Three advanced new engines with some of the lowest emissions in their segment

The new range is one of the first to offer a complete engine line-up that will comply with the forthcoming Euro 5 emissions regulations which aren't due to be introduced until September 2009. Thee exceptional environmental credentials hasn't been achieved at the cost of driving enjoyment, however, and greater frugality is matched by greater performance and flexibility.

Making its debut is Honda's second-generation diesel engine which builds on the outstanding qualities of the award-winning i-CTDi unit to raise the bar in the diesel stakes once again. Its advanced technology and overall capabilities place it firmly at the forefront of diesel development and underpins the Accord's claim to offer one of the strongest combinations of dynamic performance and environmental responsibility in the marketplace.

Like its predecessor, the new i-DTEC engine is compact, lightweight, refined and quiet in operation. It employs the latest piezoelectric multi-stage fuel injection technology, more efficient exhaust gas recirculation and a particulate filter for significantly reduced emissions. At the same time both power and torque levels have been increased for a sportier driving experience.

Output is 10 PS greater at 150 PS/110 kW at the same 4,000 rpm, while peak torque is now 350 Nm at 2,000 rpm. Improved engine flexibility is reflected in a 9.6 second 0-100 km/h time, yet combined fuel consumption, is only 5.6 l/100km. Equally, CO2 emissions are just 148 g/km.

The 2.0-litre i-VTEC offers similar levels of performance to its predecessor - 156 PS at 6,300 rpm - but builds on its class leading fuel economy. Combined cycle consumption is now 7.2 l/100 km compared to the 7.7 l/100 km of the previous Accord saloon.

Key technological changes include increased diameter intake valves, further optimised valve lift and timing and increased inlet and exhaust air flow volumes.

The 2.4-litre engine is more powerful, delivering 201 PS at 7,000 rpm and peak torque of 234 Nm at 4,500 rpm - up from 190 PS and 223 Nm. Its effortless performance is all the more remarkable given the improved fuel economy - now 8.8 l/100km.

Behind the figures are a compression ratio increased from 10.5 to 11.0:1, larger diameter valves, revised valve timing, and reduced exhaust system pressures.
