Some new, or perhaps not so new, automotive technology...

I know that some of the things that I'm about to mention is not really 'new' technology but I still think that it's interesting and am wondering what others think of this.

First a bit of a back story; we hadn't purchased a new vehicle since 2014 and we hadn't been looking at new cars since we try to buy what we want, take good care of it and then drive it for 10 or 12 years. At the moment I've got six years on my 2013 GMC Terrain and my wife had five years on her 2014 Honda Civic, so we assumed that we would be good for at least another five or six years. Unfortunately, about a month ago my wife was involved in an accident. No one was hurt, but her car sustained enough damage that the insurance company totaled it. For the record, the local police adjudicated the accident as having been 51% to 49% my wife's fault. No tickets were issued, however, they ruled that my wife failed to yield the right-of-way, but that the other driver failed to take any action whatsoever trying to avoid the accident (the police officer's opinion was that while they couldn't prove it, they said the evidence appears to indicate that the other drive may have been distracted, perhaps either texting or doing something else with her cell phone at the time of the accident. She also may have been exceeding the speed limit.). Since the responsibility for the accident was basically a toss-up, our insurance company is NOT going to ding our insurance with a 'chargeable' accident, although we did have to pay the deductible.

Anyway, to make a long story a bit shorter, the payoff from the insurance company was MUCH higher than I had expected, about TWICE what I had estimated when I checked the 'Kelly Blue Book' website (the car was fully paid for so all of the money was ours). This completely changed our plans for what we were going to buy as a replacement. Before we heard what the payout was going to be, we were planning on getting another vehicle in the Honda Civic class (my wife liked the car, just that she wished for something a bit bigger). When we started to look around we decided to go up-scale a bit. Ever since my wife was in high school and a classmate of hers drove a Mercedes, she had wanted one, however we had never considered it, thinking it was just too expensive for our budget. However, we went to our local Mercedes-Benz dealer, sort of on a lark but before we left my wife had a nice 'new' C300 sedan. I said 'new' since it's actually a 2018 pre-owned model that had been used as a loaner car and had only 7,000 miles on it. As a pre-owned, fully certified car, we get the full four-year, unlimited mileage, factory warranty, starting from the date WE bought the car. They discounted the price significantly, particularly when we told them that we were prepared to put a substantial CASH down-payment (we still had to finance the balance but with a credit score of 844, you can get some pretty good deals).

Now this Mercedes C300 didn't have ALL the bells & whistles, but what it does have it still pretty cool. In addition to things that we were already familiar with, like back-up cameras, navigation systems, satellite radio, Bluetooth linking of your cell phone for hands-free use, there were a lot of other stuff that we had never had before. Now some are things that I had experienced in rental cars, like a blind-spot warning system and stop-start engine management, but a few things were completely new for us. This included something called Apple Car-Play where the relevant apps on you iPhone are accessible from the flat-panel display, such as Message and Music. Also a totally keyless entry/exit/drive system, run-flat tires, automatic-folding side-mirrors, memory seats, auto-adjusting seat-belts, Dynamic Select that gives you five different ride/drive response systems that includes settings for maximum economy, comfort, and two levels of sport driving and even a mode where you can customize most of the driving behavior options. It also has a nine-speed transmission with can be driven using F1-style paddle shifters.

What really impressed me is what has been done to improve efficiency. First off, is that this is a four-cylinder, turbo-boosted engine that really responds, even if you're driving in the 'Comfort' mode. I suspect that the nine-speed transmission also helps as it keeps the engine in it's most efficient RPM-range. But there was something that I had not expected. Now this car is NOT a hybrid, but it does have what they call a 'recuperation' system where when you slow down, the drivetrain, using some sort of generative, energy-recovery system that bypasses the alternator and recharges the battery during the slowdown (this is not based on braking as there is a 'charge' indicator on the dash and it lights-up even if all you're doing is backing-off on the throttle and before you apply the brakes). Now this is reported to save gas as the alternator is not engaged full time. This car also has electric-assist steering, which saves robbing engine power (now I have that on my 2013 GMC Terrain but the C300 steering is computer-controlled based on the different driving modes and your speed). We have a neighbor with a 2017 C300 and he's always bragging about the great gas mileage he gets and while I've tended to dismiss his claims, I'm starting to see that perhaps he may be right. Also, they've reduced the weight of the car significantly by replacing a lot of the chassis parts, not the outer body work, but interior structures with more aluminum, as much as 300 lbs or so.

