Typical gen cycle for toyota (mostly main bof vehicles)

here is a gee whiz info

toyota typical gen cycle (the dates listed are model years (MY) not production years (which usually start in august of the previous year)

1. 3-4 year is considered mid cycle refresh
2. normally gens last 7 MY (model years)

that all went out the window in the mid 2010's on the bof vehicles.

tundra went like 14 yrs between gens:

1G xk30/xk40 (internal model code)
2000-2006

2G xk50
2007-2021
2014 was consider the mid cycle refresh

3G xk70 (dont know why they skipped xk60)
2022-present


4runner went 15 yrs between gens

predecessor (toyota trekker)
n30
1981-1983

1G n60 (internal model code)
1984-1989

2G n120/n130
1990-1995

3G n180
1996-2002

4G n210
2003-2009

5G n280
2010-2024
mid cycle was 2014 (since they were expecting to switch to a new gen in 2018 but was put on hold)

6G n410
2025-???


tacoma

1G n140/n150/n160/n170/n190 (internal model code)
1995-2004

2G n220/n240/n250/n260/n270
2005-2015

3G n300
2016-2023

4G n400
2024-???

 

Moving forward, I think it's important to consider for the first time, EV laws will probably have a role in the gap between generations.

California's zero-emission rules will cut smog-causing pollution from light-duty vehicles by 25% by 2037.

The rules mandate 35% of the new cars sold be plug-in hybrid electric (PHEV), EVs or hydrogen fuel cell by 2026.

That proportion will rise to 68% by 2030 and 100% by 2035.

12 other states have adopted same rules CA created. UK has some updates to their EV regs as well.

But still being fought over at political level.

If all these laws come to fruition, it would make sense current gen would probably last 10 years and 7th gen would be EV.

 

There's a blurb here I think is on-topic and folks will find interesting:

Also less related but a quote from the comment section I agree with.

 

Yep, basically they designed a one-size fits all platform, which means they had to engineer it for the largest/heaviest it would be used for, then fit all other vehicles (in the same class) to fit.

Saves massive amounts of design time, engineering, parts manufacturing, cataloging, etc. between all the new vehicles. Very smart.

 

Weird. They did the same thing with the Celica/Supra and Supra. The 2nd gen was the MA50, and the third gen was MA70, or JZA70 in some markets. I could assume it gad something to do with the Celica sharing a platform and then getting a new FWD chassis code, but that doesn't explain about the Tundra.

Edit: it looks like the Celica got the RA60 chassis code, while the same generation Supra was the MA50. So, that really doesn't help explain anything. I just thought it was interesting.

 

Supra MK2 was MA60, MA61, (81~86) and MA67 which was revisions on the MA61.

 

Crap, I stand corrected. Not sure why I thought it was the 50.

For being a fan since before they were really popular (pre Fast and Furious, lol), I'm surprised I didn't know that. Especially since the VIN code on mine was MA67. Duh.

Thanks for the clarification!

 

Np. The old numbers can be very confusing sometimes.

 

I don't think they're that confusing. I just had it wrong for whatever reason. I tried to remember chassis codes for all of the cars I liked. I still know a handful, but now I'm going to need to double check before I post them.
