Thanks Mr Quadzilla (and congratulations on the impending reboot of your long-successful series).
Here's 411 from Volvo. If the use of "supercharging technology" doesn't mean supercharged, then I was loose with the words. My bad. No soup for Steve. It was a pleasant hour behind the wheel but I didn't look beneath the hood — we were off to another event.
"Utilizing both supercharging and turbocharging technology, these direct-injection powertrains have been optimized to deliver higher performance than today's six-cylinder units while offering lower fuel consumption than most four-cylinder engines."
BTW, my pretty colours didn't translate into the online ink. The Volvo was the only Eco-Run car whose actual ratings came within 10% of EnerGuide's. (The other 3 bolded ones — Cadillac ELR, Ford C-MAX Energi, Porsche Panamera S E-hybrid actually beat them!)
Regards,
