 Alfa legends return

When it comes to car fans it is hard to top the ‘Alfisti’ for sheer brand loyalty and fervour – and they all should be ‘shivering with antici. . . . . . .pation’ right now, awaiting the arrival of a few of the extremely limited production Alfa Romeo Giulia GTA and GTAm headed to South African shores. 

Just 500 numbered cars are being built by Alfa Romeo and South Africa’s proud Alfa Romeo legacy and competition association with the nameplate has secured a very limited allocation. The order book is officially open and fortunate owners will not only acquire a legendary performance car, but an equally tasty experience and package of accessories with it. 

The acronym GTA stands for ‘Gran Turismo Alleggerita’ (alleggerita being the Italian term for ‘lightened’), and it originated in 1965 with the Giulia Sprint GTA, a very special model based on the Giulia Sprint GT, designed as a sports car and presented at the Amsterdam Motor Show staged that same year. 

The body of the Giulia Sprint GT was replaced with an identical version in aluminium, for a total weight of 745 kg compared to the 950 kg of the road version. A second, but significant variation concerned the 1570 cc twin cam engine which, in standard road configuration, with dual ignition, reached an impressive output of 86 kW.

 


The technicians at Autodelta, the official Alfa Romeo racing team, chose it as the reference vehicle for the Touring category and developed it to achieve a maximum output of 127 kW. The model’s competition success was immediate: three consecutive European Touring Car Championships, tens of national championships and hundreds of individual races in every part of the world. 

In South Africa it was largely spearheaded by the original GTA, the first car imported by the Thompson Brothers in 1965 to be driven by Keith Berrington-Smith. 

The right-hand drive 1600 GTA (one of 50 of the first 500 cars) was successfully campaigned and quickly developed. It was soon taken over by Basil van Rooyen’s Superformance and developed further into one of the most iconic touring cars of South Africa’s motor sport of the late 1960s. 

Carrying racing number Y152 (usually) and driven by Arnold Chatz it was one protagonist of the classic Alfa versus Ford battle with Peter Gough’s Meisner Escort, Y151. 

Further modified, including 2,0-litre GTAm engine and wide body, it was ultimately left in Angola after its last competitive race. 

A further 1300 GTA was imported in 1968 by Alderton Motors, then Johannesburg Alfa Romeo agent and campaigned in the ’68 and ’69 Springbok Series and some production car races shared with other legendary drivers, including Paddy Driver and John Conchie. 

Lesser known in GTA circles was a South African developed and marketed model of the Alfasud. The 1983 Alfasud Export GTA featured Alfa’s 1,5-litre flat four engine with 77 kW in the five-door hatch. 

The GTA nameplate would return again to South Africa in the early 2000s when a 156 was locally developed for Production Car racing. It was joined by a full factory onslaught of three genuine Autodelta/N-Technology prepared 147GTA Production Cars, giving BMW a serious run for their money, variously in the hands of Martin Steyn, Reghardt Roets, Morne Jurgens, Marco da Cunha, and Marc Auby. 

Alfa Romeo offered the 156 GTA and 147 GTA on showroom floors, both powered by a 184 kW 3,2-litre V6 engine with six-speed manual gearboxes. 

For the new Giulia GTA, Alfa Romeo engineers have striven to improve aerodynamics and handling, but, above all, to reduce weight: the same guidelines followed for the 1965 Giulia GTA.

 


The active aerodynamics were specifically studied to increase the downforce. These solutions contain technical know-how that comes directly from Formula 1, thanks to the synergy with Sauber Engineering and the use of the Sauber Aerokit. The same task is assigned to the side skirts, the specific rear spoiler and the active front splitter.

The titanium Akrapovič central exhaust system integrated in the carbon fibre rear diffuser is also new, as are the 20-inch centre lock wheels, appearing for the first time on a sedan. The handling at high speeds has been improved by widening the front and rear wheel tracks by 50 mm and developing a new set of springs, shock absorbers and bushings for the suspension systems. 

On GTAm, the aerodynamic front piece has been optimised to an extreme level, by adding a larger front splitter and a real carbon rear wing, which ensure a perfectly balanced load at high speeds. 

In terms of performance, the 2,9-litre V6 Bi-Turbo, made entirely of aluminium and capable of 375 kW in standard trim, reaches a power output of 390 kW on Giulia GTA thanks to calibration work performed by Alfa Romeo engineers.


