MP4.2+6.0

Doesn't take a rocket scientist to figure out same motor would be headed for D5 too.

Just change Bentagya to D5 A8. Presto. Marketing guys too busy with the superlative Word assist these days to learn the copy and paste function I guess. :/

From today's press bulletin...

The new A8 starts out in the German market with two extensively reengineered V6 turbo
engines: a 3.0 TDI and a 3.0 TFSI. The diesel develops 210 kW (286 hp), and the gasoline
version 250 kW (340 hp).

Two eight-cylinder versions – a 4.0 TDI with 320 kW (435 hp) and a 4.0 TFSI with 338 kW (460 hp) – will follow slightly later. The exclusive top engine version is the
W12 with a displacement of 6.0 liters. (These vehicles are not yet on sale. They do not yet have type approval and are therefore not subject to Directive 1999/94/EC.)

All five engines operate in conjunction with a belt alternator starter (BAS), which is the nerve center of the 48-volt electrical system. This mild hybrid technology (MHEV, mild hybrid electric vehicle) enables the car to coast with the engine switched off, and to restart smoothly. It also has an extended start/stop function and an energy recovery output of up to 12 kW. The combined effect of these measures is to bring down the fuel consumption of the already efficient engines even further – by as much as 0.7 liters (0.2 US gal) per 100 kilometers (62.1 mi) in real driving conditions.

The A8 L e-tron quattro with its powerful plug-in hybrid drive will follow at a later date (This
vehicle is not yet on sale. It does not yet have type approval and is therefore not subject to
Directive 1999/94/EC.): Its 3.0 TFSI and the powerful electric motor achieve 330 kW (449 hp) of system power and 700 Nm (516.3 lb-ft) of system torque. The lithium-ion battery stores enough power for about 50 kilometers (31.1 mi) of electric driving. It can optionally be charged by Audi Wireless Charging. A pad in the garage floor transfers the power inductively to a receiver coil in the automobile with a power output of 3.6 kW.

So, PEH specs are basically the Bentagya and Cayenne. Not very ground breaking. Charger is nice, but come on who is going to install that in their garage floor, let alone work, let alone... And is it compliant to a standard, or another press release orphan?

Basic response on new techno stuff which I let go before: The alternator thing seems like just a 48V amped up version of what is already in D4. That green display with the battery you see on the bar graph fuel economy read out. And I laughed when I got to the punch line of the fuel "savings." What, thousands of $$ of hardware and lots of potential potential for future pricy repair issues, and they got "as much as" 0.2 gallons per 62.1 miles. Lets do the math: that is an incremental, oh never mind it's rounding error. Did they get the decimal pace wrong or something?? Had some engineer brought that to me and then the data, I would have sent him her to the trunk and TDI design Gulag in short order. Engineering money down green toilet. Classic example too of where marketing spin meisters get caught up in the trees and completely miss the forest. Results data sucks in plainest English.

Reminds me of the LS600. And that car is a real hybrid rated at 19 / 23... lol Ridiculous.

S8/S8Plus are already known too.
S8- Panamera V8 4.0 tt with around 540HP (slightly detuned, no idea why)
S8 Plus- Panamera Turbo S Hybrid detuned to about 650HP

MP4.2+6.0

Here is a story on future S8 motors. Big secret from Audi I guess. Not so much in outside world given it took all of two days to get in automotive press.
