The Renault Alpine GTA along with its follow-up, the A610, represent sports coupé automobile models manufactured by the French company Alpine, a subsidiary of Renault, from the end of 1984 until 1995. The GTA designation was primarily an internal code and was officially used only in the UK market; across Europe, it was sold as the Alpine V6 GT or V6 Turbo. This model succeeded the less commercially successful Alpine A310, sharing numerous design aspects such as engine configuration and overall layout. The A610 replaced the GTA in 1991.

Alpine GTA

Introduced in 1985, the Grand Tourisme Alpine (GTA) marked Alpine's inaugural model produced entirely under Renault's ownership. It took over from the Alpine A310, featuring a longer, wider, and taller body incorporating contemporary design cues like integrated bumpers and a distinctive triangular C-pillar paired with an expansive rear window. Maintaining the rear-engine setup powered by the V6 PRV engine, the extensive use of fiberglass and polyester plastic panels helped reduce weight, thereby enhancing performance to rival competitors such as the Porsche 944. Passenger comfort was improved with more practical rear seating and enhanced amenities, including power locking systems. The naturally aspirated version boasted an impressive drag coefficient of 0.28, while the turbocharged variant had a slightly increased figure of 0.30 due to larger tires and additional cooling ducts. Although "GTA" stood for "Grand Tourisme Alpine," most markets marketed it under the Renault Alpine V6 GT or V6 Turbo names. In the UK, trademark issues led to its sale as the Renault GTA.

Departing from its predecessor’s single-piece body construction, the GTA incorporated numerous smaller panels. This change necessitated significant retooling at Alpine’s Dieppe factory but cut assembly time drastically from 130 hours down to 77 hours—an efficiency notable for a specialty vehicle produced in limited numbers. The naturally aspirated version was powered by a 2849 cc PRV engine delivering , offsetting an increase in vehicle weight. Meanwhile, the turbocharged model utilized a reduced displacement of 2.5 liters.

The chassis featured a central backbone design with side impact reinforcements, constructed by Heuliez and assembled at Dieppe. Most parts were sourced through subcontractors. A removable subframe housed the drivetrain, enabling extraction within two hours. Positioned further forward than on the A310, this layout improved weight distribution. The gearbox was adapted from the Renault 30 transmission but included modifications such as taller fourth and fifth gears compared to those found on the GT Turbo model. Initial manufacturing output reached ten units daily; however, average yearly production over six years stabilized at just over 1,000 vehicles—similar to volumes achieved by the A310 V6.

Models

Alpine introduced three principal models intended for consumer use.

V6 GT

Launched in November 1984, the V6 GT served as the entry-level variant. It achieved an impressive aerodynamic efficiency with a drag coefficient (Cx) of 0.28, setting a benchmark within its segment. Equipped with a naturally aspirated V6 engine, production commenced late in 1984, and the model was officially unveiled at the 1985 Amsterdam motor show before reaching dealerships.

Europa Cup model

The Europa Cup edition was introduced in July 1985 specifically for a European single-make racing series. Production was limited to 69 units from 1984 through 1987, with only around seven civilian-registered examples believed to still exist. Each car was factory-issued along with official registration papers, although some lost documentation due to VAT reclamation processes.

V6 Turbo

Debuting in September 1985, the Alpine V6 Turbo (D 501) incorporated improved cooling through an enlarged grille integrated into the rear spoiler, which slightly increased its drag coefficient to 0.30. This model was powered by a turbocharged PRV V6 engine with a displacement of 2458 cc, delivering power output at 5750 rpm and torque at 2500 rpm. These specifications enabled acceleration from zero to 60 mph in 6.3 seconds and a maximum velocity of .

The turbocharged variant significantly boosted sales figures. The right-hand-drive configuration made its first appearance at the 1986 Birmingham Motor Show, marking the GTA’s entry into the UK market.

To comply with more stringent emission regulations in Switzerland and other European territories, a catalyzed version producing 15 hp less was launched in early 1987. This iteration compensated for reduced output by employing lower gear ratios in fourth and fifth gears. Additionally, anti-lock braking systems became available starting in 1988.

In 1989, the Mille Miles limited edition was released in a run of 100 units as part of a brand revitalization effort for Alpine. This edition removed Renault badges and introduced unique Alpine branding and styling cues; however, UK models did not carry Alpine insignia due to trademark limitations.

February 1990 saw the arrival of the Le Mans limited edition featuring an aggressive aerodynamic kit, polyester wheel arch extensions, and BBS-style wheels sized at 8x16" on the front and 10x17" on the rear. Many design elements from this model influenced the later A610 series. Production of standard V6 GT and Turbo models ceased in 1990, while Le Mans editions continued until February 1991, totaling 325 units.

