TMG still developing Lexus LS Sports 650 [w/video]

If you're going to make a super sedan, you'd better do it in Germany. That's where Audi, BMW and Mercedes-Benz do it, along with third parties like Alpina, Brabus and G-Power, among others. Deutschland is the epicenter of the movement, regularly churning out the most powerful four-door rockets in the world. It's also where one of the racing divisions for Toyota has been hard at work on the TMG Sports 650.
Toyota Motorsport GmbH started with a Lexus LS and turned it into a 641-horsepower, twin-turbocharged super sedan it revealed late last year at the Essen Motor Show. But though we haven't heard much about it since then, the team behind Toyota's F1 and Le Mans efforts are apparently still hard at work on the project.
Speaking with Lexus' own UK blog, TMG chief Alastair Moffitt revealed that the project started way back in 2010, shortly after Toyota shut down its F1 program and left the racing team with nothing to do. The 5.0-liter twin-turbo V8 was initially producing as much as 800 horsepower, but has since been refined to 650 so that it could theoretically be put into production and onto the road.

2016 Lexus IS gets revised engine lineup

Look, the old Lexus IS 250 sucked. With a slow, heavy, underpowered, thirsty, 2.5-liter V6 under hood, our own managing editor, Steven Ewing, dubbed it Jennifer Slowpez in his review. While we celebrate its death, we're raising our glass towards a far smarter lineup for Lexus' entry level sedan. As previously reported, the new rear-drive-only IS 200t steps in at the bottom of the range. You can read all about it in our original post from late last month. Today's news focuses on the V6. While the 3.5-liter V6 from the IS 350 will soldier on unchanged, Lexus is adding a detuned variant of Toyota's popular six-cylinder to create the IS 300 AWD. Where the IS 350 pumps out 306 horsepower and 277 pound-feet of torque, the all-wheel-drive-only IS 300 comes to party with a more relaxed 255 hp and 236 lb-ft of torque. That's still a hell of a lot more power than the old IS 250 AWD, which offered just 204 hp and 185 lb-ft of torque. So, there we have it – IS 200t, IS 300 AWD, IS 350, and IS 350 AWD. And of course, Lexus' performance minded F Sport package is available regardless of engine, giving owners a sharper and more stylish character for their sedan. You can check out the nitty gritty details on Lexus' rejiggering of the IS range below. Lexus IS Sport Sedan Gets Revved Up In 2016 With Three Available Engines 2.0L Twin-Scroll Turbocharged Gas Engine for New IS 200t New 3.5L V6 Engine Provides More Options for All-Weather Drive with IS 300 AWD Agile Handling Throughout IS Lineup Available F SPORT Package Heightens Driving Experience July 24, 2015 2016 Lexus IS Sedan Product Information The Lexus IS luxury sport sedan models will continue to delight drivers with their balance of luxury, agility and sportiness as they enter 2016 model year with a three model strategy with IS 200t, IS 300 AWD, and IS 350. The former IS 250 and IS 250 AWD are discontinued. The IS adds to its stable of engines and receives a turbocharged gas engine, bringing the number of engine alternatives to three. Drivers will have a hard time deciding which IS to take home with rear-wheel drive (RWD), all-weather drive (AWD) and F SPORT variants. The new IS 200t, available as RWD only, features a 2.0-liter twin-scroll turbocharged inline four-cylinder engine with intercooler paired to an eight-speed automatic transmission. This engine cranks out 241 hp and has 258 lb.-ft. torque at 1,650-4,400 rpm.

Are you the Lexus GS F?

It's been a while since we've heard rumors of the fabled high-performance Lexus GS F, but thanks to our eager spy photographers, this looks to be our first real proof of the machine's existence. We don't have the usual brace of photos from all angles to work with this time around, our spies saying that every time Lexus' garage door opened, engineers jumped in front of the cameras to prevent the car from being photographed.
Even so, we have a pretty clear glimpse at some significant changes to this GS sedan, including the same staggered, quad-pipe exhaust found on the Lexus IS F. There's also an air diffuser panel nestled between the exhaust outlets, as well as a larger lip spoiler and unique wheels (matching those of the RC coupe) wrapped in high-performance tires.
Last time we heard rumors of the GS F's existence, sources predicted that the M5-fighting sedan would use a tuned version of Lexus' 5.0-liter V8, producing something like 465 horsepower. We have also heard that the automaker plans to reduce weight wherever possible, and that the final curb weight will be something like 3,700 pounds.
