BMW 530d
I love turbo diesels, so I rented a BMW diesel in Munich for two weeks over Christmas. I have some observations that diesel readers might find interesting. I wanted to rent an x7 diesel for comparison to my 2021 Tahoe LT diesel, but Sixt didn’t have any available. I wanted to try out the BMW in line six 3.0 liter diesel to compare it to the LM2. The 530d has the 3.0 liter diesel engine and it was available. There are two versions, one has a bigger turbo, the 540d. The x7 diesel uses the higher output diesel. The 530d has exactly the same output hp and torque stats as the LM2, same displacement and in line configuration.
I noticed that the 530d has very strong noise suppression. You have to listen carefully to hear the diesel sounds. It’s more quiet than the LM2. Coming back to the Tahoe after two weeks of 530d makes the LM2 sound more diesel like (fine by me).
The BMW engine has an ever so slight turbo lag not present in the LM2. While the gearing for the 530d is set up for Autobahn speeds, I was able to notice some turbo lag even in “sport mode”, just a little bit that is not present in the GM engine.
BMW electronics and tech. I sat for an hour reading the owner’s manual, but it did not help much. The lay out of the controls, the lack of consistency in design - screen or i-drive, “where’s that button again”? - and the complexity of simple functions presented too steep a learning curve. Nobody wants complicated. BMW designers need to buy a Tahoe. Both cars have the same electronic and tech features. GM deserves high praise for the layout of the stack and the simplicity of the controls. BMW's tech/electronics would be a deal breaker for a lot of people.
Another thing was build quality. The BMW is a unibody, so it’s obviously not going match the Tahoe’s body on frame solid bigness. Overall build quality was very good, but maybe just a bit behind the Tahoe.
Yes, I am comparing apples to oranges. The BMW chassis is super. Its cornering and brakes are mind blowing. It settles in at 120mph+ for fast intercity transit and it goes around curves like it’s on rails. The Tahoe does none of these things. Even so, I'll take the Tahoe any time anywhere.