That same year, domestic models were downgraded to catalyzed engines producing less power (down to ), due to tightening emission standards—much to the disappointment of enthusiasts. To address this, tuner Danielson SA developed an enhanced Le Mans version delivering .

Federalized version

Renault and Alpine explored introducing the GTA to the US market through American Motors Corporation (AMC), which Renault partially owned at that time. A US-compliant V6 Turbo variant was engineered featuring retractable headlights replacing fixed units, larger impact-absorbing bumpers, integrated side markers, and an expanded front grille for better engine cooling. The chassis underwent modifications including pressed sheet metal substituting front tubular structures, added energy absorbers, reinforced doors, and doubled side reinforcements. Many structural improvements from this GTA USA model were later incorporated into the A610.

Although initially slated for a 1986 release, development delays postponed the federalized Alpine V6 Turbo launch. The American version included an emissions-controlled engine rated at 180 hp, larger safety bumpers, flip-up headlamps, enhanced crash protection features, and softer suspension tuning. AMC/Renault aimed for a mid-1987 introduction targeting annual sales of approximately 3,000 units plus an additional 300 for Canada. However, following Renault’s divestment from AMC to Chrysler in March 1987 and its retreat from North America, the project was discontinued amid concerns regarding AMC dealers’ capacity to support such a sophisticated and costly vehicle. Ultimately, only 21 pre-production cars were manufactured; of these, 12 were sold directly by Alpine to select customers in France.

Le Mans

Introduced in February 1990 with an initial production target of 300 units, the Alpine Le Mans saw a total of 325 vehicles manufactured by February 1991. Equipped with a catalyzed V6 Turbo engine delivering 185 PS (a reduction from the previous 200 PS), it showcased a body kit influenced by a German tuner. This included broadened fenders seamlessly integrated with the front fascia, repositioned front turn signals mounted on the bumper, rocker panels, and distinctive BBS-style wheels featuring dummy central nuts. Available in three color options—Alpine Blue, Imperial Red, and Beetle Green—this design later inspired the development of the A610 model.

In response to French emissions standards enacted in 1990, Alpine’s V6 Turbo engine output was reduced from 200 to 185 PS. This adjustment was necessitated by the rear-engine layout constraints and the high expense of pollution control systems incompatible with limited production runs. As a result, the top speed declined from 250 km/h to approximately 240 km/h, while other performance parameters remained largely unaffected.

Danielson SA offered an aftermarket tuning package that enhanced engine output from 185 PS up to 210 PS by refining the engine management system. This upgrade nearly restored the original power levels of the non-catalyzed V6 Turbo and allowed acceleration figures comparable to those of a Porsche 911 (964) Carrera 2 or Ferrari 348 TB (achieving 100–140 km/h in fifth gear within 9.3 seconds). The tuning modification was priced at roughly 16,000 FRF in addition to the base cost of 375,000 FRF.


Specifications


Alpine A610

Manufactured by the French automaker Alpine, a subsidiary of Renault, the Alpine A610 was produced between 1991 and 1995 as the successor to the Alpine GTA. Due to budget constraints during development, its styling remained very similar to the GTA, especially the US-spec GTA with pop-up headlights, although only the window design was retained from the previous model. The A610 upheld Alpine's traditional features, including a rear-mounted engine and a steel backbone chassis. To maintain Alpine's performance-focused reputation and avoid direct Renault branding, the car was marketed exclusively under the Alpine name.

The vehicle was equipped with an enlarged turbocharged PRV engine V6 that generated at 5,750 rpm and torque of at 2,900 rpm. In 1993, the engine capacity was slightly reduced to to meet Swiss taxation requirements.

Among its special editions was the A610 Albertville 92, created for the 1992 Winter Olympics VIP transportation. This version sported a distinctive Gardenia White exterior and interior but retained standard mechanical components. The A610 Magny-Cours edition celebrated Williams-Renault’s triumph at the 1991 French Grand Prix; only 31 units were made, featuring unique paint schemes, interior trims, and matching rims with "Magny-Cours" decals.

Although it received favorable reviews and praise from the British television program Top Gear, sales of the A610 did not surpass those of its predecessor and production ceased in 1995. This marked the conclusion of Alpine’s manufacturing until the brand was revived with the introduction of the Alpine A110 in 2017. Following the A610’s discontinuation, the Dieppe plant shifted focus to producing the Renault Spider, which saw 818 units built (including 67 right-hand-drive models), though sales declined significantly after 1993.

A notable incident involved a rare right-hand-drive A610 being destroyed during Jeremy Clarkson’s 2007 Supercar Showdown when it collided with a concrete barrier.
