Question: When did the luxury division of the maker of the Toyopet Master change the body style of the rx 350?

<P0-S0> The Toyopet Master, introduced in January 1955, is a passenger car that was an update to the SF/RH model with a modernized body. <P0-S1> As for its predecessor, it has a ladder frame with leaf sprung front and rear axles. <P0-S2> The Toyopet Master was an evolution of an earlier Toyota sedan called the Toyota SF/RH model (also known as the Super), and was sold in parallel with the first Toyota Crown. <P0-S3> The more conservative Master was introduced as a frugally equipped version meant for taxi usage. <P0-S4> The Master and Crown shared the same R-series engine, which produces in the Master. <P0-S5> It was sold at a chain of Toyota Japan dealerships called "Toyota Store", next to the more upscale Crown, which was intended as a private purchase alternative to the Master. <SEP> <P1-S0> from september 1947, toyota's small - sized vehicles were sold under the name ``toyopet ''(トヨペット). <P1-S1> the first vehicle sold under this name was the toyopet sa, but it also included vehicles such as the toyopet sb light truck, toyopet stout light truck, toyopet crown, toyopet master, and the toyopet corona. <P1-S2> the word`` toyopet (japanese article)'' was a nickname given to the toyota sa due to its small size, as the result of a naming contest the toyota company organized in 1947. however, when toyota eventually entered the american market in 1957 with the crown, the name was not well received due to connotations of toys and pets. <P1-S3> the name was soon dropped for the american market, but continued in other markets until the mid-1960s. <SEP> <P2-S0> A facelift was designed through late 2010 and patented on 7 January 2011 under design registration number 001845801 - 0004. <P2-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. <P2-S2> New LED running lights were introduced as well. <P2-S3> The F Sport was introduced, with a honeycomb grille, 8 - speed automatic transmission, and a unique sporty interior. <P2-S4> In the US, the new model uses the Lexus Enform telematics system, which includes the Safety Connect SOS system and Shazam tagging. <P2-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> <P3-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. <P3-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> <P4-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". <P4-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.
