Tony MorettiHOST
MG created the Metro 6R4, with a naturally aspirated V6 mounted in the middle of a tiny hatchback body.
Tony MorettiHOST
Lancia developed the Delta S4, perhaps the ultimate expression of Group D excess.
Tony MorettiHOST
It used both a supercharger and a turbocharger.
Tony MorettiHOST
One helped provide immediate response at low engine speed, while the other delivered immense power higher in the rev range.

Ty ElledgeHOST
Several leading teams and drivers withdrew after learning what had happened, arguing that the rally could not continue safely.
Ty ElledgeHOST
But the season continued.

Then in May 1986, the Tour de Corps delivered the tragedy that ended Group B. Henry Toivonen and his co-driver Sergio Cresto were competing in Alonso Delta S4.
Ty ElledgeHOST
Toivonen was one of the sport's brightest talents, a driver capable of astonishing speed and control.
David EvansPANELIST
You know, there was just some presence.
David EvansPANELIST
You still, you look at a Delta S4 today and it still looks like a spaceship.
David EvansPANELIST
You know, they were insane for me.
David EvansPANELIST
But my point which concerned me was when you said that we hadn't had close competition with manufacturers.
Richard MorganGUEST
At the time, the Beetle had a 2.4 liter supercharged engine.
Richard MorganGUEST
I thought, you know what? My favorite car of the Group B rally era was a Lancia Delta S4, which had a supercharger and a turbo on.
Richard MorganGUEST
It did.
Richard MorganGUEST
And I wanted to build a new engine like that.
GinoHOST
So each side had one intake and exhaust, but they were set opposite ends.
JustinHOST
Oh, it's in the Delta S4.
JustinHOST
Yeah,
GinoHOST
and it would shut down one side exhaust at low RPM and just boost off the one turbo and then open the other one up at higher RPM and boost off both because they're insane.
