The new twin scroll 2.0 turbo
#31
p.s. Ouch, you are the first person i see that said that 2.0 turbo from BMW has lag... usually no reviewer ever write that - they say there is no lag at all.. and then when new engine is introduced, they say "unlike old engine that had lag, new one does not" :-).
Unfortunately, I am not in the car industry anymore so I dont get to test cars anymore. Around here even turbo petrols are becoming extinct, especially when it comes to SUVs.
I just checked X3 2.0 turbo efficiency in Germany, and CO2 is pretty high compared to their diesel, despite being updated 2.0l engine (it is not high in reality, but tax system is made to suit tiny cars). i sure hope Lexus can do some magic to the official EU numbers or else taxes will be high enough to make 2.0t not sellable in half of the europe.

Have to second Och and Bit on the Ford v8. I've seen TONS of them with over 300,000 miles and still kicking. Even the old Windsor engines, such as the 351 in our truck is a solid engine that works hard and returns 16 mpg on the freeway doing 75-80 in an old F350.

However, in the case of the M5, a lot of BMW enthusiasts were not happy with the switch from NA V10 to the new 4.4 liter Twin Turbo V8 (S63 engine). One of the disadvantages was that the redline is now lowered.
PLUS, the exhaust sound is downgraded and there is reduced intensity.
Hence, the only remedy is to purchase the optional BMW M Performance AKRAPOVIC exhaust system.
This is not only limited to the M5/M6.
Look at the new BMW M3/M4................they 'downgrade' from NA V8 to this new inline 6 twin turbo......and people were saying "my god, the exhaust is LIFELESS"
Again, it's not necessarily the manufacturer's fault.
But hell, even Formula One is following this trend. The V12, V10 and V8 engines sounded intense (which is what Formula One is about).
Now with these turbo V6 motors, F1 cars sound like lawnmowers.
Again, not necessarily the fault of the manufacturer or the firm.
You can blame governments..........or those motherf***ers that belong to Greenpeace. OR BOTH!!!

A turbo inline 6 MkIV Supra (with aftermarket exhaust, granted) is one of the sickest sounding engines in all of production-car land. Love it way more than any V8. I love it almost as much as I can't F-ing stand these hilariously-overpriced, flatulent, slow-*** Hardley-Ablesons that all these obnoxious wannabe bikers putt around on in AZ.
So I for one welcome the return of Japanese cars to turbos...and bring on the hybrid sports cars as well. Japanese cars are supposed to be about technology, not punched-out displacement. 20 years from now, an NA car will be viewed as a dinosaur.

Toyota, Honda & Nissan's VQ are generally the best V6's around..
For reference sake we used to have a GM vehicle with the 3800 V6 and well it was crap. Extremely unrefined and weak for its 3.8L size.
What was Ford's V6 like in the mid 90s?

The 3.0L 1MZ-FE is very old, I think from 1994. But yes it's extremely smooth and it's no less fuel efficent than other V6's from that time. It has also won a few awards.

Kind of funny that an old 1998 Z28 convertible I had, LS1 V8/6 speed, about 350hp, got 19-20mpg in town and 30mpg on the highway. Provided I kept my foot out of it in town, and cruised at 65mph. Not too far off.
Granted if you drove it like you stole it, and didn't take advantage of its tall gearing, well it wasn't that efficient.

Back to the 2.0 Turbo topic :-)
We got confirmation:
Thats cool then... they just released their 1.3l in new Yaris today, which uses same tech and is part of 14 engines they will release by 2015 with this... they managed to get 30% better fuel consumption on already very efficient engine!
So Turbo should be very efficient as well.
I wonder if this will go to their hybrids in the future as well - ability to switch between otto cycle and atkinson electrically means that possibly they could use otto cycle when you go into sports mode.
This would be quite big - imagine Ct200h/Prius getting extra 32hp in sports mode, it would make them a lot quicker... or even Camry/NX - extra 30hp on flick of the switch. Not sure if they will do it, because then when gunned, hybrids wont get any better efficiency than normal Otto engine... but still, it is possible.

"Through valve timing, when you want performance, you get Otto cycle," Templin said. "When you want efficiency, you get Atkinson cycle."
