Petrolicious Pick: Lancia Delta S4 Group B

28 July, 2016

When a new video drops on the Petrolicious YouTube channel, we’re always excited to see what it’s all about. Recently we wrote an article on the Renault 5 Turbo, and asked the question of whether the Renault 5 Turbo was the ultimate ’80s hot hatch? The response from the readers was a loud one: no, nothing would beat the Lancia Delta. For John Campion, who immigrated to America in June 1984 — with only $26 in his back pocket — the Lancia range of vehicles was his choice of vehicle, too. 

After a few “lucky breaks” as he describes them, John was able to become a successful businessman in America. This meant, for his automotive passion, he was able to collect vehicles from his youth, mainly focusing on rally cars. And because the best rally cars that were ever produced were made in the ’80s, this is where his collection began. 

When you look at the specs of the Lancia Delta S4 Group B, they’re nothing short of phenomenal. The road-going Delta S4 weighed in at 1200kg, whereas the Group B version weighed in at a mere 890kg. This alone would aid in serious performance gains, however Lancia also wanted to work their magic on the engine. By pioneering twin-charge technology, Lancia was able to extract massive horsepower and response from their mid-mounted 1.7-litre engine. As turbochargers in the ’80s were nowhere near as sophisticated as they are now, if you wanted big power, it came at the expense of turbocharger lag.

Utilizing a supercharger with a bypass valve, Lancia was able to have almost instantaneous boost pressure at any rpm. Once the turbocharger was on full boost pressure, the bypass valve would cut the supercharger out of the equation. Official horsepower figures of the Group B version were 480hp, while some sources implied it was closer to 560hp. During testing, the Lancia’s engine managed to handle five bar (72psi) of boost pressure, with 1000hp as a result. 

We recommend turning the volume up for this one, so you can best enjoy the Group B sound!

Having dominated the world motorcycle championships of the 1960s, Honda had a crucial decision to make in 1969. Would Soichiro Honda heed his engineer’s pivotal advice?
“Very few examples of the early Civic, a car that set Honda onto the path to becoming a giant of the car world, remain road registered in New Zealand.
Retired Tauranga owner of this example, Graham Inglis is thrilled with his classic little Honda Civic, the first of eleven generations built so far by the company. The Civic became a household name.
“It’s quite amazing the number of people who not only wave, but come up to me in the street and tell me how much they like the little Honda and its colour, and then they want to start talking about it. A guy in our vintage car club wants to buy it and he has been pushing me a bit. It’s not for sale,” he laughs.
Graham bought his 1977 Honda Civic from Wellington enthusiast Julian Foster, who was the instigator of its restoration.”

“Everyone asks that until they take a closer look,” says its owner today, Brent Harris of Auckland. “They also ask if I’ve done the restoration myself, and I have to tell them no, it is 100 per cent original. It’s the paint listed in the handbook.”
It was the original condition of the car that won Brent over from the moment he first saw it — that and the fact “it just looks stunning”.
Brent had owned a 1968 Mark II Cortina for four years. It was in need of some work and the question arose whether to spend the money or get something different. You don’t get much more divergent than Ford’s different approaches to its markets in the UK and the USA.
