The facelifted 2013 Lexus RX revealed in leaked brochure somewhere in Japan. It’s one of the top-selling models from one of the top-selling luxury marques. The RX is now on its third iteration, with a fourth on the way – and this appears to be our best look at it yet.

The 2013 Lexus RX is apparently undergoing a facelift that will bring its appearance in line with the brand’s latest design language – centering around the pinched chrome-edged “spindle” grille that characterizes the front of the latest GS sedan. Reshaped headlamps with a strip of LEDs flank either side, and, of course, it’s all riding on new wheels.

While the RX may not be exactly what you’d call “performance-oriented” – floating as it does down the road and communicating less through the steering wheel than you’d expect from a pouting pre-teen behind a slammed bedroom door – the new model is apparently getting an F Sport trim kit. That would include a new front bumper, honeycomb grille, rear spoiler, bigger wheels and tinted lamps, with sportier trim to match on the inside.

We’d expect to see Lexus officially release the new RX sometime within the next few weeks, with a probable debut at the New York Auto Show in April.

Today spy photographers sent us a shot of a Lexus LS TMG Edition.

The spec sheet itself is from TMG, which is an acronym for Toyota Motorsports GmbH, the Japanese firm’s high-performance testing and development facility located in in Cologne, Germany.

The information sheet says that the car is named the Lexus LS TMG Edition and that it comes equipped with a 5.0-liter engine, but makes no word if it’s naturally aspirated or turbocharged, nor if it’s a V8 or an LFA-based V10.

What it does say is that the 5.0-liter unit maxes out at 9,000 rpm and that it delivers an output of 650-horses and a peak torque of 710Nm.

It adds that the car tips the scales at 2,070kg, rides on 20-inch wheels shod in massive tires size 295/35 up front and 345/30 at the rear, and that it completes the 0-100km/h sprint in just 4.2 seconds on its way to a top speed of 320km/h.

The Lexus GS production model was caught today at the Nürburgring circuit. The Lexus GS test mule is covered in plenty of camouflage.

Aside from the body proportions, details like the protruding side sills, the high rising belt line, the “dotted” LEDs and large grille up front, and even the alloy wheel designs, appear remarkably faithful to the concept.

We expect the production model’s exterior dimensions to remain close to those of the prototype, which measured 192.5-in. long, 73.6-in. wide and 57.1-in. tall, meaning that the new GS should be a hair larger than the current model.

No word about potential engine choices yet but chances are that Lexus will stick to a similar lineup to today’s model with 6-cylinder and 8-cylinder gasoline units plus of course, a hybrid version equipped with a gasoline-electric drivetrain.

A more powerful model wearing the F-badge may also be in the cards for the next generation of the GS.

The new Lexus LF-A’s prototype was caught in testing on the Nürburgring rings in Germany. As we see through camouflage, the new Lexus LF-A can definitely be seen sporting a new front- and rear-end, as well as additional sculpting to its side air intakes found ahead of the rear wheel and between the B- and C-pillars.

The Lexus LF-A production version is rumored to produce over 500 hp from a V10 engine, and the car itself should be capable of over 200 mph. Expected price – around $200,000.

Look at the first shot of the Lexus LF-A engine. The engineer’s only opened the hood at the Nurburgring 24 for a moment but we got the spy shot. The engine looks long enough to likely be a V10 as has been previously postulated. The bank angle appears to be 90 degrees for a lower center of gravity than would be available from the normal 72-degree bank angle for a V10. The intake plenum is apparently made up of a composite material, again, likely for both overall weight reduction and and lowering the CG.

You already saw spy shots of Lexus LF-A. Today you can see the Lexus LF-A supercar undergoing final testing before making its public debut later this month at the German Nurburgring 24 hour endurance race.

The range-topping Lexus is running in virtually undisguised form beneath its matte black paintwork. At the front are distinctive swept back headlamps, together with vents cut into the bonnet to aid cooling of the front-mounted motor.

Rough wire mesh covers the rear-mounted radiators, while small round lenses are used in place of the larger production lamp units. Modifications for racing include the large rear spoiler, aerodynamic tweaks to the front bumper and an interior kitted out with a roll cage.

This means that under the bonnet is a V10 engine that should produce around 500bhp. Performance will be scorching, with a top speed well in excess of 200mph.

Lexus bosses are remaining tight-lipped about the launch date of the LF-A. However, if the car runs well at the German endurance race on 24/25 May, then expect to see showroom ready examples in early 2009.

The spy shooters from KGP have caught a new version of the Lexus LF-A near the famed Nurburgring in Germany. The most tell-tale sign that this is likely not a road-going version of the car is its giant, fixed rear wing in place of the retractable one seen on prior prototypes. It also has what appears to be carbon fiber canards on the outer edges of the front clip, which, last time we checked, aren’t often found on road-legal automobiles. The Lexus might be aiming for success in motorsports with the upcoming LF-A, especially after seeing the fine performance of Nissan’s new GT-R in competitive racing.
