2024 BMW X5 - 3L Inline 6 + Mild Hybrid (Grand Cherokee will have same powertrain in 2025)

Very impressive powertrain. 3L Inline 6 + mild-hybrid that captures breaking. Not a plug in a hybrid, a mild-hybrid that just stores regenerative energy. 0-60 in sub 5s

Grand Cherokee will eventually get this same transmission, when WL74 (five passenger) and WL75 (seven passenger) get their refresh in Calendar 2025 / Model Year 2026.

Several automakers —VW, BMW, Jaguar Land Rover, FCA, to name a few— went with a similar formula: a 2.0 inline four that could be expanded to a 3.0 inline six and, eventually, to a 4.0 inline eight.

Most automakers stopped with the 3.0 inline six and increased power through the use of turbos.

What I find more interesting is that BMW’s 2.0T used on Minis and some entry level BMWs barely makes 190 HP on premium gasoline. Meanwhile, FCA’s similarly sized 2.0T makes almost 100 HP more on Jeep Wrangler and Alfa Romeo Giulia, on regular gas to boot.

And, so far at least, FCA’s 2.0T has proved more reliable and durable than BMW’s.

The entry level 2.0T makes 197 hp on premium in the Giulia, and 200 HP on regular in the Compass. Low boost turbo for fuel economy is a thing. Premium for fuel economy is a thing in Europe, but not in the US as Fiat sadly found out with the Dart and 500/L. Fiat made a massive mistake by not offering a 200 HP version in the Giulia for the US market. If in doubt, see Giulia sales in the US.

Giulia requires premium gasoline for 280 HP, Jeep makes 270 HP on regular.

Mini offers their 2.0T in 189, 228 and 302 HP trim, the latter a number the FCA 2.0T has yet to match in a production car.

None of those automakers ever had plans for an inline 8 out of that modular family. And BMW’s B48 I4 and B58 I6 have been extremely stout, perhaps the most reliable motors of BMW’s modern age. It’s actually been quite remarkable.

From what I have seen, the only problem with the B-series engines is BMW's perpetual problem with cheap gaskets.

Tthe HPFP fiasco was quite remarkable as well.

Irrelevant to cars with the two engines I mentioned. The conversation was about the FCA 2.0t and BMW’s B48 2.0t.
