The Alfa Romeo Brera coupé and Alfa Spider convertible are now available with a new 170 bhp 2.0 JTDM diesel engine, which emits just 142 g/km CO2, equivalent to 52.3mpg.
The end result is two good-looking cars with Alfa badges that are also amongst the lowest emission cars in class. As well as increasing fuel efficiency and lowering CO2 emissions, the new diesel unit also has more power and torque.
The 2.0 JTDM powerplant develops 170 bhp at 4,000 rpm, and the latest incarnation of its MultiJet technology means that the unit delivers its maximum torque of 360 Nm between just 1750 rpm and 2500 rpm.
The new 2.0 JTDM powered Brera and Spider cover the 0-62 mph sprint in 8.8 and 9.0 seconds respectively, with a top speed of 135 mph.
Routine maintenance intervals for the 2.0 JTDM are set at 21,000 miles.
The cars are also available with a new 200 bhp 1750 TBi turbo petrol engine, also with much lower CO2 emissions, down to 189 g/km for the Alfa Brera and 192 g/km for the Alfa Spider.
Thanks to a process known as ‘scavenging’, the maximum torque of Alfa Romeo’s new petrol engine is achieved at just 1400 rpm – little more than tickover speed – with maximum power developed between 4750 and 5500 rpm.
From a standstill, the 1750 TBi engined Alfa Brera and Alfa Spider reach the 0 – 62 mph acceleration benchmark in times of 7.7 and 7.8 seconds respectively, going on to 146 mph.
Routine maintenance intervals for the 1750 TBi version are also set at every 21,000 miles.
