Question: When did the luxury division of the top selling car brand change the body style of the rx 350?

<P0-S0> the acura mdx, or honda mdx as known in japan and australia (only the first generation was imported), is a mid-size three-row luxury crossover, produced by the japanese automaker honda under its acura luxury nameplate since 2000. the alphanumeric moniker stands for "multi-dimensional luxury". <P0-S1> according to honda, the mdx is the best-selling three-row luxury crossover of all time, with cumulative u.s. sales expected to surpass 700,000 units before the end of 2014. it has ranked as the second-best selling luxury crossover after the lexus rx, which offers only two rows of seats. <SEP> <P1-S0> the acura rl is a mid-sized / executive luxury car that was manufactured by the acura division of honda for the 1996–2012 model years over two generations. <P1-S1> the rl was the flagship of the marque, having succeeded the acura legend, and was replaced in 2013 by the acura rlx. <P1-S2> all models of the legend, rl and rlx lines have been adapted from the japanese domestic market honda legend. <P1-S3> the model name "rl" is an abbreviation for "refined luxury." <SEP> <P2-S0> Some buyers lamented the small size of the first Japanese compacts, and both Toyota and Nissan (then known as Datsun) introduced larger cars such as the Toyota Corona Mark II, the Toyota Cressida, the Mazda 616 and Datsun 810, which added passenger space and amenities such as air conditioning, power steering, AM-FM radios, and even power windows and central locking without increasing the price of the vehicle. <P2-S1> A decade after the 1973 oil crisis, Honda, Toyota and Nissan, affected by the 1981 voluntary export restraints, opened US assembly plants and established their luxury divisions (Acura, Lexus and Infiniti, respectively) to distinguish themselves from their mass-market brands. <SEP> <P3-S0> A facelift was designed through late 2010 and patented on 7 January 2011 under design registration number 001845801 - 0004. <P3-S1> The facelift was unveiled at the March 2012 Geneva Motor Show with new wheels, interior colors, new head and tail lamps and new grilles. <P3-S2> New LED running lights were introduced as well. <P3-S3> The F Sport was introduced, with a honeycomb grille, 8 - speed automatic transmission, and a unique sporty interior. <P3-S4> In the US, the new model uses the Lexus Enform telematics system, which includes the Safety Connect SOS system and Shazam tagging. <P3-S5> Sales began worldwide in April 2012 for the RX 350 and RX 450h, with sales for the F - Sport variants starting in July of the same year. <SEP> <P4-S0> While references to verify the manufacturers' claims have been included, there is always the possibility of inaccuracy or hyperbole. <P4-S1> Also note that a single vehicle can be sold concurrently under several nameplates in different markets, as with for example the Nissan Sunny; in such circumstances manufacturers often provide only cumulative units sold figures for all models. <P4-S2> As a result, there is no definitive standard for measuring units sold; Volkswagen has claimed its Beetle as the bestselling car in history as it did not substantially change throughout its production run. <P4-S3> By contrast, Toyota has applied the Corolla nameplate to 11 generations since 1966, which have sold over 40 million through July 2013.
