The 197bhp 1750 TBi petrol and 168bhp 2.0 JTDM turbodiesel were both launched last year in the Alfa Romeo 159. In a more heated form, the 1750 TBi petrol engine has also found its way beneath the bonnet of the Alfa Romeo Giulietta we drove in Italy recently.
In the Brera and Spider the new 16-valve, twin overhead camshaft 1742cc motor is good enough for 0-62mph in 7.7secs for the Brera and 7.8secs for the Spider, while both top out at 146 mph.
The new turbodiesel, meanwhile, develops its maximum torque of 266lb ft between 1750rpm and 2500rpm.
The 0-62mph sprint in the diesel is dealt with in 8.8secs in the Brera and 9.0secs in the Spider. Top speed is 135mph. Of course, the key appeal of the diesel is its tax-friendly status: CO2 emissions are reduced to just 142 g/km
Stat fiends can pore over the finer technical details of the new engines with our shamelessly-stolen-from-Alfa's-press-release tech spec below.
