The…freshly painted version of the 4C sports coupe concept will be joined at Alfa Romeo’s Frankfurt Motor Show stand by the updated variants of the Giulietta and Mito hatchbacks.

The Giulietta gains Alfa Romeo’s new double-clutch TCT transmission that will be offered on the 1.4-liter turbocharged MultiAir gasoline engine and the 2.0-liter turbodiesel, both of which have a maximum output of 170HP.

With the TCT, average fuel consumption and CO2 emissions on the petrol model fall to 5.2 lt/100 km (45.2 mpg US) and 121g/km respectively, and on the diesel to 4.5 lt/100 km (52.3 mpg US) and 119 g/km respectively.

And that’s without sacrificing performance. In fact, the 1.4 MultiAir’s time for the 0-100 km/h (0-62 mph) sprint is 7.7 seconds and its top speed reaches 218 km/h (135.4 mph). Likewise, in the 2.0 JTDM the TCT brings the Giulietta to the top of its class, with a 7.9 seconds time for the 0-100 km/h (0-62 mph) sprint.

Alfa’s smallest model, the 3-door MiTo, will also show something new to visitors of the Frankfurt Motor Show: the new 0.9-liter, turbocharged two-cylinder TwinAir engine that we first saw at the Fiat 500 and which won the coveted “International Engine of the Year 2011” award. The two-cylinder unit develops 85HP and, depending on the DNA program, 110-145Nm of torque.

According to the Italians, its MultiAir technology and the auto Stop-Start system enable the new version of the MiTo to consume up to 30% less fuel than engines with comparable performance and at the same time achieve a best-in-class CO2 emissions figure of just 98 g/km.

In addition, the new MiTo MultiAir will be offered in a new “Nero Ametista” body color along with new-design alloy wheels and a two-tone black dashboard and mesh seat trim.

Last, but not least, the MiTo will soon get a new 1.3-liter JTDM turbodiesel engine with variable turbocharger technology and Start-Stop technology as standard. Like its petrol counterpart, this second generation Multijet engine has an output of 85HP and is Euro5 compliant. It emits 90 g of CO2 per km, its average consumption is only 3.5 lt/100 km (67.2 mpg US) falling to much as 2.9 lt/100 km (81.1 mpg) on the highway.
