Let’s talk R ECU
Using an R ECU in a Turbo
What happens when you use an 850 R ECU in a regular 850 Turbo?
Bonus! More on the Volvo 850R
Volvo has only sold road cars under the Polestar brand name for a few years now, but back in 1996 it offered something very similar, the 850 R. The original 850 R wasn’t a hardcore performance car out for BMW M5 blood, but like today’s V60 Polestar, it mated Volvo’s sensible qualities with some decent real-world performance.
The 850 R was powered by a turbocharged 2.3-liter five-cylinder making 240 hp, and mated to a four-speed automatic. Based on MotorWeek’s testing, this combination delivered a 7.3-second 0-60 mph run, though the 850 R’s braking performance was even more impressive. It took just 100 feet to bring the 850 R from 60 mph to a halt–impressive even by 2017’s standards.
MotorWeek’s John Davis praises the 850 R’s handling and straight-line performance, but criticizes its harsh, not-very-luxurious ride. You could say many of the same things about the current V60 Polestar.
