Toyota/Lexus Goes Turbo & Improves Infotainment System

That's one thing I do appreciate about Tesla. They listen to their customers and are constantly updating the infotainment software in their cars.
Seems like when you take your Tesla in for service, you don't get an oil change, they give you a software patch and update lol. I've also heard that they have offered software updates on their earlier production cars for free, fixes that take care of problems customers have complained about, like the fiddley door handles that pop out.

MB and BMW seem to be doing quite well with their turbo engines replacing larger and thirstier NA motors. No reason why Toyota should be so far behind.
In terms of infotainment systems, I'm pretty sure Toyota values reliability above all else. Since car play and android auto both reside on top of a QNX base, I'm sure they'll implement both when the time comes.

the benefits aren't really fuel economy, they obviously allow an engine to produce more power by forced induction but modern turbo engines are designed to have a dual personality, so the turbo stays out of things when the car is driven sedately, and gets completely into things when the toe goes down on the gas. so a vehicle can have a smaller engine than it's non-turbo counterpart, so that when driven sedately, the smaller turbo engine will deliver higher fuel economy than the larger non-turbo one. ford is completely on board with this terming it 'ecoboost' implying you get the best of both worlds, power when wanted, and economy when not. it actually works pretty well overall. the trade-offs are that a smaller engine typically doesn't sound as nice, often isn't as smooth as its larger non-turbo counterpart (although huge strides in nvh have been made), and a turbo can generate enormous amounts of heat and stress so an engine must be made more stout to handle that (or risk reliability or longevity).

But this is assuming that at least 50% of normal driving can be done off the boost (i.e. the smaller engine has enough torque for a good amount of city driving). Walking downtown, I can hear the turbos working on the 3 Series and Ford products as the drivers accelerate on a green light. If the turbos are working in those scenarios, there isn't much of a gain in real world city driving, is there not?
Of course on the highway, you will be running on 4 cylinders rather than 6 cylinders so there are gains there even before factoring in transmission gearing.

Bitkahuna thanks for the insight. However if I were a manufacture required to meet some mpg standard then I'd opt for cylinder deactivation while still maintain real mpg. If were basically just playing a numbers game with the feds then let's say an eight cylinder goes to four do the math and submit the est mpg under the four cylinder thus achieving the same goal. Why mess with turbo?

For instance, in NX comparo, all the turbos were supposed to be very similar in fuel consumption, but in reality differences were huge. For instance where XC60 with new turbo was supposed to have best mpg according to EPA, it had the worst and NX had the best - difference in MT tests was 20.9 vs 23.9 MPG - which is as big as it gets for same type of vehicle and almost the same specs.
Of course, when comparing to NA engines, it is also very important that NA engine is state of the art engine... which they usually are not, especially smaller ones... instead they are used for base options so possible advanced features are removed.

evident, thanks for the link, but please post what a link is about in future so people don't have to click to find out what it's about.

$1.30/litre *144 litres = $187.20 tank (Granted, you'll fill up before the light comes on so it won't be a 144 litre fill).
