In a nutshell:
- Range-topping Alfas get exterior, interior and infotainment facelift for 2020.
- Stelvio now boasts even better acceleration, thanks to the 2.9 V6 BI-TURBO engine producing 510HP, which is in both cars.
- Order books now open, with the Giulia costing from £67,195 and the Stelvio super SUV starting at £73,195 OTR.
- Popular Performance Pages stats analysis remains.
Because the firm has just released details of the updated Quadrifoglio - aka, four-leaf clover - versions of those two cars.
And with increasingly-sophisticated technical and performance levels, Alfa Romeo say the facelifted vehicles simply embody Italian design.
As youre probably aware, Alfas four-leaf clover badge has long adorned its high performance models, in the same way BMW has its M badge, and has signified a road-going cut above since the 1920s.
And the new Quadrifoglio incarnations of the Giulia and Stelvio are as uncompromising, and as tempting, as ever.
The Stelvio super SUV is priced from £73,195 OTR, while prices for the sleek Giulia saloon begin at £67,195 OTR.
Both cars now boast a new 8.8in touchscreen infotainment system, a whole host of advanced driver assistance systems, and there are huge improvements to the look and feel of the cabins.
Both cars still share the same engine as before - a pulse-raising 2.9 V6 BI-TURBO - that produces 510HP and is capable of unleashing 600Nm torque at 2,500rpm.
But one of the headline-grabbing stats is that the Porsche Macan-challenging Stelvio Quadrifoglio is now quicker than its predecessor, thanks to a clever redistribution of torque.
It means the Stelvio sprints from 0-62mph in just 3.8 seconds while the Giulia takes a shade longer at 3.9 seconds.
And there are subtle tweaks to the design of both cars to please the eye - with the Stelvio an outright four-wheeled assassin wearing a sharp suit.
As an Alfa Romeo spokesperson points out: Alfa Romeo's Italian style expresses a simplicity that conceals the complexity of the creative design process. For 2020 the Giulia and Stelvio Quadrifoglio have been updated to create an ergonomic, harmonious series of lines, instruments, volumes and spaces which envelope the driver.
There are new LED rear light clusters with dark lenses on both cars, and a new glossy black finish adorns the front trilobe and rear badges.
The Stelvio also features new 21-inch alloys wheels, seen for the first time on a Quadrifoglio.
Inside both theres more storage space, a new leather steering wheel and gearstick, as well as a host of luxurious and tactile options for the upholstery and seating.
The Giulia and Stelvio Quadrifoglio now feature a 8.8-inch central touchscreen display as standard, and petrolheads will be pleased to learn the Performance Pages - which show everything from real-time acceleration to torque delivery, turbo pressure, power used, and the temperatures of the main mechanical components - remain as in previous versions.
Meanwhile the new raft of driver assist tech is there to bring the thrill of the racetrack and an easier everyday life.
You can flick between two autonomous driving levels. Level 1 only intervenes to ensure total safety and to increase driver comfort in heavy traffic or on longer trips.
While Level 2 autonomy gives the car control of the accelerator, brakes and steering under certain conditions.
Theres also Lane Keep Assist, Active Blind Spot Assist, Active Cruise Control, Traffic Sign Recognition, Intelligent Speed Control, Traffic Jam Assist and Highway Assist, and Driver Attention Assist.
And then theres what happens when you really exercise your right foot.
The Giulia and the Stelvio boast an 8-speed ZF automatic transmission, while the Stelvio is all-wheel-drive and the Giulia is propelled from the rear, and driving modes go all the way up to RACE, where gear changes take place in lightning-fast time.
The Stelvio has a top speed of 176mph, Giulia goes on to 190mph.
Meanwhile the Quadrifoglios should sound as good as they look.
The spokesperson adds: The soundtrack accompanying the Quadrifoglio driving experience is provided by a dual mode quad exhaust system. Customers can opt to fit the MY20 Giulia and Stelvio Quadrifoglio with a new Akrapovi? exhaust, another dual mode system, in titanium with carbon fibre tailpipes, featuring an even more sophisticated sound.
