New Audi SQ7 with Electric Turbo

[Lexus II]

Audi is working on a new generation of its Q7 and we’re expecting the big SUV to be the first to feature the German automaker’s new diesel engine equipped with an electrically-driven turbocharger. The technology, called e-boost, is designed to eliminate turbo lag at low revs and according to comments from Audi’s R&D boss we’ll see it first in a new SQ7 performance SUV.

A version of the engine shown in an RS 5 TDI concept car produces an impressive 385 horsepower and 553 pound-feet of torque, the latter generated at just 1,250 rpm. In the RS 5, this enables 0-60 mph acceleration in just 4.0 seconds and a top speed of 174 mph. These figures are comparable with those of the stock RS 5 and its gasoline V-8 but with the high-tech diesel the stated fuel economy for the European combined cycle is an incredible 44.4 mpg.

The SQ7 is the first use of this technology in a production vehicle.  Expect many more companies to follow.  Porsche, BMW, and Mercedes will most likely be the next. German engineering at it's finest!

The porsche 918 and mclaren p1 have good hybrid systems but first time I heard of electric turbo. Tough choice which one I will buy to replace my 2004 civic

There has been thought about making the water pump, oil pump, radiator fan,  electric as well.

I know the radiator fan is already electric but think how much better it would be if the water pump continued to run for a minute after you kill the engine.

Think how much better it would be if the oil pump started and brought the oil up to pressure when you insert the key, but before you actually turn the engine over.

To accommodate all this they are thinking of raising the voltage of the electrical system from 12 volts to 48.

This is the automotive technology breakthrough of the year!

Ten years from now this system will probably be used on most engines!  BMW already has a patent for a similar system.

It works by having two turbos.  The primary turbo is powered by exhaust.  The secondary turbo is powered by a 9 hp electric motor which spins to 70,000 rpm in 350 ms and only fires when the primary turbo is waiting to spool up.  Thus eliminating turbo lag and allowing a larger primary turbo.

The RS 5 TDI Concept has a dedicated 48-volt power system providing the large quantities of energy needed to feed the electric turbo.

Bottom line, more power from less fuel.

Gay.

I'll take my regular old internal combustion engine anyday, nothing else has the same overall experience of sound/acceleration/feel of rowing through the gears with a naturally aspirated 800hp 8000rpm 500 cubic inch big block chevy.

This coming from a guy that rolls a Mercedes-Benzo. Audi , joke car for wannabes. VW car with fancy halogen headlights.

electrically-driven turbocharger.

WHY THE FUCK DIDN'T I THINK OF THAT?

Instant torque, no lag!!!!!!!!!!!!!!!!!!!!!!!!

Meh.

[Roger Bacon]

Meh.

I don't like it either, but it sounds like a good idea.

Go with your first instinct.  It's a great idea!

Without this type of technology, gas prices would be so high you couldn't afford to enjoy a 500 cubic inch big block running at 8000 rpm.

The RS5 gets 44 mpg and can accelerate from 0-60 in 4 seconds.  Think about how crazy those numbers are together.

A 9 HP electric motor that runs on 48 volts will draw 302 amps.

Meh. Bro, my standards are so far off into space that 0-60 in 4 does not impress me in the least.

I work in the racing industry.

For comparison, I just got back from where our companies (well, my old company as I literally just switched, but I was still involved today) sponsored car was running 0-308mph in 4.1 seconds.

(Don't get me wrong, I understand their place, I do, I just don't really care/am not impressed.)

Theres all kinds of amazing, crazy off the wall ideas that they're trying right now to get power and mileage... once they start to become mainstream and I start seeing them regularly in the industry I'll start taking notice.

302 amps? Holy shit....

302 amps? Holy shit....

Well short of the 1.21 Gigawatts needed to be sent back in time though.

Another common car has been the TT Vettes knocking down 25mpg on low boost and making 1500hp when turned up. Those things are crazy. A lot of guys have been road racing those cars
