hevrolet is looking to make a statement with
the Corvette ZR1. While special versions of
previous models have kept pace with rival
sports cars, such as the Porsche 911 and various
Aston Martins, the Corvette has never been a supercar
contender able to deliver Ferrari-like performance
and refinement.
The 2025 ZR1 changes that.
This time the ZR1 is packing the most powerful engine
in General Motors' 115-year history. By placing
the engine behind the driver and paying particular attention
to weight, handling and aerodynamics, Chevrolet
aims to elevate the ZR1 into the rarified air of the
world's highest-performing supercars.
Here are features illustrating how Chevrolet outfitted
the ZR1 for its new mission.

1. LT7 engine
It's a 5.5-liter twin-turbo V-8 with a flat plane crankshaft.
It makes 1,064 hp - highest ever in an American
car, says GM - and 828 pound-feet of torque. The engine
can rev safely to 8,000
rpm, higher than most
high -performance four -
cylinder motors. The turbos,
integrated into the exhaust
manifolds, provide
as much as 20 pounds of
boost and can withstand
temperatures as high as
1,900 degrees Fahrenheit.
GM's engine designers created cylinder heads, cams
and intake, cooling and lubrication systems that can
sustain driving at extremely high speeds. Top speed: at
least 215 mph.
2. Split rear window
In 1963, Chevrolet built 21,513 Corvettes, and half of
them - 10,594 - were coupes with the split rear window;
the rest were
convertibles. Though
the one-year-only feature
was not popular
then, it has become
one of the most revered
and iconic styling
cues in the car's
71-year history. It's back for the 2025 ZR1 coupe. While
the original split rear window was strictly cosmetic, the
new one is functional. It helps vent heat from the midmounted
engine.
3. Wheels
Made by Australia's Carbon Revolution, the onepiece
five-spoke carbon fiber wheels do more than just
look good. Each wheel weighs about 10 pounds less
than aluminum wheels. That
reduced unsprung
weight helps improve steering, braking and handling.
At 21 inches tall and 13 inches wide, the rear wheels
are the world's widest made of carbon fiber.
4. Body
For a car that can top 215 mph, precise air management
is a critical safety requirement. Corvette sculptors
devised a flow-through hood that has key functions:
create downforce and cool the air going into the
engine. Spoilers, splitters, wickers, moldings and modified
side scoops help the track version of the ZR1 generate
up to 1,200 pounds of downforce and cool the
brakes.
5. Easter egg
While Zora ArkusDuntov
is the undisputed
father of the
Corvette - he saved
it from cancellation
in the mid-1950s -
recently retired chief
engineer Tadge Juechter
oversaw development
of the fastest,
highest-horsepower
and best-handling versions
of the car, including the midengine eighth generation.
GM has honored him with a silhouette of his
bust on every ZR1.
MW is bringing a wagon variant
of its M5 sedan to the U.S.
The 2025 BMW M5 Touring
will start at $122,675 including
shipping and arrive late this year.
The model debuted at Monterey Car
Week in Carmel, Calif.
The third-generation M5 Touring features
a drivetrain similar to that of the
640-hp M Hybrid V8 GTP race car, BMW
said. The performance plug-in hybrid
pairs a 4.4-liter high-revving twin-turbocharged
V-8 engine with an electric motor
integrated into the transmission.
The M5 Touring offers an estimated
zero-emission driving range of up to
25 miles on a charge and sprints from
0 to 60 mph in 3.5 seconds.
The wagon is intended to elevate
BMW's performance subbrand in the
U.S., which accounts for 40 percent of
global M vehicle sales.

2025 BMW M5
Touring arrives in
the U.S. this year
in April said that while wagons are not
big sellers in the U.S., " they have a core
following who will be waiting with
cash in hand to pick up an M5 wagon
as soon as it arrives. "
The M5 Touring's athletic look hints
at the performance under its hood.
The wagon sports a newly designed
BMW M kidney grille with the M5
badge on the horizontal double bar.
The center of the grille houses sensors
for the driver-assistance systems,
and the lower section features a pair of
small air intakes. The central lower air
intake is below the grille.
The M wagon has a stretched roofline,
roof spoiler and prominent wheel
arches. Slim rear lights extend into the
sides, while vertical reflectors on the
outer edges of the rear accentuate the
width and powerful stance.
A two-section diffuser helps maximize
aerodynamics and increase traction,
BMW said. Quad exhaust tailpipes
are integrated into the left and
right of the rear apron.

Lambo sees the future:
The Temerario hybrid

amborghini has rounded out
its hybrid product portfolio
with the introduction of the Temerario
coupe, the successor
to the Huracan.
The Temerario, built on a new aluminum
chassis, is powered by a 4-liter
biturbo V-8 engine with three electric
motors for 907 hp. The Temerario has a
3.8-kilowatt-hour battery between the
V-8 and its eight-speed dual-clutch
transmission.
The Temerario, which debuted at
Monterey Car Week, is the third hybrid
in Lamborghini's lineup, following the
Revuelto supercar and the updated
Urus plug-in hybrid SUV.
The move to a hybrid V-8 is significant
for the Italian exotic brand. The
Huracan, first launched in 2014, was

outfitted only with a V-10 and grew to
include several variants.
Lamborghini said the Temerario's
design " points towards the future " of
the automaker's midengine sports
cars. Design similarities from the Revuelto
and Urus are evident inside and
out.
There's an 8.4-inch display on the
center console, a 12.3-inch digital instrument
cluster and a 9.1-inch screen
in front of the passenger seat.
The brand said there is more headroom,
legroom and visibility compared
with the Huracan. There's also a
new 18-way comfort seat that is heated
and ventilated, Lamborghini said.
Pricing is set to start near $350,000.
The Temerario is set to launch globally
in the third quarter of 2025. Lamborghini
in July said Huracan production
would end in December.
