Volvo is claiming a revolution in diesel engine technology as part of its all-new engine family.
From the autumn, Volvo will roll out its exclusively 2.0-litre, four-cylinder DRIVE-E diesel and petrol engines initially in the S60, V60 and XC60. These will replace eight existing engine families across all model lines and spell the end four five-, six- and eight-cylinder Volvos.
The engines will be offered with different levels of turbocharging and, in some instances, mated to front or rear-mounted hybrid systems for front- or all-wheel drive to power anything from a super-frugal economy model to cars with performance comparable with a V8.
Each will be hooked up to a new eight-speed automatic or “enhanced” six-speed manual gearbox.
The diesel breakthrough, Volvo claims, is with its i-Art injection technology. Each injector in the common rail is fitted with a small computer that ensures the optimum amount of fuel is injected into each cylinder at a pressure of up to 2500 bar, rather than each injector providing a constant, single pressure. Improved economy, performance and sound are all promised.
The first DRIVE-E diesel engine to get the i-Art technology will be the D4 unit with 179bhp. Diesels with between 118bhp and 227bhp will be offered.
The Volvo designed and developed DRIVE-E engine family, which was known as Volvo Engine Architecture or VEA through its development, also includes petrols with between 138bhp and 300bhp-plus.
The first petrols are a 302bhp T6 and a 230bhp T5. Higher performance petrols feature a supercharger as well as a turbocharger to provide more low-end torque for a more linear torque curve and normally aspirated feel.
