Hartmut Feyhl left AMG after 15 years to start his own tuning company, RennTech, which is now one of the most respected AMG tuners in the world. His products range from simple software upgrades to full racing builds based on AMG street cars. We take his new, 700 horsepower CLS63 for a spin and establish a new benchmark for luxury sedans: must be able to do burnouts while moving at highway speeds.
The 1,100 HP Switzer "Ultimate Street Edition" GTR - /TUNED
It wasn't long ago that driving a 1000+ horsepower car came with
many sacrifices. These were race or show cars, not to be used daily. Enter
the Switzer "Ultimate Street" GTR. On pump gas, it makes 1,000 horsepower with virtually no
downside. On race gas, it makes 1,100 horsepower. And the owner of
this particular GTR uses it as his daily driver to commute to work. Is
enough to get to the office? We'll find out.

The 700 HP Hennessey Camaro ZL1 -- /TUNED
Tuned goes to Sealy, TX to test Hennessey's take on the already potent Camaro ZL1, one of the
loudest cars we've ever had the privilege of driving. We discuss what it's
like to drive a paddle-shifted muscle car and race Hennessey's daily driver
CTS-V "Hammer Wagon" down their private drag strip.
The Tire-Punishing, 400HP Turbo BMW E30! - /TUNED
The BMW E30 is quickly becoming a cult classic among the DIY, autocross,
and track crowd. And though the M3 version may be climbing so quickly in
price, soon no one will be able to afford one, the 325i, as it turns out,
has some chops as a great platform for tuning. Kameron Baker's homebuilt
E30 is just about the nicest one we've seen, and if you think it looks
great, wait till you see how it drives.
The 700 HP VF Engineering BMW M3 - /TUNED
TUNED visits one o our favorite California tuners, VF engineering, who have
upgraded the E92 M3's power, suspension, and brakes in order to turn the m3
from a balanced, focused machine into an absolute monster.
The 800 HP Formula Drift K.Sport 350Z - /TUNED
Tuned goes to Bondurant School of High Performance Driving to meet up with
Formula Drift driver Corey Hosford and his 800 HP Blown LS3 Nissan 350Z
Drift car. We learn what separates a drift car from a race car, and Matt
gets to work on his drifting technique behind the wheel of a monster race
The 750 hp D3 Cadillac CTS-V -- /TUNED
The CTS-V is one of the most tunable sedans money can buy, thanks to its
Corvette-derived drivetrain and robust running gear. Its also quite
practical as a daily driver. We visit well known tuner D3 to see how the
CTS-V takes to their modifications.

Subaru R-STi - JDM vs USDM: A Friendly Rivalry -- /TUNED
In the US, we never got the best Subaru of them all, the first generation
WRX coupe, getting stuck with the fun-but-not-fast 2.5RS version. One of
the more popular upgrades for those cars is the "R-STi" drivetrain swap. In
the season premiere of Tuned, we look at two approaches: the USDM
drivetrain swap, and the JDM drivetrain swap. Which is better? You decide.