Anyway, so far we've been very impressed by what we've seen and can understand why the C300 has become so popular, at least out here on the Left-Coast.

Oh and one other thing, I've never felt a paint job as smooth as what you feel when you run your hand over the hood or fender of this car, and keep in mind that it is a year old and has been driven 7,000+ miles before we took it home.

Here's a couple of pictures of the car (these are shots of the actual car, taken from the dealer's website on the day we bought it).

I've had a new 1999 C230 Kompressor sedan, a CPO 2004 C240, and now a CPO 2008 E350 4Matic.

They are very nice cars, and (almost always) superbly designed and engineered. The hidden features are as impressive as the explicit features.

Example: typically Reverse gear in Comfort mode is actually a 2nd higher gear ratio. Yes, two Reverse gears. Just in case you need to drive backwards at 50 mph.

Example: in an emergency, trigger the BAS and your face will actually hurt.

When they get older, the cost of repairs can be extraordinary. A simple bushing failed on my '08 E350, but they only supply replacement control arms ($1k) which take most of a day to replace (another $1k). So $2k for a $20 bushing.

I've seen that green regeneration bar graph display on the newer cars (Loaner). If there was any effect then it was imperceptible.


 
Speaking of technology, I just noticed that, while in this new thread, over in the right-hand, 'Related Articles' panel on the Eng-Tips page, there was the following item:


I assume that it popped-up because I had mentioned how Mercedes-Benz was using more aluminum in the structure of the vehicle.

While I'm not advocating that someone should waste their time or the space in a Eng-Tips thread, but it would interesting to see what sort of adverts one could force the system to regurgitate based on the sprinkling of totally superfluous key-words in an ostensibly normal post ;-)

Apologies in advance, this is a joke...

First thing each morning, I spend a few minutes shopping for skimpy bikinis. The rest of the day, the advertising is quite lovely.
 
Not so new technology, but it came to mind:

We loved our 2013 Navigator (short wheelbase), bought when it was a year old, with ~30k miles on it.
... all in hard service; it had served as a rental car, mostly in Atlanta.

It gave relatively little trouble, until this year, when the front (drive) axle started making expensive noises.

I had always been jealous of the long wheelbase SUVs for their extra interior room, and when we happened upon a 2018 GMC Yukon XL SLT (long wheelbase) with 20k miles, we grabbed it. Yeah, it had been a rental car too; the rear carpets are kind of glazed, presumably from salesmen sliding heavy travel cases in and out, but has no other problems so far.

I mostly miss the keyboard on the Navigator's door, which allows you to leave the vehicle locked and running, for the comfort of our dog. No such thing on the Yukon, but it has other nice features.

... The nicest of which is that the engine disables four cylinders when under light load.
On a recent trip from Stratford, CT to our new hometown of Corinth, NY, a couple of hundred miles, the Yukon reported an average above 18mpg. Actually, it was running above 22mpg until the last six miles, which goes over a mountain.

The Navigator had achieved 17mpg once, when I think I got a load of ethanol-free gasoline, but otherwise averaged around 12mpg highway.

Yes, I remember the Cadillac 8-6-4 and its reliability problems.
I'm hoping GM has finally got a handle on cylinder deactivation.

If your GMC has a remote key-fob, there should be a remote start option (the circular arrow as seen below).

If you have this option, and you want to leave the Yukon running with the dog locked inside, just get out of the vehicle, close the doors, press the 'lock' button on the key-fob twice and then press the remote start button until the engine starts. On really hot days, I use this feature all the time with my 2013 GMC Terrain (my wife's 'new' C300 doesn't appear to have this option).

