The Hyundai Genesis Coupé is a rear-wheel drive sports coupe from Hyundai Motor Company, released on October 13, 2008 for the Korean market.
 It is Hyundai's first rear-wheel drive sports coupe, and shares its basic platform with the Hyundai Genesis luxury sedan.
Genesis Motors is the luxury vehicle division of the South Korean automobile manufacturer Hyundai Motor Group.
 Initially envisioned along with the plan for Hyundai's new luxury sedan Hyundai Genesis in 2004, the Genesis brand was officially announced as a standalone marque on 4 November 2015.
The Hyundai Grandeur (Korean: 현대 그랜저, "Geuraenjeo" ) is a mid-size car (initially full-size car) produced by the South Korean manufacturer Hyundai since 1986.
 The Grandeur has evolved through five generations with intermediate restylings, and is marketed under various nameplates worldwide—prominently as the Hyundai Azera (현대 아제라, "Ajera").
 As the Azera, it was considered the flagship model of Hyundai's United States lineup until the arrival of the Genesis sedan.
 Currently the Azera slots between the midsize Sonata and the Genesis sedan.
The Hyundai Dynasty is a premium executive sedan that debuted in 1996.
 The features of the Dynasty were electronically controlled suspension, dual climate control, and power memory seats (front and rear).
 In order to differentiate the Dynasty from its platform-shared smaller Grandeur, Hyundai used a different badge (stylized D logo) for Dynasty.
 The Hyundai Dynasty was produced in Ulsan, South Korea and it was discontinued in 2005.
 The Dynasty was the top level flagship at its introduction, but it was a front wheel drive vehicle.
 It had a higher level of luxury equipment and was available in extended length versions over the more basic Grandeur.
 When the joint luxury flagship Mitsubishi Proudia/Hyundai Equus was introduced, the flagship designation was then removed from the Dynasty and sales suffered as a result with cancellation.
 With the introduction of a separate rear-drive luxury channel launched called Genesis Motors, the market position formally held by the front-wheel drive Dynasty is being replaced by the Hyundai Aslan.
The Hyundai Aslan is a mid-size four-door, five passenger, front-wheel-drive Executive sedan manufactured and marketed by Hyundai since 2014.
 Its interior and exterior are similar to those of the rear-wheel drive Hyundai Genesis but it shares the front-wheel-drive Y6 platform with the Hyundai Grandeur.
 In terms of size, it is situated between the Hyundai Grandeur and the Hyundai Genesis replacing the market segment previously held by the Hyundai Dynasty.
 The word "aslan" is Turkish for lion.
The Genesis G90, also called the Genesis EQ900 (Korean: 제네시스 EQ900 ) in South Korea, is a full-size four-door luxury sedan manufactured by Hyundai's Genesis brand, the successor to the Hyundai Equus brand.
The Genesis G80 (Korean: 제네시스 G80 ) is a four-door, five passenger, executive sedan manufactured by Hyundai's luxury brand Genesis, successor of Hyundai Genesis.
The Hyundai Genesis (Korean: 현대 제네시스 ) is a full-size / executive four-door, five passenger, rear-wheel-drive luxury sedan manufactured and marketed by Hyundai since 2008 and now in its second generation.
The RMR Hyundai Genesis PM580 (RMR PM580, Hyundai PM580, Hyundai RMR PM580) is a LeMans-style race car built by Rhys Millen Racing (RMR) racing to compete in the 2010 Pikes Peak International Hillclimb Unlimited class and designed to break the 2007 record time of 10:01.408 minutes set by Nobuhiro Tajima's in a Suzuki XL7 Hill Climb Special.
The Nissan IDx is a concept car introduced at the 2013 Tokyo Motor Show by Nissan.
 It is supposedly inspired by the Datsun 510.
 The IDx is Nissan's answer to the "RWD tuner craze" that is ongoing and a direct competitor to the Hyundai Genesis coupe & Scion FRS/Subaru BRZ.
 The IDx is aimed at young buyers and racing gamers alike.
 A few quirks the car has that might not make production are the "side view mirrors" that are designed to be cameras rather than traditional mirrors as well as the side-exit exhaust.
 There is a possibility that Nissan is building more IDx concepts because there is a number (003 and 004) instead of a 001 and 002 on each of the concepts.
 With Nissan's looming decision to discontinue several current models such as the Quest, Xterra, Cube and possibly the Juke there is expected room in Nissan's lineup for a new entry-level sports car.
