The Audi R8 ("Typ" 42) is a mid-engine, 2-seater sports car, which uses Audi's trademark quattro permanent all-wheel drive system.
 It was introduced by the German car manufacturer Audi AG in 2006.
The Infiniti QX70 (formerly called the Infiniti FX until 2013) is a mid-size luxury crossover SUV produced by the Nissan-owned Infiniti luxury vehicle brand between the 2003-2017 model year.
 The FX replaced the QX4 as Infiniti's mid-size SUV, although the QX4 was larger than the FX.
 It shares the same FM platform as the rear-wheel drive Nissan 370Z, and it "made no claims of climbing mountains."
 Rather, its aggressive shape promised style and quick handling.
 The similarly sized Nissan Murano is based on the same D platform as the front-wheel drive Nissan Altima.
 The FX and QX56, that do not have Nissan-branded equivalents, are not sold in Japan.
The Pontiac Bonneville Special is a purpose-built concept car unveiled at the General Motors Motorama in 1954, the first 2-seater sports car Pontiac had ever produced.
 Conceived by renowned designer Harley J. Earl and hand built by Homer C. LaGassey Jr. and Paul Gilland, the "Special" is a grand touring sport coupé that incorporated innovative styling like a Plexiglas canopy with gull-wing windows on a sleek fiberglass body.
 The name "Bonneville" was meant to convey high performance, inspired by a trip Earl had taken to Bonneville Salt Flats in Utah to observe speed trials there.
 It was the first GM vehicle to carry the name, subsequently given to the Division's full-size performance car, the Bonneville, which carried it for 47 years.
The Infiniti G-series is a line of compact executive/entry-level luxury sports car produced by the Infiniti division of Nissan for the 1991–1996 and 1999–present model years.
 The first two generations of the Infiniti G (P10 and P11) were sedans based on the Nissan Primera.
 Beginning with its third generation (V35), the Infiniti G have been rebadged versions of the Nissan Skyline line of sedans and coupes that were exported to the United States and Canada.
 The current incarnation is the fourth generation (V36) which introduced the hardtop coupe convertible.
 The Nissan FM platform, on top of which the third and fourth generations (V35 and V36) of the Infiniti G have been built, also underpins the Nissan 370Z and has shared components with the Infiniti M, Infiniti EX, and Infiniti FX.

 After the SLS AMG, it is the second sports car developed entirely in-house by Mercedes-AMG.
 The car is produced in two performance variations, with the "GT S" (C120) having a slightly higher performance.
 Both models went on sale in March 2015, with a "GT3" racing variant of the car expected to be released in 2016.
 All variants are assembled at the Mercedes-Benz plant in Sindelfingen, Germany.
LMX Sirex (also sold as Sirex LMS) was a 2-door, 2-seater sports car of Italian origin.
 The car was the only model produced by LMX Automobile S.R.L. (Linea Moderna Executive), a company founded by Michel Liprandi and Giovanni Mandelli.
 The body of the LMX Sirex was designed by Franco Scaglione.
 The LMX Sirex was introduced during the 1968 Turin Auto Show.
 However, as Liprandi and Mandelli could not afford an official stand, the car was shown outside the exhibition hall.
The Infiniti EX is a Compact luxury crossover SUV.
 It is based on the FM platform shared with the Infiniti G, M, and FX.
The Nissan 370Z (known as the Fairlady Z Z34 in Japan) is a 2-door, 2-seater sports car (S-segment in Europe) manufactured by Nissan Motor Company.
 It was announced on October 29, 2006 and was first shown at an event in Los Angeles ahead of the 2008 Greater LA Auto Show, before being officially unveiled at the show itself.

The Nissan Fuga (Japanese: 日産・フーガ "Nissan Fūga") is a full-size luxury sedan produced by Japanese automaker Nissan since October 2004.
 It is built on a wider, stretched wheelbase version of the Nissan FM platform.
 After the Nissan Cima and Nissan President were discontinued in August 2010, the Fuga became Nissan's flagship vehicle.
 In North America and Europe, the Fuga is sold as the second and third-generation Infiniti M (Q70 from 2014), where it has been the flagship of the Infiniti luxury division of Nissan since 2006.
The Nissan FM platform is a modern FR automobile layout.
 The name is derived from the "front midships" location of the engine, with its center of mass located behind the front axle centerline, shifting weight to the middle of the car, leaving the front suspension less encumbered.
 The engine is pushed as far back to the firewall as possible, creating a weight distribution close to 50:50 and enabling the front wheels to be placed close to the corners for better handling.
 This platform debuted with the 2001 V35-series Nissan Skyline, and was then used as the basis of nearly all of Nissan's rear and all-wheel drive applications.
 The platform was revised for use in the JDM Nissan Fuga/USDM Infiniti M35/45, being stretched in wheelbase and reinforced for additional torsional rigidity, a version referred to as the "enhanced FM" platform.
 The GT-R is built on Nissan's Premium Midship (PM) platform, an evolution of the Front Midship (FM) architecture.

Question: Which car is a 2-door, 2-seater sports car that shares the same FM platform as the Infiniti QX70?
Answer: Nissan 370Z
