Lexus has launched the RX 270 in Japan this week, which will be powered by the 1AR-FE 2.7L engine and putting out 187hp with torque of 252Nm.

The RX 270 was also announced for Russia, and it’s expected (for some time) that the low-displacement version of Lexus’ most popular vehicle will also be available in China at some point.

An RX Art Work special edition was also released today by Lexus Japan, who have teamed up with Stone Designs on some wild interior color schemes:

Here’s some detail shots of the interior:

Both this RX and the previously mentioned IS are really quite playful — quirky even — and while it’s tough to imagine a market for these colors in North America, but I’m really excited to see this kind of customization coming out of Japan.

(Also noticed, the RX 270 has started production is now available in Japan.)

The Bangkok Post has some engine variation rumors regarding the RX & LS:

Later this year, Japan’s top nameplate is set to offer a third engine variant of its RX sport-utility vehicle in the guise of RX270 with 2WD. For the first time, the new entry-level RX would be getting a four-cylinder petrol engine currently used in the Toyota Fortuner and Land Cruiser Prado.

Such a move would help widen the RX customer base, which currently has only two pricey options including the V6-powered RX350 and hybrid-driven RX450h, both of which are priced at over B5m due to 50% excise tax.

Earlier, Lexus had pledged to not build a four-pot motor for the RX in the form of RX240 (Toyota Harrier-style) fearing a diluted image.[..]

For long, Thai product planners have aspired for a six-pot unit for the flagship LS saloon which its parent firm in Japan refused to develop.

Sources say it is possible the next-generation LS could see a V6 option alongside the V8 (LS460) and hybrid (LS600h) so it can compete with the BMW 730i and Mercedes-Benz S300 on the B8m front. A hybrid version using the V6 petrol/electric combination of the RX450h and GS450h is also possible.

A RX 240 wouldn’t be entirely out of the question, after all, the ES 240 has been available in China since last year — however, I’m sure Lexus will wait to see how the RX 270 is received before making any decision.

As for the LS V6 rumor, it’s an older rumor, and it certainly makes sense given the import taxes placed on big V8s in some countries. More interesting is the thought of using the hybrid/V6 from the RXh, which would turn a V6 flagship sedan into something with much larger potential appeal.

LS 450h, anyone?

Toyota & Tesla are now two weeks into their partnership (in which Toyota purchased a $50M stake in Tesla), and it’s rumored that their first joint-project will be converting a Lexus RX to a full electric prototype:

Tesla said July 10 that it will deliver two prototypes vehicles to Toyota this month without identifying the models. While Toyota also aims to test an electric Corolla compact car, the RAV4 and RX light trucks are better suited to the weight of Tesla’s battery pack, said the person, who asked not to be identified because the vehicles haven’t been announced yet.

The target for a model developed with Tesla would be for a car that costs about $40,000 with 150 miles (240 kilometers) of driving range per charge, the person familiar with the plans said.

“Toyota and Tesla engineering teams have made a lot of progress in a short amount of time,” JB Straubel, Tesla’s chief technology officer, said in a July 10 e-mail message.

It may not be a vehicle as exciting as Tesla’s own Roadster, but with the RX already engineered to support a battery pack with its hybrid version, it’s a natural choice to be prototyped using the Tesla electric platform.

Even more than the models chosen, I’m surprised by the speed of this partnership — I wouldn’t have expected an announcement so soon, never mind the possibility that we may see a full-electric Lexus prototype before the year is out.

The Insurance Institute for Highway Safety (IIHS) has awarded the 2010 Lexus RX its TOP SAFETY PICK award.

This designation recognizes the RX for earning the highest possible rating for front, side, rollover, and rear crash protection, along with being equipped with electronic stability control, which is standard.

Lexus South Africa continues its analogous theme with this commercial for the RX 450h, comparing it to the Namaqualand flowers found in the country:

The complexity of a hybrid system working in harmony finds a beautiful analogy in nature, with the setting also providing an ecologically-minded backdrop; still, the vehicle is billed as a performance hybrid, suggesting that it can combine the best of both worlds—efficiency and power. The video is artfully presented as well, showcasing the beautiful intricacies of nature.
