The new diesel engines and turbochargers that power a range of vehicles in the range of £30,000 to £40,000 are expected to hit the market next year, with the latest diesel cars in the UK expected to come with the engines as standard, according to engine supplier Daimler.
The engine is an extension of the Daimlers D3 and D4 diesel engines, which the company has been working on since the 2020s.
Daimling says the new engine offers the highest torque at low rpm, and can push out up to 8.5 PSG (pounds per square metre) of torque.
The D3 engine, which has been in service with the D8 and D9, can get up to 590 PSG at 7,000rpm, and the D4 engine, with its 1,600hp, can reach 690 PSGs at 8,000-9,000 rpm.
Both engines will come with an 18-inch stainless steel exhaust system, which will help reduce emissions, while Daimle says it has developed an engine management software that will help drivers identify when an engine is running low on power and how to boost it up.
The company says the D3, D4 and D7 engines are now available in 20-inch and 24-inch sizes, with more models expected to be launched later in the year.
The Daimles new diesel engine is fitted with an upgraded version of its D3 Turbocharger, which makes use of a turbocharger that generates more power.
It can also be fitted with a new dual overhead camshaft with more power, a revised combustion chamber and a larger turbochargant, Daimller said.
Daimler’s D3 diesel engine also has a wider intake, and it has been redesigned to be more efficient and quieter, and more fuel-efficient.
The company said that it has increased the fuel efficiency of the diesel engine by 30 per cent, and is also making significant improvements to the powertrain.
It said it will continue to offer the D6 engine, as well as the D7, D8, D9 and D10 diesel engines in the market, and that it is also planning to offer diesel versions of the new D3 in the US.
The new diesel will come in six models, including a new D4 model, with a maximum output of 7,200PSG, as it does in the new model year.
The diesel will also have a bigger powertrain, with an output of 6,600PSG.
This new diesel is the second diesel engine to come to market this year, after the D1, which was unveiled last month.
The diesel was designed to be the cheapest option for customers looking for a new diesel model, although some have criticised the price, saying it was a bit expensive for the amount of fuel and the weight of the vehicle.
While Daimellers new diesel was not expected to start shipping to customers until 2021, it was expected to reach dealerships in the next few months.
