. They recommend keeping RPM between 2000-4000 when possible.

I don't think brakes a big deal. Even if they not broken in properly, they are relatively inexpensive to replace compared to an engine. But I wouldn't do any extremely hard stops during the break-in unless it is required to avoid an accident or something. Of course, I personally wouldn't ever do any extremely hard stops unless I really needed to.

The manual says 1000 km break in where you don't race the engine, go over 4K RPM, or use launch control.

Of course! The transmission will prevent you from launching for a while if it needs to cool down but I have done 5-6 launches in a row with no issues. Just drive the car.

That's pretty much 1). You don't drive it like you stole it if you cap out at 4k RPM.

The break-in period is 1000 km, not 1600-2000 km. I think 4000 is pretty high, since I can go 70 MPH (113 kph) at 2000 RPM. It's not really all that often that I go above 3000 RPM, even after break in. Too much traffic congestion.

Yeah the number I quoted was from my VW/Audi/Porsche days. Either way, 1000 km of trying hard not to push the car or just have fun with the car -- all my cars have been pushed with no issues.

I appreciate all the great discussion. When I actually get my G70, all this helpful info, as well as what will probably be 30 hours of cumulative video review watching will make me an expert.

Genesis should hire some of you to train their US sales people, because you already know 10x more than they will.

HAHA we should all band together and each open our own Genesis dealerships in our respective states that we are all from.... guarantee we know more than the majority of Genesis "dealers" out there!!

Rather than start a new thread, I figured I'd bump this old thread up.

I'm due to take delivery of my 2022 G70 3.3T Sport tomorrow evening. I read somewhere that Genesis recommends a 600 mile break-in period - is this still the case? The guidance I read was keep the RPM under 4,000, vary the speed and throttle pressure, and go easy on the breaks.

TIA for any feedback.

That is about it. Drive somewhat normal, just avoid the full throttle for a while. Keep in mind, it is not just the engine but differential gears and the entire drivetrain.

I read that Corvette is actually programmed for a max of 4000 rpm for the first 500 miles.

Thanks Ed. I've heard similar about the 'vette, but I've also heard many high-end manufacturers "pre-stress" the engine in order to eliminate the need for a break in period.

I need to travel about 300 km on Thursday, so I'll use that trip to start the process.

God, give me strength and wisdom to avoid the temptation of driving my new car to the fullest extent of its capabilities.

Congratulations, and please post photos, as we’d enjoy seeing the new design. I think just for fun I’ll head over to my local dealer just to have a peek at it live, as they have several 2022s in stock, even though I will not be in the market for a new one for quite some time.

My solution to keep myself in check for those first few weeks to drive it in Smart mode and avoid Sport mode. Even now that I’ve had my 270 for almost a year is that so far, the Smart mode rarely takes me out of comfort and has a fair amount of time in Eco mode.

I suppose having a break in gives you more incentive to drive a few more miles to get yourself ready to early drive the car as it should be driven.

Enjoy!