Inside, the trim is 100% Alcantara on the dashboard, door panels, glove compartment, side pillars and the central trim on the seats. Alcantara is used even more extensively on the GTAm version, where the rear bench has been removed, leaving room for a fully upholstered ‘basin’, hosting specific mouldings deigned to hold helmets and a fire extinguisher. 

In the new GTAm, the interior is unique in that it features a roll bar, no door panels or rear seats and the door is opened with a belt in place of the handle. 

The work done to reduce vehicle weight has been significant and it has reaped particularly impressive results in the GTA. Here the total weight reduction amounts to 100 kg, thanks to the adoption of lightweight materials such as carbon fibre for the drive shaft, hood, roof, front bumper, front wheel arches, rear wheel arch inserts and the shell of the specific sporting seats with 6-point Sabelt safety belts. 

The result is a weight set around 1 580 kg which, combined with the increase in power to 390 kW brings the power/weight ratio to an excellent 246 kW/ton or 4,1 kg/kW, making Giulia GTA capable of delivering extraordinary performance. Its acceleration from 0 to 100 km/h stops the chronometer at just 3,6 seconds thanks to the Launch Control system. 

The Giulia GTAm is the two-seater configuration approved for on-road use, with front splitter and larger visible rear wing in carbon, the ultimate expression of sportiness. In the GTA version, with the same power, Giulia offers four seats, no rear roll-bar; spoiler and splitter optimised for daily use on the road; the same door panels, seats and windows as those of the Giulia Quadrifoglio. The result is a veritable supercar for everyday use. 

The sales process will be one-to-one, with a Brand ambassador product specialist following each customer from order to delivery. But the buying experience doesn’t stop at the dedicated sales process. Indeed, the new owners will also receive a personalized experience package kit, which includes a Bell helmet in special GTA livery, a full racing set by Alpinestars (race suit, gloves and shoes) and a personalised Goodwool car cover for protecting his or her GTA or GTAm.

 Lotus comeback starts with Emira

It is a name that has been exceedingly quiet for some time but, Lotus is back with its all-new Emira the company says perfectly embodies the ongoing transformation of the Lotus business and brand as well as featuring all the hallmarks expected from a Lotus – striking design, thrilling dynamic performance and outstanding aerodynamics.

Building on the legacy of the Elise, Exige and Evora, the Emira represents a quantum leap forward for Lotus and Matt Windle, Managing Director, Lotus Cars says: “The Emira is a game-changer for Lotus. It stands as a beacon of everything we have achieved to date in the transformation of the business, the embodiment of our progress. It is a highly significant milestone on our path to becoming a truly global performance car brand.” 


The Emira has been developed on a new lightweight bonded aluminium chassis, technology pioneered by Lotus and which remains an intrinsic part of the company’s sports car DNA. That vehicle architecture is wrapped with a design using cues clearly developed from the Evija. Key dimensions of the Emira are length 4 412 mm, width 1 895 mm, height 1 225 mm and wheelbase 2 575 mm.
 

Powering the Emira will be a choice of two petrol engines, the 3,5-litre V6 that powered the Exige and Evora and, from summer 2022, the first new Lotus sports car engine for more than a decade makes its debut, with the Emira powered by AMG. The new-to-Lotus AMG unit is a turbo-charged 2,0-litre four-cylinder ‘i4’ from the performance division of Mercedes-Benz. 


Working with Lotus for the first time, AMG has come on board as technical partner on the Emira programme, with some fundamental changes made to the in-line four-cylinder set-up for its Lotus debut. Transverse-mounted and delivering rear-wheel drive, the unit has been modified with a new air intake system and new exhaust to suit the character of the Emira.
 

The second engine is more familiar, the 3,5-litre supercharged Toyota V6 that is so loved by drivers of the Exige and Evora. Cars will be available with a manual, automatic and Dual Clutch Transmission (DCT). 


Across the Emira range, power output will between 268 kW and 298 kW at launch, with 0-100km/h acceleration in less than 4,5 seconds and top speeds of up to 290km/h. Maximum torque will be 430 Nm and CO2 emissions will start below 180 g/km.
 

Manufacturing will take place at Lotus’ famous home in Hethel, Norfolk, following more than £100-million of new investment in the company’s UK facilities. 

Matt Windle adds: “The Lotus Emira is the most accomplished Lotus road car ever to roll through the Hethel factory gates. Beautifully proportioned with a stunning design inspired by the Evija all-electric hypercar, it’s the perfect package. The Emira is a junior supercar with all the thrills and head-turning characteristics found in the greatest Lotus cars, but at the same time is an everyday sports car that’s high on comfort and functionality, packed with the latest technology demanded by the discerning driver.”