Ford has the Ecoboost engines decently figured out. We recently rented a Expedition Max for a trip to Pittsburgh. It was averaging 23-24mpg through PA on I79. Not bad for a big brick with 5 people and luggage in it. Apple Carplay is handy for bringing up a navigation program. A phone works way better for navigation than any GPS unit I've ever used.
 
Fully agree about using a smartphone for vehicle navigation.

When travelling, most apps allow one to download in advance (at home, over wifi) the map data for the region you plan to visit. It thus requires essentially very little potentially-roaming mobile data.

The phone's integration with up-to-the-minute Traffic data can be better. On a recent trip, my phone kept directing me to switch between the 'Collector' and 'Express' lanes (infamous Toronto 401). The particular rental vehicle GPS gave no such advice. The phone kept weaving me around the various traffic jams.

They're hands-free, because after entering the destination, just drop it into the center console cup-holder (still picks-up GPS easily) and it speaks the directions. No need to touch it.

I like the concept of the vehicle integrating with the phone, instead of the other way around. Problem is that vehicles last much longer than the 3-year technology standards life-cycle.

 
Just joining the love-fest for Mercedes!

I have no business owing one or driving one. That said, I'm 6'-5" tall and actually fit okay in the E class.

Back in '04 when my Park Avenue died, I went to CarMax and saw/sat in my first E-class. It was a wagon and I was sold. Just didn't like the one I test drove. So, we (wife and I) went to the dealer. Sat in and drove an '01 with 85,000 miles on it. It was priced at $22,000 and we bought it. Wow! A Mercedes wagon! But, high mileage, eh?

Drove that car through the better half of 2018, lent it to my son and it was crashed with 330,000 miles. Neighbor now owns it, fixed it and it's on the road still!

Last year after the wreck of the old '01, I then bought a '14 E350 sedan. Just about the last year of the naturally-aspirated 6-cyl. That was a great buy with 30,000 miles and $25,000 from the dealer. Now I got the Bluetooth and iPod connectors! Still haven't figured out the navi, nor most of the other stuff.

Love the car though! And, it gets great mileage! I'm averaging 26-1/2 mpg in combined driving and get over 30 on the open road. Just love my new car!

I never drive the 401 when the 407 ETR is virtually traffic free and they never bill us Americans.

Thanks JRB.
We've tried something similar, but must have gotten the details wrong; the engine stopped when we walked out of range.

They DO charge the Americans. I once drove on 407ETR. They sent me bill and request to open an account, and to do it I had to pay extra, almost as much as for the miles.
 
A phone works real well for navigation near a city in the south, but get into the country up north (less GPS coverage) and the updates take forever. I'll stick with my Garmin.
You want to see features go test drive a new Lexus.
I have an old Toyota Avalon (mostly Lexus parts) and love it.
Big car, near perfect reliability, 26mpg over all with 28-30 on the highway.
I would replace it with a new Hybrid Avalon in heartbeat.

Sounds like there's a market for a car interior temperature monitor and the corresponding app to warn you if the temperature isn't behaving. I'll expect a royalty for that idea ;-)

My phone is a little dyslectic.
I have been traveling recently and within the last two days it twice told me left when it meant right.
The third time I was familiar with the area and disregarded the instruction to turn right and headed for the left turn lane. The phone recognized its mistake and made a correction but it was too late for me to have crossed two lanes of traffic to get in the left lane.
That said, I use it but I don't trust it. I try to check my turns ahead of time so I am not misled by my phone's dyslexia.
Now that I know, it's only mildly annoying.

You didn't mention Adaptive Cruise Control (ACC).

Got this on my new Golf and it works a treat. Basically set your max speed and min distance from the car in front then just steer. It slows down, brakes, accelerates or cruises based on the car in front.

Still doesn't see beyond the car I front (grill mounted radar) so sometime you need to brake earlier if you can see the traffic ahead backing up, but really nice on those busy, but moving motorways when speeds go up and down by 10-15 mph. I love it.

Remember - More details = better answers
Also: If you get a response it's polite to respond to it.
