A new 158bhp 1.6-litre twin-turbo diesel has been revealed by Renault and could make its way to the Megane range soon

Renault has unveiled a new 158bhp 1.6-litre twin-turbo diesel engine. The engine is the first 1.6-litre diesel motor of its kind to be twin-turbocharged, which helps match performance levels of large 2.0-litre engines.

The results are 158bhp at 4,000rpm and 380Nm of torque at 1,750rpm. On top of this, Renault also claims fuel consumption and CO2 emissions savings of 25 per cent, compared to its 2.0 dCi unit. Economy figures are over 70mpg, with emissions creeping under 100g/km CO2.

The first time we’ll see the new engine here in the UK will be in the Traffic van. Although Renault couldn’t confirm at this stage, it’s also likely to feature in the Megane range sometime in the near future. In Europe, the engine will be available in Renault’s replacement for the Espace – due this year – as well as featuring in the Laguna which is due in 2015.

According to Renault, the performance and economy figures have been made possible by exploiting the firm’s F1 technology. The twin-turbo system, for instance, works sequentially to deliver low-end torque through to high power at faster engine speeds.

Elsewhere, cooling and friction reduction techniques have also been inspired by F1 tech. A transverse water flow system cools the combustion chamber, and flexible piston rings adapt to temperature and pressure to reduce friction and maintain efficiency.

Nice engine. I thought someone would of copied Bmw with a smaller engine good idea. Bmw have been doing this for 10 years.

Quote: "Economy figures are over 70mpg, with emissions creeping under 100g/km CO2."

So we have economy figures for an engine? How? In what? Surely economy figures belong to a vehicle with specific weight and drag characteristics? Does this engine move around on its own?

I thought all BMW small capacity diesels are single turbo charged? I don't ever remember a BMW 4 cylinder twin turbo diesel. They twin turbo charge the 6 cylinder diesels just like Jag, Audi, Merc and a host of other manufacturers.

God bless BMW, eh! All manufacturers have had large and small engines, not just BMW! LOL.

Interesting if the TwinTurbo makes it's way in to the Nissan Qashqai.. it's currently a Renualt 1.6dci

123d and 323d both had 4-cyl engines with sequential twin-turbo. 201bhp from 2 litres.

and after 100km those two turbos will need replacement... like in each renault turbodiessel

I mean 100kkm.....
